AND
"GREEN BELT" RESERVE SANDRINGHAM
1. INTRODUCTION
1.1 In 1988 Council became aware through a technical report ** prepared by Pak-Poy Kneebone Pty Ltd for Pacific Dunlop Batteries Pty Ltd that the land Council owns adjoining their former battery manufacturing plant site was contaminated (to various degrees at eight sample locations) by lead and other heavy metals. The land situated at and extending between the eastern ends of Spring Street and Holloway Road Sandringham is known as the "Merindah Avenue" land and "Green Belt" Reserve. The land was previously used for sand extraction and as a municipal tip. More recently the Merindah Avenue land has been used as an undeveloped grassed area with the Green Belt being planted with trees and shrubs to form an "urban forest" as a buffer between the industrial estate and neighbouring residential areas.
1.2 The tests and analysis carried out by Pak-Poy were for heavy metal contaminat ion. The report shows contamination in certain locations on the Council land of surface and subsurface soil by lead and associated elements including:-
Metallic lead Antimonial lead Lead oxide Lead sulphate

Refer to Appendix 1, 2 & 3
1.4 The report finds that atmospheric dispersal through the manufacture of lead oxide could have occurred over a wide area leading to surface contamination. The use of acidic solutions could also affect soil pH levels, further lead that was mixed with the landfill could also have caused subsurface contamination.

4.1 Existing Conditions of the General Area
-1 The earliest material reviewed (Council rate and valuation records) dates to the early 1940's. At this time, the z'-. general area was undeveloped scrub, land used for market fls -I LL&.': gardenina and the beginnings of residential subdivision and development for detached houses.
4.2 Existing Site Conditions 1945 d!.W-x- .1 The 1945 Crown Lands and Survey aerial photograph indicates -- the land use of the site and neighbouring area.
.2 The Merindah Avenue & Green Belt land appear to be excavated for their southern half whilst the northern half is undeveloped scrub with no evidence of excavations or dumping. The north eastern section (where Scout Hall is now located and an area of land further south) appears still to be occupied by market gardening in conjunction with the market gardening occurring on the land to the east (where Dunlop would establish).
.3 The southern section of the current Green Belt (along southern boundary of former Pacific Dunlop site and Spring Street) is occupied by a residential property and market gardening. The area to the south (now Spring Street, residential properties and the link to the Green Belt) appears as undeveloped scrub land transacted by paths and roadways (evident in aerial photographs and 1949 Sandringham Planning Scheme Existing Conditions Survey Plan).
4.3 Site ownershiE
.1 The area under investigation comprising the "Merindah Avenue" and "Green Belt" land was, around this time, in two parcels separately owned. (Map ) Edward May Grant owned and occupied the larger part of the area. The site generally occupied by the Scout Hall was separately owned by Palmson Day Whitlock. (Source: Council rate/valuation records. )
4.4 Use of the Council Land
.1 Grant used the land as a sand pit to extract sand €or use in local road construction and had a rubbish contract with the Council. (Source: Various personal accounts on file.) Other evidence available also suggests that Grant used the land to spell his horses.

4.4 Use of the Council Land (cont'd)
.2 The site was known as and referred to as "Mick Grant's Pit" (Source: Various personal accounts on file.)
5. SITE CONDITIONS AND USE AS MUNICIPAL TIP 1948 - 1955
5.1 Site ownershiE
.1 A Council minute dated March 25, 1947 refers to Council's purchase of "Grant's Pit" - purchased in late 1947. (Source: Council Minutes.)
5.2 Use of the land for tipping I .1 After Grant's death in 1947, occupied by Council and used as a dump for the Council's Spring Street garbage destruc (Source: Various Islons. Dersonal.. accounts on file). Kitchen waste .-A,, mainlv2 --fish) from the "Stork Club" (Hancock's Theatre Restaurant) was dumped at this site. O'Mara refers to collection every Monday and Friday.
-2 The site's use for tipping appears to have commenced in 1948, after Council's purchase of the land, and finished in 1953. Lloyd Palmer suggest an operational time of 2 - 3 years closing soon after he started with Council in March, 1952. However in variance he also suggests the Scout Hall was completed at the tail end of the land's use. The Scout Hall was completed in August, 1953.
.3 The tip was used to deposit remains from the Council's Spring Street destructor. O'Mara refer to a once weekly collection of the burnt waste. The site was used as a stop-gap or on emergencies whilst the Wangara Road tip came into operation in the mid 1950's (O'Mara evidence). The Spring Street destructor ceased operation at the end of 1951 or early in 1952 (Palmer's evidence).
-4 Evidence from Cockburn suggests the sand pit operated until 1953/54 by Mr Jim Stevens, after which it was used as an open fill tip by Council involving burning of refuse in-situ with some land fill added from time-to-time.
.5 Evidence from Cockburn suggests Council rubbish collections, industrial waste and privately delivered /rubbish was dumped at the site. Palmer and O'Mara confir: bdp c", uiCouncil vehicles, garbage trucks and collections. Davies cites the tip's use by other local factories and
-9 businesses including______. Flavells metal works.

.6 It appears based on Palmer's evidence that no regulations or notices were displayed and that no Council by-laws existed over what material was deposited. There were no . . _- restrictions on what was deposited at the tip--site other than s.an~t'ary~r.egulat-.ions; .The~-t-lrp-wa-s ..o.pen.- to. th-e-. ge.n.e-r-ar pubiic and DunloFTas ableand did use the tip (confirmed ------...... --______~- by Davies). Permits for pri-Gate tipping were obtained from the Town Hall generally for household rubbish.
-7 Evidence suggests the tipping area was confined to an area towards the Spring Street frontage to a depth of 2m (O'Mara suggests depth of 2-3m; Davies 12') and adjacent to the western boundary of the former Dunlop factory. The former sand pits were used for dumping and open trenches were dug and filled with garbage. (Source: Various personal accounts on file.)
,8 The deepest sect ion of the tip was at the Spring Street end of the land. O'Mara recollected bulldozers dig trenches along the eastern side (Dunlop side) towards the Scout Hall perhaps 2 trenches 6' - 7' deep fairly long but the width of a bulldozer blade.
-9 Entrance to the tip was off Spring Street (south-east) corner. Similarly access to the Dunlop factory was from Spring Street; that land now contained in the Green Belt along the southern boundary of the Dunlop site.
5.3 Dunlop's use of the ti2
.I The Dunlop factories commenced development in 1948/49 with alterations and extensions occurring through to the 1960's.
.2 Cockburn's evidence alleges Dunlop used the tip site to "dump liquid chemical waste, solid waste, and sludge-like material". Davies confirms Dunlop dumped waste but denies Dunlop dumped lead. According to Davies the waste comprised packing crates, smashed hard rubber battery bases and plastic/hard rubber battery caps. The only solid lead that would have been deposited would have been the lead brushes connected to the plastic caps. -uLtu-&&7 .3 Cockburn nominates locations approximately 30m west and lOOm from the southwest corner boundary of Dunlop. Material deposited in the 2m deep depressions included white effluent, grey powder, metallic lead scrap, and broken battesy casings. O'Mara & Davies refer to dumping in one isolated position midway along the factory; neither was not aware of them depositing lead or sludge.

.4 Solid waste was dumped on land to the south of the Dunlop boundary; some material is still visible on and below the surface. (Cockburn & Davies). Evidence prepared by various people (Stuchberry, Davies & Cockburn) indicates that Dunlop scattered hard materials, old casings and plastic fittings over the car-park-- to compact for the driveway and vehicle access. ,< -. ';i rC/?CO,/€.& . .5 Cockburn also suggest emissions of dust containing lead compounds occurred through discharge from vents, through cracks in the building, storage of drums and spillage on the property, liquid discharges from pipes, sewerage connections, and storm water drains.
.6 The Pacific Dunlop Soils Investigations Report makes some mention of the use of the Council land for dumping by Council and, possibly, Pacific Dunlop. The report nominates the former sand pits outside the western boundary of the former Pacific Dunlop site as a dumping location. (Source: Pacific Dunlop Soils Investigation Report, September, 1988.)
.7 The Investigations Report specifies test locations that are contaminated. (Source: Pacific Dunlop Soils Investigations Report, September, 1988.)
5.4 Dunlop processes
-1 The old factory building closest to the western boundary of Dunlop was used as the battery manufacturing plant from 1949 onwards. The eastern factory was used originally as Dunlop pillow factory until the late 1960's.
.2 The southern portion of the western factory was used for battery manufacturing and formation of plates.
.3 From the plant's inception until 1965 lead ingots were brought on-site and melted so that lead oxide was produced in a powder form on-site in the southern section of the western factory. The southern filter tower came into operation at this time.
.4 Lead oxide and paste was retrieved through daily washing down of equipment which was collected into drainage channels and setting sludge tanks. These tanks were located in the south western corner of the Dunlop site where barrels of waste were also stored and according to Davies sometimes spilled.

.5 Battery recharging used sulpheric acid, the waste from which went through a neutralizing process then into a settlement pondage area to the north of the western factory. The pondage area was used from 1949 - 1959/60. Dunlop instructed that all waste be neutralised but there was no monitoring of the pondage. It could have contained lead oxide.
5.5 Site conditions
.1 The Sandringham Planning Scheme (1949) proposed the reservation of part of the land €or "new open space" and zoned the "Merindah Avenue" land as residential (for allotments and roadway). (Source: Sandringham Planning Scheme (1949) and Council records.)
-2 The '1951 aerial photographs show a deeply excavated area covering the southern half of the site with some possible depositing along the site's eastern boundary. (Source: Aerial photos.)
.3 The northern half, including that section previously occupied by market gardens appears as undisturbed scrub. The area now part of the "Green Belt" along the southern side of the Pacific Dunlop site appears used for vehicular access to the factories, and retains the former dwelling. Use of this area for Dunlop car-parking is confirmed by Stuchberry, Adams, and Cockburn statements. Area was used €or car-parking until 1961/62.
.4 The existing Scout Hall was built on the Holloway Road frontage in August, 1953. ( Source : Counci 1 rates/valuations records.) Extensions to the Hall occurred in 1965. Twelve months later high acid levels in soil caused deterioration of cement mortar and breakage of pipes (Adams' statement.)
.5 The 1954 aerial photo indicates excavations again through the southern half of the site with some back-filling of the southeast section. There is some northern extension o€ the excavations which slope to the deeper southern section.
.6 The northern section remains generally undisturbed with the Scout Hall clearly defined.
.7 The southern section of the "Green Belt" remains used for car-parking and access with a dwelling.

6.1 The tip was closed in 1953 (Palmer cites closure coincided construction of Scout Hall in August 1953; O'Mara cites after Holloway Road was constructed).
6.2 The soil from road construction here and from Beaumaris was used to fill the site and the northern portion of Dunlop (O'Mara's statement).
6.3 Evidence suggest that in 1955 Council commenced refilling the sand pit with f i'll from streetworks. (Source: Personal accounts, Anderson.)
6.4 The 1956 aerial photograph confirms the filling of the southern area of the land which left a section through the middle of the site being used for dumping.
6.5 The 1958 aerial photograph indicate the filling and revegetation of the site is more complete. There appears to be some variations in levels suggesting further filling in small areas.
6.6 The 1960 aerial photograph indicate revegetation completed but a swath through the middle of the site still being depressed. Vehicle car-parking and access occurring along the eastern boundary with.the Dunlop site.
6.7 In 1962, Spring Street was constructed.
7. USE OF THE LAND SINCE TIP CLOSURE
7.1 Plan of Subdivision
.1 Council prepared and had sealed a plan of subdivision €or the "Merindah Avenue" land in 1963 and 1964.
7.2 1976 Geotechnical report on fill
.1 A geotechnical report was prepared by A S James Pty Ltd €or Council on the "Merindah Avenue" subdivision, dated 19 November 1976.
.2 The A S James report was commissioned to determine the extent of the fill on the land contained within the proposed "Merindah Avenue" subdivision. The bore tests did not involve any laboratory analysis.

-3 The conclusion of the report were that "filling of any significance appeared to be confined to the southern end of the site. Although no direct evidence was found the report contends that some of the fine surface soils could have been the result of overall levelling of the area rather than being natural. The report's conclusions confirms the other evidence presented.
.4 The bore samples taken ranged in depth from 2.5m to 5.0m. The southern half of the site is where there is an occurrence of fill at depths ranging from .8m to 4.2m The depth getting deeper closer to Spring Street.
7.3 Current Use and Zoning
.1 The Merindah Avenue land continues to be undeveloped grassed area, used generally for passive recreation. The area known as the "Green Belt" was replanted as an urban forest in 1988.
-2 Under the Sandringham Planning Scheme the "Merindah Avenue" land is zoned Residential C as are the surrounding residential properties. The "Green Belt" Reserve is reserved either as Existing or Proposed Public Open Space. The former Pacific Dunlop site is zoned General Industrial. The following zoning plan illustrates the zoning of the area.
7.: EPA Background tests of local area
-1 The EPA took samples from 8 sites 'within the immediate area; two within (sites Nos.3 & 5) the Merindah Avenue land. Test site No.7 within the Green Belt (south of Spring Street and outside of the investigations area displayed the highest elevation of lead levels.
7.5 EPA requirements for the clean-up of Pacific Dunlop site
-1 The EPA has issued clean-up notices on the owners of the former Pacific Dunlop battery manufacture site. A clean-up notice (under S.62A of the Environment Protection Act 1970) was issued on 20 June 1990 which specifies the works and standards required for the clean-up of that site. These include -
"1. Remove all soil with a total lead content greater than 300 parts per million (ppm), as determined using EPA publication 139 "Chemical Analysis of Polluted Soils", from the area shown hatched on the attached site plan.

.5 Ensure contaminated waste material removed from the premises is carted in vehicles for which an Environment Protection Authority permit to transport waste is in force.
.6 Ensure contaminated waste material referred to in requirement 5 is disposed at a site licensed under the Environment Protection Act 1970 to receive such material.
-7 East load of contaminated waste material shall be accompanied by an Environment Protection Authority transport certificate.
-8 Ensure disturbed lead contaminated soil on the premises remains covered except for when excavation or soil movement to comply with requirements 1, 2 and 5 are in progress.
.9 Use your best endeavours to ensure soil or dust is not able to leave the premises under the effects of wind."
7.6 EPA Preliminary advice to Council
EPA officers have indicated at meetings of Council ' s Project Team that a tentative initial testing grid for sampling would be one bore site within a 20m grid across the site. This would result in approximately 90 sites and samples. The depth of bore samples would vary however the EPA have also advised would need to be of sufficient depth to strike clean fill.
7.7 Ground Water Information
Advice from Andrew Shugg of the Water Resources Management Section indicates the following:-
0 Thousands of bores for ground water were sunk in the metropolitan area during the drought years of 1867, 68 and 1982, 83. There was no requirement for registration of the bores at these times so no information has been recorded for the bores.

0 Andrew Shugg could quote rudimentary information for only a few bores around the "Merindah Avenue" land, the same information as previously forwarded by Frank Cox of the Rural Water Commission.
0 In reference to the question of movement of lead in the soil; the rate of movement in sandy aquifers is slow, at around 30 metres per year. Movement of lead through high clay soils is much less; lead levels ten metres from the point of contamination can be at background levels due to attenuation on the lead by the clay (cation attraction of the lead of the clay). The 1976 report from A S James Pty Ltd shows there are generally clays between 2.5 metres below ground level over the Merindah Avenue site.
Refer to Appendix 3.
7.8 Identification of Bores in Area
.1 From the advice available about the possibility of many unregistered bores sunk prior to requirements for registration under the Groundwater Act, it is not possible to identify all the bore sites from official records. Local knowledge of the way bores were sunk over the last twenty years also suggests that there may be many unrecorded bores in the area. The lessee of the Municipal Golf Course related his recollection of bores being put down fairly easily by local contractors doing landscaping/gardening works in Sandringham. The sandy soils of the area and the water table being 5-15 metres below ground level makes this possible.
.2 Identification is probably only possible through survey of each property within the vicinity of the Merindah Avenue land.
.3 A follow-up report of a bore on the property of "Halycon Protein" George Street, Sandringham (south east corner of Wangara Road) confirms that a bore was used €or watering of gardens and for circulation through their cooling tower until the bore "dried up" a few years ago.

8. CONCLUSIONS
8.1 Site Tests
Testing of the site has been limited although there have been 3 different tests carried out, neither has comprehensively covered the whole site:-
.1 Pacific Dunlop investigations report included eight test locations along the western boundary of the Dunlop site and southern end of the Merindah Avenue land. These locations were chosen to coincide with known dumping areas. The tests indicate levels of lead contamination, ph levels and depth of fill.
.2 A S James report for Council of the Merindah Avenue land which indicates the extent of fill. Locations tend to be along the western side of the site area.

8.2 Extent of fill
.1 The A S James report indicates the deepest excavations and fill occurring in the southern half of the site from about .8m to 4.2m in depth. The Pak-Poy tests gives some confirmation of this trend however the nature of the tests may not have been directed towards determining the extent of fill. The test bores were more shallow and for locations P.19, P.22 & (2.39, areas which were deeply excavated, the tests result indicate no fill. These results may also reflect the type of back fill used in the site as the evidence submitted does refer to the use of excavated sands and soils from Beaumaris and Sandringham street constructions for back fill and top-dressing of the old tip.
.2 There does appear some surface fill along the northern boundary of the site along Holloway Road.
8.3 Development & Use of Pacific Dunlop site
-1 The western factory building (now demolished) was the main building used for the manufacturing processes involving lead oxide hence the levels of contamination found on the site. The lead oxide tower and sludge settlement ponds were situated in the south western corner of the Pacific Dunlop site. Barrels were also stored and handled in this location which could have implications off site.
.2 The northern portion of the former Dunlop site would have been more affected through the settlement ponds for neutralised acid which were situated there and through the drainage of the site to the northern area which was previously a swamp. This in turn may also have had off-site implications affecting the Council owned land through the seepage of acid in the soil.
.3 The Pak-Poy report tests indicate contamination at all test sites although the sites with the highest results coincide with the areas used for tipping. The tests results are inconclusive for an assessment of the whole site but do indicate the highest levels occurring at the surface (0-lOcm) reducing dramatically on the depth increases. The one exception is location P.21 which shows extremely high levels of lead contamination though the whole sample bore from surface to subsoil (0-50m). The sample site at location P.18 also indicates contamination through the whole sample although of no comparison to the former location. These two locations are the only ones with elevated levels below 30cm.
.4 Further advice is needed on the chemical analysis of the bore samples and the significance of contamination evident in the test results.

8.4 Merindah Avenue & Green Belt land
.1 Prior to 1948 the area of land known as "Grants Pit" which included what is known as Merindah Avenue land and the south-east part of the Green Belt was used for sand extraction. The remainder of the Green Belt and the former Pacific Dunlop site was used for market gardening. The surrounding area was vacant scrub, market gardens and the beginning of residential subdivision and development.
.2 This area was used for tipping by Council from 1948 to 1955 (at the most). It appears that sand extraction continued in the early part of this period. In the latter phase whilst formal use by Council ceased there may have been informal public use of the area whilst it was gradually being backfilled, levelled and revegetated.
.3 During this time the area was used as a tip by Council and the general public. There is clear evidence that the tip was used by the Dunlop battery manufacturing plant.
.4 Based upon evidence presented Dunlop dumped hard waste which may have contained solid lead. Although evidence by residents refers to sludge and various forms of waste.
.5 Dunlop's use of the tip seems confined to the southern end of the Merindah Avenue and Green Belt Reserve land and along the western boundary of the Dunlop site. Reference is often made to dumping at the mid-point along Dunlop's western factory.
.6 The section of the Green Belt running along the southern boundary of Dunlop was used for car parking and hard material was deposited in this area to consolidate the access and parking surface. The hard material comprised broken hard rubber battery cases and plastic battery caps. This area was transferred to Council for public open space in the 1960's.
.7 Davies refers to a "well midway" between the existing bonfire scar on the Merindah Avenue land and the existing Scout Hall building.
.a Dunlop used their own land in the northern section for settlement of neutralised acid and waste which could also have effected the Council land.
.9 The location of sludge and settlement tanks and storage area for barrels in the southern western corner of the Dunlop site also had potential for localised off-site contamination through spillage.

8.4 Merindah Avenue & Green Belt land (cont'd)
.10 It has become clear from the evidence produced that the northern half of the land including the Scout Hall was not used extensively for tipping or land fill and as such is unlikely to be contamined.
.11 Having regard to the evidence of the use of the land it is recommended that any site investigations recognise the variation in the use and development and consequently its potential for contamination. In this respect the northern half of the site was little affected by sand excavation and tipping and is unlikely to be severely contaminated. The southern half however coincides with the main and deepest areas of excavation and tip fill and probably has greatest potential for contamination. The area of the "Green Belt" adjoining to the south of the former Dunlop site was not used for excavation or tipping. The only likely affect would have been through surface contamination by dust and crushed hard materials that were deposited to stabilize the surface of the car parking areas.

1. INTRODUCTION
Consulting Environmental Engineers Pty Ltd (CEE) was engaged by the City of Sandringham to undertake an environmental assessment of the northern half of an area od Council land known as the "Merindah Avenue" land.
The "Merindah Avenue" land is located in Sandringham between Holloway Road to the north and Spring Street to the south. The Green Belt urban forest reserve, which comprises mature trees, shrubs and garden beds, forms the eastern boundary of the site behind which is located the decommissioned and partly demolished former Dunlop Sandringham Battery Plant. 5esidential properties on the eastern side of Cooke Street form the western border of the "Merindah Avenue" land. To the north, across Holloway Road is the Sandringham Technical School.
The site itself is a rectangular area of approximate dimensions, 70 by 300 metres, grassed and essentially flat. Only the northern section of the land, designated Stage 1 and approximately 60 by 160 metres, was included in this site assessment. The land and the area included in the survey is shown in Figure 1.
As detailed in a report compiled by Council officers (Site Assessment Report on the Use of "Merindah Avenue" Land and Green Belt Reserve, Sandringham, August 1990), sections of the land (mainly in the southern half) had previously been used for sand extraction and for the disposal of municipal refuse and clean fill.
Previous investigations of the former Dunlop Battery Plant site confirmed that sections of that site had been heavily .contaminated with lead and antimony, and that this contamination apparently extended onto some adjoining areas including sections of the (Council owned) Green Belt which separates the subject land from the former Dunlop site.
This report outIines the objectives and scope of the sampling programme and presents results from the site investigation. The analytical results obtained are compared with appropriate contamination criteria.

OBJECTIVES AND SCOPE OF INVESTIGATION
The objective of the investigation was to evaluate the environmental condition of the northern half of the "Merindah Avenue" land, particularly in relation to the presence and potential extent of any contamination of soil.
The scope of the field work was based on recommendations made in the following site reports which have previously been prepared for the Council:
* Assessment of Environmental Condition of Merindah Avenue Land, Consulting Environmental Engineers, April 1991.
* Merindah Avenue Site: Environmental Review Study AGC Woodward-Clyde,
June 1992. 4
The scope of work is summarized below:
* a "walkover" inspection of the site to identify areas which may be indicative of anomalous soil conditions possibly the result of contamination;
* the collection of soil samples from the surface and at depth, at selected locations across the site based on a regular grid and on the findings of the inspection;
* a programme of laboratory analysis of each of the samples collected for the parameters detailed below; and
* preparation of this report.
The investigation was designed to address the range of contaminants assessed as having some potential to be present on the land. The principal means by which contamination could reach the site were perceived to be the following:
* particlulate fall-out from the former Pacific Dunlop Battery Plant near the eastern boundary of the site;
* surface water runoff;
* dumping of contaminated fill;
* dumping of contaminated waste; and
* contamination from the previous landfill operation on the southern section of the land.
Consulting hnvlmrunental Engineers 72 of 185 ENVIRONMENTAL ASSESSMENT OF "MERINDAH AVENUE" LAND 3
Based on the potential sources of contamination the following analytical programme was developed for soils collected from the site:
* Heavy Metals (Lead, Copper, Nickel, Chromium, Arsenic, Cadmium, Zinc and Antimony);
* Extractable Organo Halogens (EOX); and
* Total Petroleum Hydrocarbons (TPH).
The above parameters do not represent an exhaustive set of possible contaminants. They are, however, representative of contaminant groups which exhibit a high level of environmental persistence and, in some cases, toxicity. .* The EOX parameter is a sensitive screening technique for organo-halogens. This method is designed to detect the presence of a range of organochlorinated compounds such as chlorinated insecticides, herbicides and polychlorinated biphenyls (PCB's). However, it is not able to identify the specific compounds contributing EOX values. The use of EOX provides a cost effective screening method suitable for sites that have no known history of use of organochlorines yet some potential to have organochlorine present as soil contaminants.
3. FIELD INVESTIGATION
Site field work was conducted on the 16 September 1992 under the supervision of an engineering geologist.
3.1 Site Inspection A "walkover" inspection of the site was conducted before sampling commenced. The site is of essentially low relief with a thick covering of mowed grass, but is otherwise devoid of notable features. The site currently serves as undeveloped, open reserve land with unrestricted access by the public.
No visual signs of contamination were noted on the site.
The area under investigation was approximately 60 x 160 m.
3.2 Soil Sampling A programme of soil sampling was carried out using a backhoe (supplied by the City of Sandringham) to excavate pits at selected locations across the site. Pit locations were based on a regular 20 metre grid pattern, set out using a tape measure to define grid spacings and the distance from established boundaries.
Consulting Emnvirorunental Engfneers 73 of 185 ENVIRONMENTAL ASSESSMENT OF "MERINDAH AVENUE" LAND 4
Each pit was excavated to a depth of 0.5 m or to the base of any fill profile where fill was encountered. The exposed soil profiles were logged by the supervising geologist and the presence of any groundwater was noted. Soil samples were collected from the surface (0.0 to 0.15 m), from a depth of approximately 0.5 m, and where fill depths exceeded 1.0 m, samples were taken from the base of the fill.
A total of 21 pits were excavated to depths ranging from 0.6 to 1.5 m. A total of forty four samples designated BS 1 to Bs 44 were collected comprising two samples from each pit, a quality assurance/quality control (QA/QC) duplicate and a sample collected off-site (immediately north of Holloway Road as shown in Fig 1) to establish background conditions.
Samples were collected and preserved according to stric:, Environment Protection Authority (EPA) approved procedures which included the decontamination of all sampling equipment prior to and between each sampling event to minimize the potential for cross-contamination. Only soil which had not come into direct contact with the backhoe bucket was sampled.
All soil samples were placed into laboratory-certified clean, 500 ml glass jars and put into temporary cold storage in the field using portable ice chests with ice.
3.3 soil Analysis Twenty eight samples comprising all surface samples, seven of the deeper samples, the QA/QC duplicate and the background were selected for analysis and promptly conveyed to the appropriate analytical laboratory in accordance with Woodward-Clyde chain of custody procedures.
The locations of the sampling pits are shown in Figure 1, while detailed logs of soil profiles indicating sampled intervals are included in Appendix 1.
4. RESULTS
4.1 Site Geology Generally, the soil profiles encountered in the pits consisted of 0.2 to 0.3 m of imported topsoil, comprising grey silty sand overlaying light brown and grey silty and clayey sands. The sands tended to increase in clay content with depth, and in Pits 13, 16, 18, 19, 20 and 21 graded into sandy clay. Slow groundwater seepage was observed in twelve of the pits between 0.8 and 1.1 m depth, probably as a result of perched water contained above the more clayey sediments.
Consulting EmnvlmNnental Engineers 74 of 185 ENVIRONMENTAL ASSESSMENT OF "MERINDAH AVENUE" LAND 5
Pits 2, 3, 15 and 16 encountered fill containing refuse to depths of 1, 0.6, 1.1 and 1.3 m, respectively. This fill material consisted of a mixture of silty sand and general refuse (including animal bones, minor plastics, bricks, concrete and metal pipes). The imported fill encountered in the remaining 17 pits did not show any visible evidence of refuse.
4.2 Results of Analytical Programme
4.2.1 Contamination Criteria. Table 1 summarizes the results of the soil analyses, while full laboratory analytical reports are presented in Appendix 2.
There are currently no statutory acceptable levels for industrial contaminants in soils in Victoria. The EPA favours the determination of acceptable levels on a site specific basis. I?
The current practice in the evaluation of a site for soil contamination is to utilize guidelines recommended by the Australian and New Zealand Environment and Conservation Council (ANZECC) and National Health and Medical Research Council (NHMRC). ANZECC and NHMRC provide two soil quality criteria, A and B levels, as guide-line values for a range of contaminants. The "A" level is defined as the "normal" background level and the "B" level is defined as the investigation level which can be used to assess whether soil conditions warrant further investigation. The "A" criteria are presented as ranges and the "B" criteria as limit values for investigation. Where ANZECC and NHMRC have not provided A and B levels, the Dutch criteria are recommended for use as interim values.
The appropriate contaminant limits, where available, are included in Table 1.
4.2.2 EOX. Laboratory analysis for EOX was conducted on the thirty soil samples collected.
The EOX concentrations in all samples from the site ranged from e0.02 mgCl/kg (BS 32) to 0.42 mgCl/kg (BS 211, while the background sample analysed had an EOX value of 0.15 mgCl/kg.. These values fall within the range of background results collected from other sites in the Melbourne metropolitan area (Woodward- Clyde, pers corn).
4.2.3 Total Petroleum Hydrocarbons. Laboratory analyses for Total Petroleum Hydrocarbons (TPH) were carried out on 30 of the samples.
Concentration of TPH were below detection limits for all samples analysed.
Consulting Emnvironmental Engineers 75 of 185 ENVIRONMENTAL ASSESSMENT OF "MERINDAH AVENUE" LAND 6
4.2.4 Metals. The following is a summary of the analyses results for the metals.
Arsenic was detected in a total of 12 of the samples analysed with concentrations ranging from 2.2 to 24 mg/kg dry weight. The ANZECC "B" value for arsenic, set at 20 mg/kg, was thus exceeded by surface sample BS 31, collected from Pit 16.
Cadmium was not detected in any of the samples analysed.
Chromium was detected in two samples, both well below the ANZECC "Brr level of 50 mg/kg.
Copper was detected in five of the samples anaiysed, all of which were well below the ANZECC "B" level of 60 mg/kg.
Nickel was detected in five samples, all below the ANZECC "B" level of 60 mg/kg.
Lead was detected in a total of 21. Only sample BS 37 (360 mg/l), a surface sample from Pit 19, reported a concentration above the ANZECC "B" limit of 300 mg/kg. Sample BS 38, a field duplicate of BS 37 reported a concentration of 480 mg/kg. Given the heterogeneity of the soil matrix and the likely uneven distribution of contaminants in that matrix, these concentration values for the duplicate samples are considered adequate.
Antimony was recorded in 4 samples, all below the ANZECC "B" level of 20 mg/kg. Samples where antimony was detected were associated with elevated lead concentrations.
Zinc was recorded in fifteen of the samples analysed. The concentrations recorded exceed the ANZECC "B" level (200 mg/kg) in samples BS 30 (420 mg/kg) taken from 1 metres depth in Pit 15, in fill, and BS 40 (360 mg/l), a surface sample from Pit 20. The other samples were well below the ANZECC "B" limit.
5. CONCLUSIONS
A site investigation was carried out for the Stage 1 area of the "Merindah Avenue" land, which involved a programme of site inspection, soil sampling and analysis for a range of contaminants assessed as having potential to be present on the site, as a result of the proximity of the former Dunlop Battery Factory site and the known history of refuse disposal on sections of the "Merindah Avenue" land.
Consulting Gnnvironmental Engineers 76 of 185 ENVIRONMENTAL ASSESSMENT OF "MERINDAH AVENUE" LAND 7
The results of the investigation of the Stage 1 area may be summarized as follows:
1. the majority of the area appears to have been filled to a depth of between 0.2 and 0.3 m with "clean" topsoil (ie topsoil which is essentially free of contaminants);
2. small-scale refuse disposal (to a depth of only about one metre) appears to have occurred in a few discrete locations (for example, in the vicinity of Pits 2 and 3, and Pits 15 and 16);
3. of the 232 individual analytical results for heavy metals in the soil samples, all but five were either below the threshold of detection or less than the respective ANZECC B criteria; l?
4. the five heavy metal results which exceeded the ANZECC B criteria all did so by relatively small margins - four of these were for surface samples from near the southern end of the Stage 1 site (Pits 16, 19 and 20) and one was for a 1 m deep sample from Pit 16 (in fill containing refuse);
5. all of the EOX analytical results were within the normal range of background values (for total organochlorinated compounds) in the Melbourne metropolitan area;
6. petroleum hydrocarbons were not detected in any of the samples.
6. LIMITATIONS
The findings outlined in this report are based on data from the indicated investigation and sampling sites and based on the specific analytical programme. Soil samples collected may not be representative of all conditions across the site. Inferences about the nature and the continuity of the soil away from the soil sampling points are made, but cannot be guaranteed.
This report has been prepared for the particular investigation described and no responsibility is accepted for the use of any part of this report in other contexts or for any other purpose.

Tliis work is required so that preparation of a Certificate or Statement of Environmental Audit may be considered for either part or the whole of the site depending on the results of the investigation. Tlie "Merindah Avenue" land is located in the City of Sandringham between Holloway Road to the north and Spring Street to the south. Residential properties are located directly to the west of the site which is also bordered to the east by a Green Belt urban forest reserve. On the eastern border of the Green Belt is the decommissioned and partly demolished former Dunlop Battery Plant. The entire site is a rectangular area of approximate dimensions, 70 by 300 metres, grassed and essentially flat. The Green Belt Reserve together with the southern section of the land, designated Stage 2, was included in this site assessment. The land and the area included in this assessment is shown in Figure 1. A number of reports have already been issued regarding this site and its proximity i. to the former Dunlop Plant. These reports include: "Soils Investigation: Sandringham Battery Plant", Pak-Poy and Kneebone Pty Ltd/CSIRO, September 1988. "Site Assessment Report on the Use of "Merindah Avenue" Land and "Green Belt" Reserve Sandringham", City of Sandringham, August 1990. "Assessment of Environmental Condition of Merindah Avenue Land", Consulting Environmental Engineers, April 1991. "Merindah Avenue Site Environmental Review Study", AGC Woodward- Clyde, June 1992. "Environmental Assessment of "Merindah Avenue" Land Stage l", Consulting Environmental Engineers, December 1992. 1-1 117 of 185 ...... These reports have all iiivestigated the extent of site contamination associated with the tipping of municipal refuse together with the disposal of solid and liquid wastes from tlie former Duiilop Batteiy Plant iiito excavated sand pits which were present iiiaiiily in the southern sectioii of the "Meriiidali Avenue" site. The northern part of the site was investigated in the report compiled by CEE in December 1992 for the City of Sandringham. This report concluded that tlie northern portion of the site appeared to contain low levels of contaminants associated with previous site activities. This work described in this report is consistent with the recommendations contained in the June 1992 AGC Woodward-Clyde report which detailed the investigations required to enable certification of the site to proceed. 1-2 118 of 185 ...... ___- ~~~ 2.0 OBJECTIVES AND SCOPE OF INVESTIGATION The objective of this investigation was to evaluate the environmental condition of the southern lialf of tlie "Merindah Avenue" land and the Green Belt Reserve, particularly in relation to tlie presence and potential extent of any contamination of soil. The scope of the field work was based on recommendations made in the 1992 report by AGC Woodward-Clyde and mentioned in Section 1 of this report. The scope of work is summarised below: a collection of soil samples from the surface and at depth, at selected locations across the southern portion of the site and theGreen Belt Reserve based on a grid system; the installation of three groundwater monitoring bores across the southern portion of the site to enable samples of groundwater to be collected; 0 a soil gas survey to check for the presence of methane (a major component of landfill gas); a program of laboratory analysis of discrete and composite soil samples together with groundwater samples for selected parameters, and; 0 preparation of this report. *. The investigation was designed to address the range of contaminants assessed as having some potential to be present on the land. The principal means by which contamination could reach the site were perceived to be the following: particulate fall-out from the former Pacific Dunlop Battery Plant near the eastern boundary of the site; 0 surface water runoff; 0 dumping of contaminated fill; 0 dumping of contaminated waste, and; 0 soil and groundwater contamination from the previous landfill operation on the southern of tile site. 2-1 119 of 185 ... . Based 011 the potential sources of coiltamination the following analytical program was developed for soils collected from the site: 0 Heavy Metals (Lead, Cadmium, Nickel, Chromium, Copper, Zinc, Arsenic, Antimony, Cobalt and Mercury); 0 Extractable Organo Halogens (EOX), and; e Total Petroleum Hydrocarbons (TPH), Total Cyanide, Poly-aromatic Hydrocarbons (PAH's), pH and Electro-conductivity (EC). In addition, groundwater samples were analysed for a range of landfill leachate parameters consisting of the following: b Calcium, Magnesium, Sodium, Potassium, Total Alkalinity as CaCO,, Bicarbonate Alkalinity as CO,, Carbonate Alkalinity as CO,, Total Dissolved Solids, Biochemical Oxygen Demand (BOD5), Sulphate and Chloride; 0 Nitrate Nitrogen, Ammonia Nitrogen, Organic Nitrogen, Total Phosphorous, Chemical Oxygen Demand (COD), Total Organic Carbon (TOC) and Phenolic Compounds, and; Heavy Metals (Cadmium, Chromium, Lead, Copper, Zinc, Iron, Arsenic and Mercury). The above parameters do not represent an exhaustive set of possible i. contaminants. They are, however, representative of contaminant groups which exhibit a high level of environmental persistence and, in some cases, toxicity. It is worth noting that EOX is a sensitive screening technique for organo-halogens which is designed to detect the presence of a range of organo-chlorinated compounds such as chlorinated insecticides, herbicides and poly-chlorinated biphenyls (PCB's). However, it is not able to identify the specific compounds contributing EOX values and provides a cost effective screening method suitable for sites that have no known history of use of organo-chlorines yet some potential to have organo-clilorine present as soil contaminants. 2-2 120 of 185 3.0 FIELD INVESTIGATION Site field work was carried out on the 25 April 1993. Soil sampling was carried out under the supervision of an experienced environmental engineer and the groundwater nionitoring bore installation was carried out under the supervision of an experienced hydrogeologist. 3.1 SOIL SAMPLING A program of soil sampling was carried out using a backhoe (supplied by the City of Sandringham) to excavate pits at selected locations across the site. Pit locations were based on a 40 metre grid pattern across the southern portion of the "Merindah Avenue" site and at approximate equal spacings across the length of the Green Belt. A tape measure was use to define grid spacings and the distance from established boundaries. The sampling pits are shown in Figure 1 and pit logs are shown in Appendix 1. Each pit was excavated through fill (if encountered) to where natural soil appeared to be. The exposed soil profiles were logged by the supervising environmental engineer and the presence of any groundwater was noted. Soil samples were collected from the following depth intervals (deeper samples taken 3 . if applicable): 0 0.0-0.3m; 0 0.3-0.6m; 0 0.6-1.0m; 0 1.0-2.0m, and; 0 2.0-3.0m. A total of 18 pits were excavated to depths ranging from 1.5m to 3.lm. A total of 80 soil samples were collected and designated, for example, 22.1 with "22" designating the pit number and "1" designating the first depth interval. 3- 1 121 of 185 Samples were collected arid preseived according to strict Environment Protection Au tliority (EPA) approved procedures wliich include tlie decoiitaminatiori of all saiiipling equipment prior to arid behveeri each sampling event to iniriiniise the potential for cross-containination. Only soil wliich had not come into direct contact with tlie backhoe bucket was sampled. All soil samples were placed into laboratory-certified dean, 500ml glass jars and put into temporary cold storage in the field using portable ice chests with ice. 3.2 SOIL ANALYSIS The southern portion of the "Merindah Avenue" site was divided up into three separate grids containing four sampling locations. The Green Belt reserve was divided up into two separate grids containing three sampling locations. This is shown in Figure 1. Each sampling interval within the grid was composited to form one soil sample for laboratory analysis. This information is summarised in Table 1. In addition, selected discrete soil samples were also analysed dependent on observations made in the field. To obtain the composite sample, the soil was thoroughly mixed in a steel mixing bowl before' placing in certified-clean glassware as before. A total of nine discrete samples were sent to the Australian Centre for Water Treatment and Water Quality Research in South Australia for EOX analysis. A total of twenty five composite. samples (including two duplicate samples taken for Quality Assurance/Quality Control) and nine discrete samples were sent to Applied Environmental Services (AES) for the remaining soil analyses as detailed in Section 2 of this report. 33 GROUNDWATER MONITORING BORE INSTALLATION Drilling of borelioIes at the site was performed using hollow flight augers. Drilling was undertaken by L.A. & L.J. Turnbull Pty Ltd of Pascoe Vale, Victoria. 3-2 122 of 185 All boreholes drilled for the installation of groundwater monitoring bores were logged by a hydrogeologist. Drilling and bore construction details are suminarised in Table 2 arid documented oil a log construction proforma iiicluded in Apperidix 2. All bores were completed for loiig term groundwater monitoring purposes using the followirig materials: b 50mm diameter Class 12, threaded uPVC casing with machine slotted screen sections; bottom plugs were permanently attached with stainless steel rivets; b filter pack sand (2mm to 3mm washed silica sand); 4 bentonite pellets; b bore cuttings mixture for annulus backfilling, and; b 150mm diameter steel GATIC covers, mounted flush with the ground surface. All monitoring bore construction materials were new and undamaged. No glues or cements were used to construct any groundwater monitoring bores installed for this investigation. The groundwater monitoring bores were all drilled to a depth of 10 metres below ground surface level. The following procedures were followed for the installation ;. of groundwater monitoring bores once the total depth of the borehole was reached:. 4 the total depth of the completed borehole was measured with a weighted tape measure; b the uPVC screen, blank sections, end cap and surface cap were assembled and lowered into the borehole; filter material was slowly added to the borehole annulus from the base of the PVC casing to 0.5m above the top of the screen slots; a seal of bentonite pellets approximately 0.5 m thick was installed above the filter material; 4 the remaining space within the borehole annulus was backfilled to approximately 0.5m below ground surface with bore cuttings, and; 3-3 123 of 185 ...... b a 15011~11idiameter steel GATIC cover was niounted flush with tlie ground and concteted up to tlie ground surface. 3.3.1 Groundwater Monitoriiig - Purging and Development of Bores Bore development was undertaken to achieve stable physical and chemical groundwater conditions that are typical of tlie aquifer at each of the bore locatjons. Following bore installation each bore was bailed dry using a teflon bailer. Due to the low transmissivity of the aquifer the bores were then left overnight before sampling. 33.2 Groundwater Levels Groundwater levels were measured from the top of the uPVC casing using an electronic water level probe and recorded in field logbooks. This data is also presented in Table 2. 33.2 Monitoring Bore Surveying All groundwater monitoring bores were surveyed by J.R.L. Neil Services Pty Ltd. Surveying included measuring the elevation of the top of the uPVC casing with . the cap removed, the natural ground surface at the bore location and the coordinate location of the uPVC casing. Elevation data were reported in metres, Australian Height Datum (AHD), and the coordinate data in metres, Australian Map Grid (AMG). This data is shown in Appendix 3. 3.4 GROUNDWATER SAMPLING All groundwater sampling equipment was decontaminated with a cleansing agent (Decon 90) and rinsed with potable water prior to sampling each bore. A teflon bailer was used to collect the groundwater from'each bore. 3-4 124 of 185 Groundwater was placed immediately into certified-clean glass coiitaiiiers aiid iiniiiediately preseived (if applicable) depending oil the actual required analyses.' All saiiiple coiitaiiiers were tightly capped, labelled wit11 a unique sample ideiitilicatioii iiuiiiber, recorded on a chain of custody proforrna and stored in an ice chest with ice. During bore sampling, further water was collected to measure the following chemical parameters at the time of sampling: 0 pH; 0 electro-conductivity (EC); 0 dissolved oxygen; 0 temperature, and; 0 redox potential. Table 3 contains the field parameter data recorded for the groundwater samples collected during the investigation. I 3.4.1 Groundwater Analyses A total of three groundwater samples were sent to the iATA-accredited EML (Chem) Pty Ltd in Surrey Hills, Victoria for the laboratory analyses listed in Section 2. A chain of custody record was utilised by field personnel to document possession of all samples collected for chemical analysis from the time of collection to receipt by the analytical laboratory. 3-5 125 of 185 . 4.0 RESULTS 4.1 smGEOLOGY AND HYDROGEOLOGY The geology of the site consists of the Brighton Group-Fyansford formation that domiiiates the south and south-eastern region of Melbourne. In general, the sliallower Brighton sequence is made up of fine to coarse sands, with minor poorly sorted and poorly consolidated gravels. The borelogs presented in Appendix 1 show the shallow underlying geology consistent with the Brighton Group. It is worth noting that a possible shallower perched water table exists as a shallow moisture region was observed in two bores during drilling and water seepage was observed in two excavation pits. This shallow water table is probably seasonal. The shallow groundwater most probably is the result of rainwater infiltration ponding on the clay layers within the sands. Although the deeper groundwater at this site appears to flow in a north-west to south-east direction, the expected groundwater flow patterns in this region are north-east to south-west (ie towards Port Phillip Bay). 4.2 RESULTS OF ANALYTICAL PROGRAM 4.2.1 Contamination Criteria. Table 4 summarises the results of the soil analyses and Table 5 summarises the results of the water analyses. Full laboratory certificates are presented in Appendix 4. TIie assessment of the results of the soil samples is based on the "Environmental Investigation" guidelines in the ANZECC (Australian and New Zealand Environment and Conservation Council) and NHMRC (National Health and Medical Research Council), 1992 "Guidelines for the Assessment and Management of contaminated Sites", as well as' Ministerial Direction No 1, dated May 1992, and relevant guidelines promulgated by the Environment Protection Authority of Victoria (EPAV). For the cliemicals not listed or for which no 4-1 126 of 185 . .__ .. investigation level is listed, it is proposed by tlie ANZECC and NHMRC guidelines, that tlie "Diitcli B" level be utilised as an iiivestigation tliresliold. l'liese are the. recogiiised EPAV criteria for the assessnierit of contaminated sites and tlie EPAV teiid to accept these values as indicative of soil quality suitable for serisitive land uses. As a basis to assess the coniposite soil sample results, the investigation leveI was divided by the number of individual samples that comprised each composite sample to give an "adjusted" investigation criteria level. For the assessment of tlie results of water analyses, potable water limits have been used as the sliallow water table may have some potential for (for example) garden watering in residential areas. The potable water limits have been taken from the National Water Quality Management Strategy, 1992, "Australian Water Quality Guidelines for Fresh and Marine Waters" and from the EPAV, 1983 Publication, "Recommended Water Quality Criteria". 4.2.2 EOX There are no recommended guideline values for EOX analysis so the results from the Stage 1 investigation have been used to note higher than expected values. Laboratory analyses were conducted on nine discrete samples. The results ranged from ~0.03mgCl/kg (sample 37.2) to 1.96 mgCVkg (sample 28.3). A background sample collected in the Stage 1 investigation exhibited an EOX value of 0.15 mgCl/kg and this value is again used as background reference criteria. The results indicate: a total of seven of the nine samples are around background levels with sample 28.3 exhibiting an EOX value of over ten times above the expected background level and sample 28.4 exhibiting an EOX value five times above the expected background level. It is worth noting that neither sample 28.3 nor 28.4 exhibited high levels of any other soil contaminant tested for in this investigation. 4-2 127 of 185 4.2.3 Tolnl I’elroleum Hydrocarbons (TPI-I) Laboratory analysis for TPH was carried out 011 25 composite and nine discrete soil saiiiples. The results indicate: 0 oiie sample, COMP 25, exhibited a TPH value marginally above the adjusted investigation criteria. 4.2.4 Metals Laboratory analysis for metals was carried out on twenty five composite samples and nine discrete samples. ”lie results indicate: arsenic was detected above the ANZECC B criteria in one discrete sample and the adjusted criteria in one composite sample; cadmium was detected above ANZECC B criteria in two discrete samples; cobalt was not detected above ANZECC B criteria in any sample; chromium was detected above ANZECC B criteria in four discrete samples and above the adjusted criteria in one composite sample; copper was detected above ANZECC B criteria in two discrete samples and above the adjusted criteria in three composite samples; mercury was not detected above ANZECC B criteria in any sample; nickel was detected above ANZECC B criteria in four discrete samples and above the adjusted criteria in one composite sample; lead was detected above ANZECC B criteria in five discrete samples and above the adjusted criteria in seven composite samples; antimony was detected above the adjusted criteria in one composite sample, and; zinc was detected above the ANZECC B criteria in two discrete samples and above the adjusted criteria in seven composite samples. Total Cyanide Laboratory analysis for total cyanide was carried out on twenty five composite samples and nine discrete soil samples. No sairiple exhibited a total cyanide value above further investigation level. 4-3 128 of 185 4.2.6 Polynroniatic I-iydrocarbons (PAH's) Laboratory analysis for PAIl's was carried out 011 nine discrete samples. No sample exceeded the further investigatioii level for Total PAH's. It is worth noting, however, that one sample, 29.4, exhibited a level of Benzo (a) pyrene inargiiially above the ANZECC further investigatioii level. 4.2.7 Groundwater Analyses Laboratory analysis was performed on a groundwater sample from each of the three bores installed. The results indicate that two groundwater samples are very similar but one sample, MB2, exhibits an unusually high salinity (TDS) value of 4400mg/L. This value is five times above the expected salinity value in this region. According to Leonard', salinity values should range around 1000 mg/L in this area which can be seen in the results from both MB1 and MB3. Much higher salinity values are not unheard of but due to MBl's proximity to the two other bores this could represent a source of increased salinity due to the landfill. With reference to Table 5 and the Piper Diagram shown in Figure 2, the increased salinity is almost all due to high sodium and chloride values. Again this could be due to natural conditions but this does seem unlikely from this set of results. . It is also noted that an unusually high Chemical Oxygen Demand (COD) was encountered in sample MB2, .which is likely to be associated with the salinity of the groundwater. The source of the higher than expected salinity in sample MB2 is not known, but is though to be either naturally occurring, due to the presence of the former landfill, or is the result of an off-site effect. The piper diagram (Figure 2) indicates, however, that all three samples of groundwater have similar chemistry. 4-4 129 of 185 111 term of the groundwater quality compared to potabIe limits, MBl and MB3 both exhibit parameters within potable limits except for the levels of irori in both samples which sliglitly exceed criteria. The sample MB2 exceeds the potable criteria for sodium, TDS, chloride, ammonia-nitrogen arid copper. 4.2.8 Soil Gas Survey A soil gas survey was carried out to check for the presence of Iandfiil gas associated with the previous waste disposal carried out at the site. An explosimeter was used to detect the presence of methane. A total of six locations around the site were assessed for landfill gas (see Figure 1). No reading was measured on the explosimeter at any location. 43 IMPLICATIONS OF SOIL MATERIAL, SOIL ANALYSES AND GROUNDWATER ANALYS ES From' the pit excavations it is apparent that much larger amounts of fill material exist over the Stage 2 area of the "Merindah Avenue" site than were observed in the Stage 1 investigation on the northern half of the site. The depth of fill extends to 2.8m at its deepest point in the excavated pits. No landfill gas was detected at six locations around the site using an explosheter. This is consistent with the age of the landfill and the main fill constituents being solid, inert waste. No putrescible matter was observed during the Stage 2 investigation. It is also worth noting that as the soil within the fill was predominantly sand, any landfill gas would probably be released to the atmosphere rather than build up over time. It is also apparent that the predominantly heavy metal contamination is widespread throughout the fill in the Stage 2 area, and levels of contaminants in excess of ANZECC investigation criteria were recorded at varying depths tlirougliout the fill. The majority of the identified contamination was found to exist in the middle and southern parts of the Stage 2 "Merindah Avenue" site, and is expected due to the larger amounts of' fill in these areas. However, coiitainiiiaiits were also observed in samples taken from the Green Belt Reserve and from the northern part of the Stage 2 area. 4-5 130 of 185 From the levels of contaiiiinants detected it appears that clean-up of the Stage 2 section of the site would be required for any Certificate to be issued (for the Stage 2 area). Tlie volume oE soil requiring removal could be in excess of 10,000 toiines, wliicli would involve a cost of $0.50 to $0.75 million. For these reasons, it may not be economically viable for Council to seek a Certificate of Environmental Audit for the Stage 2 area. Tlie site could either be kept at its present non-sensitive land use, or alternatively redeveloped for an appropriate industrial, community or commercial land use (as discussed below). 4-6 131 of 185 .. .. 5.0 CONCLUSIONS An enviroiiiiiental site assessment has been carried for the Stage 2 area of the "Merindah Avenue'' site in Sandringham. A programme of pit inspection, soil sampling, a soil gas survey, groundwater monitoring bore installation and groundwater sampling has been carried out. This programme was required to investigate the potential for a wide range of contaminants to be present in the soil and groundwater as a result of the proximity of the site to the former Dunlop Battery Factory site and the known history of uncontrolIed refuse disposal on sections of the "Merindah Avenue" site. The results of the investigation of the Stage 2 area may be summarised as follows: 0 the depth of fill over the southern half of the Stage 2 area varies from 0.8m depth to 2.8m depth with constituents such as bricks, builders rubble, glass, waste metal and sand; 0 the fill is deeper in the middle and southern sections of the Stage 2 area; 0 the underlying material along the Green Belt area is very similar to that found in the southern section of "Merindah Avenue'' site with the depth of fill tapering off towards the north (near the scout hall); .. e no landfill gas was detected at the six locations tested around the site; 0 soil contamination appears to be predominantly due to heavy metals; of the thirty four samples collected, seventeen samples exhibited levels of heavy metals judged to be in excess of ANZECC B criteria (ie a level at which further investigation work is recommended), and; 0 of the groundwater samples collected from each of the three monitoring bores iristalled at the site, ozie sample exhibited an elevated salinity value, the cause of which is not apparent, but is possibly a reflection of natural conditions. 132 of 185 'These results also indicate the following: 0 The condition of the Stage 2 area is unlikely to coiistrain the issue of a Certificate of Enviroiiniental Audit for the Stage 1 area. A Certificate of Environmental Audit would not be issued for the Stage 2 area of "Merindah Avenue" unless extensive remediation measures are carried out that in any case, are unlikely to prove cost-effective, and; e In considering the issue of a Statement of Environmental Audit, the Auditor is likely to conclude that land uses consistent with the environmental condition of the Stage 2 area include continuation of the existing parkland usage or redevelopment for appropriate commercial, community or industrial use. Appropriate community uses could include: indoor and outdoor recreational and sporting facilities (eg. indoor cricket and tennis, and outdoor passive recreational areas). It is recognized that the construction of structures required for such activities would necessitate the some excavation of contaminated soil. Providing that excavated material is re-buried on the site or otherwise disposed of in accordance with EPA requirements, and that suitable occupational health and safety measures are imposed during construction, such development may be allowable within the constraints of a Statement of Environmental Audit. 5-2 133 of 185 6.0 LIMITATIONS The fiiidiiigs outlined in this report are based on data from the indicated investigation and sampling sites and based on the specific analytical program. Soil samples collected may not be representative of all conditions across the site. Inferences about the nature and the. continuity of the soil away from the soil sampling points are made, but cannot be guaranteed.
