1.0 INTRODUCTION

The Landscape & Reclamation Team of the Highways Division, Communities Department of Nottinghamshire County Council, was commissioned by Property Strategy and Development Team to undertake a geo-environmental appraisal of the Flintham Primary School with recommendations for further investigation work if deemed necessary.

1.1 Project Brief

The purpose of the geo-environmental appraisal is to collect all relevant information in order that an assessment of risk associated with future site development can be established by considering all potential contaminant sources, pathways and receptors, defined as a pollutant linkage.

The conclusions of the report then makes recommendations for any further phases of assessment where considered necessary.

The site is represented by an approximately 1.0 Ha area of land presently utilised as an educational facility.

1.2 Aims and Objectives

2.0 SITE APPRAISAL

Within the following sections information relevant to the sites location within the local landscape, potential sources of contamination and relevant receptors are assessed to enable a preliminary assessment of potential contamination risk associated with the proposed development.

2.1 Site Location

The site lies at the north-western fringe of Flintham Village, approximately 9.8km to the south-west of Newark, 18km north-east of Nottingham City Centre, at NGR 474110/346140 (Figure 1). The site occupies a road side location, with Inholms Road to the west. The school is located within a rural residential area with housing surrounding the school site to the west, south and east beyond areas of agricultural and parkland which surround the school site. A cemetery lies to the west of the site, beyond Inholms Road.

Figure 1; Site Location

2.2 Site Description

The school is located on generally level ground with a slight fall from the north-west to south-east across the site (Figure 2). The site represents a single storey, CLASP constructed Primary School facility originally built in the 1970’s, comprising classrooms, offices, kitchen and heating system/boiler room. Since its original construction the school does not appear to have been significantly added to and/or extended over its lifespan, beyond the addition of 2 No. temporary classrooms located to the north of the main school buildings.

P.Y.BE.28909.01/Flintham Primary School, Flintham -Contamination Appraisal 5

Figure 2; Existing Site Layout

Access to the Primary School is off of Inholms Road to the west, with a vehicular access road to the north-west leading to a bituminous surfaced carpark to the north of the facility and separate pedestrian access to the south-west. A further bituminous hardstanding play area lies to the south-east of the school buildings, representing a school playground. The school buildings are CLASP built, single storey and double storey, flat roofed structures representing classrooms and offices, with a kitchen, and a heating system/boiler room located to the north. The school was originally built with an oil fuelled heating system which has since been converted to electricity, with solar panels on the roof and air blowers within the classrooms. Extensive playing fields lie to the south-east of the main school buildings.

2.3 Ownership

The land is presently owned by Nottinghamshire County Council, for further information with regard to issues of ownership please contact;

2.4 Geology

Based on digital BGS mapping information, the following geological features are believed to exist;

Bedrock; Variable strata associated with the same geological formation underlie the site (Figure 3). Early Triassic, Mercia Mudstone Group; Sidmouth Mudstone Formation; Edwalton Member underlie the majority of the site to the north-west composed of Mudstone and Siltstone, red-brown and greenish grey, with beds of indurated, variably dolomitic siltstone and very fine-grained sandstone common in the lower half; finely disseminated gypsum common in upper half. The south-east of the site is underlain by subordinate Dolomitic Siltstone of the same Formation. Drift & Superficial; There are no recorded drift or superficial deposits on-site. Fault Lines; There are 5 No. identified faultlines within potential influencing distance of the site. The nearest lies approximately 175m to the north trending in a north- westerly to south-easterly orientation, with 2 No. further faults, approximately 490m

P.Y.BE.28909.01/Flintham Primary School, Flintham -Contamination Appraisal 7

and 600m to the north-east, displaying a similar orientation. 2 No. further faultlines lie to the south (orientated west to east) and south-west (orientated north-west to south- east) at distances of 475m and 690m respectively. At these distances it is deemed unlikely that the majority of these features would affect the school site; however the fault to the north could potentially extend southward towards the school site itself.

2.5 Ground & Surface Waters

• The EA Groundwater Vulnerability map indicates the site to be underlain by strata designated as Non - Aquifer rocks of negligible permeability. • The EA Bedrock Aquifer Designation is split across the site with the mudstone and siltstone deposits to the west designated as a Secondary A Aquifer and the subordinate dolomitic siltstone to the east designated as a Secondary B Aquifer. • The site does not fall within a groundwater Source Protection Zone. • The site lies within an area designated as a Nitrate Vulnerable Zone. • There are 8 No. recorded active discharge consents within 500 m of the site, related to effluent discharge to both ground and surface waters. • There are 2 No. recorded active abstraction licences within 1km of the site; associated with Newfields Farm, abstracting surface water for general farming, domestic and spray irrigation from Flintham Hall Lake (Points 1 & 2). • The nearest surface watercourse to the site is a tertiary river watercourse; lying approximately 190m to the east of the site. The nearest water feature is a small lined pond in the school grounds. • It is assumed groundwater flow is from south-west to north-east across the site, following the local topography. • The site lies within an area where flooding from surface and ground waters is deemed unlikely. • There has been 1 No, recorded pollution incident to controlled waters within 1km of the site, classified as category 3; minor incident. This incident is considered as unlikely to have adversely impacted the school site itself.

2.6 Geo-Environmental Conditions

• Collapsible Ground; Very Low Hazard • Compressible Ground; No Hazard • Ground Dissolution; No Hazard • Landslide; Very Low Hazard • Running Sand; No - Very Low Hazard • Shrinkage/Swelling of Clay; No Hazard • Radon; the area has a mixed classification, identified as both; Basic Radon protection measures are not necessary in the building of new houses or extensions and a lower probability Radon area with less than 1% of homes above the action level. It is therefore concluded that Radon protection measures are not required in any new buildings and/or extensions proposed. • Coal Mining; The site does not lie within an area which may be affected by underground and/or open cast coal mining activities.

2.7 Previous & Adjacent Development

• There are no Historic Landfill Sites within 1km of the site. • There are no Licensed Waste Management Facilities within 1km of the site. • Within the Contemporary Trade Directory there are no commercial businesses recorded within 500m of the site. • There are no BGS Recorded Mineral Sites within 1km of the site. • The only significant potential sources of off-site contamination identified within 1 km of the site include; Military Land (RAF , 741m to the north), a former sewage farm (188m to the north), a village smithy (125m to the south), a former Gasometer, without an associated gas works (250m to the south) and former covered tank (350m to the south); however although these represent potential sources of contamination, the potential for adverse on-site impact from these identified sources is considered unlikely.

2.8 Site Development Summary

The earliest OS map of 1884 indicates the site to be enclosed farmland to the north- west of Flintham Village, with no discernible adjacent development. Across the wider area the only significant developments are located to the south, including houses and small holdings within Flintham Village itself, with potentially contaminative activity limited to a local smithy, gasometer and covered tank.

Until the late-1960’s with the construction of the present school facility the site itself remains unchanged; however across the wider area changes begin to occur in the mid-1930’s with the construction of RAF Syerston to the north of the site (an operational Bomber Command base during WW2, later becoming a training facility and currently operating as a glider school).

In the 1950/60’s residential development within the village begins to gradually increase in density and extent around the site and a sewage farm is constructed to the north of the school site around this time.

Little discernible change occurs on-site from the 1960’s onward, with the notable exception of 2 No. temporary classrooms installed to the north of the facility in the 1990’s/2000’s.

2.9 Site Investigations

There are no available records of site investigations being undertaken on-site.

3.0 CONCLUSIONS & RECOMMENDATIONS

3.1 Conclusions

The site lies over strata designated as both Secondary A (west) and B Aquifers (east) of the Sidmouth Mudstone Formation; Edwalton Member. The local soils are classified as have a high leaching potential, within a Nitrate Vulnerable Area. Although the site does not lie within a Groundwater Source Protection Zone, consideration should be given for the protection of groundwater resources during any development works on-site.

There is no significant risk of surface water or groundwater flooding at the site.

There are no significant risks identified associated with ground stability, Radon gas, coal mine gas or subsidence at the site.

There are a limited number of both past and present sources of potential contamination within 500m of the site boundaries; which are considered to present potential sources of off-site ground/ground-water contamination; the sources identified include; a smithy, gasometer, sewage works and covered tank; however these identified activities are located significant distances away from the site and any adverse on-site impact would be deemed as unlikely.

On-site there are only limited potential sources of contamination. These are limited to Asbestos Containing Materials (ACM’s) within the existing building fabric & made ground surrounding the original school buildings. Potential localised, low impact, ground contamination associated with the schools original oil fuelled heating system may also be present.

A preliminary risk assessment would suggest there is a very low risk potential for both on-site and off-site contamination at this site.

3.2 Recommendations

The Flintham Primary School facility was designed and built in an era whereby a wide range of asbestos products/materials would have been installed within the building fabric.

The present redevelopment proposals include the construction of a school hall and classroom extension to the north of the present facility, connected to the existing building by a small corridor to the north-west of the facility, which may disturb the original building fabric. It is recommended a destructive asbestos survey is undertaken to examine the potential for ACM’s within the walls and other building fabric which may be disturbed.

It should also be noted that the potential exists for ACM’s within the surrounding soils associated with the schools original construction and the discard of building materials. Therefore the potential exists for ACM’s within the footprint area of the new school hall and classrooms proposed.

P.Y.BE.28909.01/Flintham Primary School, Flintham -Contamination Appraisal 10

The school was originally heated by an oil fuelled boiler system; therefore there remains the possibility of low impact ground contamination in the vicinity of the former storage tank, associated with spillage/leakage.

It is therefore recommended that a watching brief should be implemented for the groundworks phase of the proposed works to the effect that should any previously unidentified contaminant impacted materials be encountered then all works will cease and specialist technical assistance sought.

Should intrusive investigations be undertaken related to foundation deign it is recommended soil samples are obtained for limited laboratory analysis.
