1.0 INTRODUCTION

Shaw Environmental, Inc. (Shaw) has developed this Technical Memorandum, on behalf of the United States Army Corps of Engineers (USACE), to summarize environmental conditions on a section of the Patroon Creek (Creek) located in Colonie and Albany, Ndw York. The Creek generally flows west to east for approximately six miles from the area of 6-mile Reservoir through 3-Mile Reservoir to the Hudson River (Figure 1, Site Location Map). Past studies of the Creek and 3-Mile Reservoir suggests that the former National Lead Industries (NL) Site may have discharged Uranium, Thorium and Lead to the Creek via an unnamed tributary to the Creek that transects the NL site. In addition to former operations at NL, other historic manufacturing activities are known to have had an adverse impact on the Creek.

USACE is currently completing environmental remediation activities at the NL site and preparing to develop a Sediment Sampling Work Plan to further investigate sediment conditions in the area of the unnamed tributary and 3-Mile Reservoir. This Technical Memorandum is intended to provide a better understanding of the environmental conditions in the Creek between 6-mile Reservoir and 3-Mile Reservoir including the unnamed tributary and the lower portion of the North Branch (Figure 1). This information will be provided to support the development of the Sediment Sampling Work Plan. This memorandum includes:

• A description of the Creek,

• A summary of the historical use of the Creek,

• A summary of sediment and water quality data within the Creek as available, • A summary of sites known to have discharged to the Creek within the bounds of this study,

• An overview of construction activities that have occurred to the Creek and 3-Mile Reservoir.

To support the development of this memorandum and to gain an understanding of the historic investigations performed at the Creek and an understanding of the Creek itself, the following interested parties were contacted and interviewed in person or by phone.

• USEPA (Region 2)-Tom Taccone regarding Mercury Refining project status • NYSDEC (Central Office) - Paul Patel regarding Patroon Creek Investigations • NYSDEC (Central Office) - Ron Sloane regarding Patroon Creek Investigations

2.0 SITE DESCRIPTION

The Patroon Creek Watershed includes approximately 33 square kilometers and is drained by Patroon Creek and its tributaries. The Creek generally flows from west to east in the towns of Colonie and Guilderland and eventually empties into the Hudson River in the City of Albany (Figure 1). The flow within the Creek ranges from approximately 350 cubic feet per second (cfs) to 600 cfs. The area surrounding Patroon Creek is a mixture of residential, commercial and light industrial properties. Patroon Creek is designated as a Class C Water Body (suitable for primary / secondary contact recreation and suitable for fish propagation and survival) in the New York State Section 303(d) List of Impaired Waters.

In the mid to late nineteenth century, four (4) surface reservoirs were constructed by the City of Albany Water Department along the Creek for water supply purposes. The Creek originates at the western most of these reservoirs known as Rensselaer Lake. This reservoir will be referred to within this document as 6-Mile Reservoir. Approximately half way along the length of the Creek, the Creek passes through Patroon Reservoir, also known as Russell Road Reservoir, and 1-90 pond. This reservoir will be referred to within this document as 3-Mile Reservoir. Near its eastern end, the Creek, formerly flowed through a third reservoir known as Tivoli Lake prior to reaching the Hudson River. According to the City of Albany Department of Water, a fourth reservoir, Sand Creek Reservoir was formerly located along the Creek, however, information regarding the exact location of Sand Creek Reservoir was not identified.

Between 6-Mile Reservoir and 3-Mile Reservoir there are two tributaries to the Creek. The western most of these tributaries is known as the North Branch of the Patroon Creek. The second tributary is unnamed and will be referred to as the unnamed tributary for the purpose of this report. This unnamed tributary formerly flowed through the former Patroon Lake located on the NL site. The focus of this report will be the area between 6-Mile Reservoir and 3-Mile Reservoir including the unnamed tributary and the North Branch. This area of the Creek will be referred to as the Site (Figure 1).

3.0 SITE HISTORY

Patroon Creek originates in the Pine Bush Natural Area northwest of Albany, New York. In the 17th Century the Creek served as a source of power for a number of gist and saw mills and it became a major source of water for the growing Albany population. In'the early eighteen hundreds, the privately owned Water Works Company created Tivoli Lakes using a portion of the watershed area of Patroon Creek as part of their water supply system for the City of Albany.

In 1850 the Albany Board of Water Commissioners was formed and purchased Albany's water supply from the Water Works Company. Under the management of the Albany Board of Water Commissioners, 6-Mile Reservoir was created to help supply water to the growing Albany population by damming three streams at the Patroon Creek headwaters. In the late Nineteenth Century the Patroon Creek water supply consisted of 6-Mile Reservoir, Sand Creek Reservoir, 3-Mile Reservoir and the Tivoli Lake Reservoir. This system of reservoirs would remain a source of water for the City of Albany until the early 1920's. Due to contaminant issues associated with the proximity of the railroad and sanitary and stormwater runoff, the City of Albany discontinued the use of the reservoir systems in the early 1920's and began to utilize other water supply sources.

4.0 POTENTIAL CONTAMINANT SOURCES TO PATROON CREEK

To determine what environmentally active sites were located within a one (1) mile radius of the NL Site, Shaw contracted Environmental Data Resources, Inc. (EDR). EDR is a commercial business that publishes reports summarizing available environmental records in accordance with the requirements of ASTM Standard Practice for Environmental Site Assessments, ASTM

E-1527-00.

Shaw obtained and reviewed the EDR report (available for review) for the property located at 1130 Central Avenue (NL Site) which provided an extensive compilation of listed sites within a 1-mile radius of the target property. Shaw reviewed the EDR report for hazardous sites that may have had a substantial impact to the sediments within the Patroon Creek. The two primary sites identified included the Mercury Refining Site and the former NL Site described below.

M:/194reps/Patroon Creek/Patroon Creek_063003 United States Anny Corp. of Engineers 6 Technical Memorandum - Patroon Creek Watershed June 30,2003

5.0 HISTORIC SITE INVESTIGATIONS

In the early 1980's, due to ongoing environmental concerns, the New York State Department of Environmental Conservation (NYSDEC) designated the Patroon Creek as a Class C Water Body in the New York Sate Section 303 (d) List of Impaired Waters. Portions of the Patroon Creek watershed have also have also been designated as Areas of Concern by the NYSDEC.

Upon review of environmental databases, conversations with the NYSDEC and United States Environmental Protection Agency (USEPA), and review of relevant documents, four sediment investigations were identified for the Creek area of concern. These include:

• USDOE/USACE investigations of NL

• USEPA investigation of Mercury Refining • State University of New York (SUNY) at Albany investigation of Patroon Creek under USEPA EMPACT Grant

• NYSDEC - Patroon Creek

The Mercury Refining is a USEPA Superfund site located on the Patroon Creek between 6-Mile Reservoir and 3-Mile Reservoir. Mercury Refining is located off of Railroad Avenue and on the North Branch of the Patroon Creek. The former NL Site is a NYSDEC Superfund site and is located off of Central Avenue on the unnamed tributary. < Both sites have completed studies of a portion of Patroon Creek including sediment sampling and analyses.

In the late 1980's, the NYSDEC performed an in-depth study of fish populations, surface water quality and sediment quality within the Creek. Between 1999 and 2002, Dr. John G. Arnason at the State University of New York (SUNY) at Albany collected a sediment core from within 3-Mile Reservoir to evaluate the deposition of cadmium, mercury, lead, and uranium in the reservoir's sediments.

Additional industrial sites (including General Electric Vetrano Road and Tobins First Prize) are located in the vicinity of Patroon Creek, however, as of the date of this Technical Memorandum, information relative to these sites and their potential contaminant impacts has not been obtained. A detailed discussion of the Mercury Refining Site and NL Site and the investigative work performed on Patroon Creek is provided below.

M:/194reps/Patroon Creek/Patroon Creek_063003 United States Amly Corp. of Engineers 7 Technical Memorandum - Patroon Creek Watershed June 30,2003

5.1 National Lead Industries

The NL Site is a former industrial manufacturing site located at 1130 Central Avenue in the Town of Colonie, New York. The site is currently under environmental restoration activities by the USACE and consists of 11.2 acres and 56 vicinity properties.

Manufacturing operation at the site began in 1923, with the Embossing Company, which manufactured wood products and toys. In 1927 Magnus Metal Company purchased the property and began operating a brass foundry for manufacturing railroad parts.

In 1937, NL purchased the facility and an adjacent parcel that contained a portion of Patroon Lake. NL continued the operation of the brass foundry and began filling Patroon Lake sometime prior to 1941. After World War Il, NL began casting aluminum mainframes for airplanes and by 1958 the nuclear division was producing items from uranium and thorium under a license from the Atomic Energy Commission. Operation of the brass foundry was discontinued in 1960.

From circa 1958 to 1984, NL used radioactive materials consisting mainly of depleted uranium (DU) and smaller amounts of thorium and enriched uranium. A building on the site was used for electroplating and manufacturing various components and reportedly properties in the vicinity of the NL Site were contaminated through plant smokestack releases into the air. Contaminated casting sand and debris were disposed of in the former Patroon Lake area on the NL Site and radioactive and chemical contaminants (mainly uranium, thorium and lead) entered the environment resulting in soil, sediment and groundwater impacts. Based on NL Site conditions the New York State Supreme Court shut down the National Lead plant in 1984.

From 1984 to fall of 1997, the NL Site was managed by the U.S. Department of Energy (DOE). During this time, DOE completed site investigation activities, remedial activities at 53 vicinity properties, and demolished all the former NL buildings. An Engineering Evaluation/Cost Analysis, finalized in 1995, outlines the site remedy selected by DOE. In 1997, the USACE assumed control of the site and the responsibility for the remaining assessment and remedial activities. USACE is currently remediating the former NL site and 3 remaining vicinity properties (Niagara Mohawk substation, Town of Colonie property, and CSX rail property) that contain residual radioactive and chemical constituents above Federal and State guidelines.

Sediment sampling near the NL Site was performed within the unnamed tributary, the Creek between the Northern Branch and 3-Mile Reservoir, and within 3-Mile Reservoir. Between the years of 1984 and 2001, sediment samples were typically collected at the NL Site sampling

M./194 reps/Patroon Creek/Patroon Creek_083003 United States Army Corp. of Engineers 8 Technical Memorandum - Patroon Creek Watershed June 30,2003 location (where the unnamed tributary runs through the NL Site) and at up to three additional sample locations downstream of the NL Site on the unnamed tributary. In 1992, the sediment sampling program was modified to include; one background sample on the unnamed tributary upstream of the NL Site, one sample on the unnamed tributary downstream of the NL Site, one background sample at the confluence of the Northern Branch and Patroon Creek, and four sediment samples between the unnamed tributary and the 3-Mile Reservoir dam. The DOE and USACE sediment samples were collected at various depths ranging from surface grab samples to approximately 4.5 feet below the bottom of the Creek.

All sediment samples were analyzed for radiological contaminants of concern. In addition in 1992, 1999, and 2001 metals were included in the analyses. The 2001 sediment investigation also included total organic carbon, volatiles and semivolatiles in the sediment analyses.

For the purpose of this report, sediment sample results were compared to the 35 pCi/g criteria for Uranium in soils and 5 pei/g for Radium and Thorium. The results of the DOE/USACE sediment sampling from 1984 through 1998 (Appendix B) were relatively consistent. The upstream (background) locations had levels in the range of 0.68-6.5 pCi/g for total Uranium. The on site locations in the Patroon Lake area had the most elevated levels, with levels of 278 pCi/g in 1989 and158.4 pCi/g in 1990. The downstream locations all had levels below 35 pCi/g except for a sample taken in 1992 which had a total Uranium level of 128.3 pCi/g at a depth of 1.5-2.5 feet.

The results from the 2001 Sediment Sampling Report (6 upstream locations, 6 downstream locations) show an upstream range of.261 - .841 pCi/g and a downstream range of.195 -7.06 pCi/g. The results indicate all samples are well below the 35 pCi/g criteria.

5.2 Mercury Refining Inc.

Mercury Refining, Inc. is a former battery reclamation facility located at 26 Railroad Avenue in the Town of Colonie, New York. The half-acre site is located near the Northern Branch of Patroon Creek in a light industrial and commercial area. Mercury reclamation operations were performed at the Mercury Refining site from 1956 to 1998 and the property is currently used as a transfer facility for waste material which is shipped off-site for mercury reclamation.

Based on the USEPA's Site Fact Sheet (EPA, April 2002), operators at the Mercur·y Refining site historically dumped waste batteries behind an on-site furnace building until 1980. These

M:/194reps/Patroon CreeuPatroon Creek_063003 United States Anny Corp. of Engineers 9 Technical Memorandum - Patroon Creek Watershed June 30,2003 operations resulted in soil, groundwater, and sediment contamination. The Mercury Refining site has been under active investigation and remediation since the early 1980's and the primary constituents of concern are: mercury, lead, and PCBs in the soil; cadmium, mercury, and lead in groundwater; and mercury, lead, and PCBs in the sediments of the Northern Branch of Patroon

Creek and Patroon Creek itself.

In 1983 Mercury Refining was placed on the National Priority List (NPL) and in 1985 the NYSDEC issued the first Consent Order to Mercury Refining to conduct remedial activities at the site. Under this order, 2,100 cubic yards of mercury laden soil and debris and 300 cubic yards of PCB contaminated soil were excavated and disposed of off-site. During the remedial activities, additional contamination was found beneath the furnace building. This material was sealed in plastic sheeting and left in place. The property was then re-graded and capped to prevent rainwater infiltration. In 1989, the NYSDEC issued a second Consent Order, requiring Mercury Refining to curtail any further chemical releases to the environment. In early 1993, the NYSDEC issued Mercury Refining a third Consent Order requiring Mercury Refining to clean-up the remaining on-site contamination, provide long-term monitoring of on-site soil and groundwater, and assess off-site soil conditions and sediment conditions within Patroon Creek,

In 1996, the NYSDEC issued a Hazardous Waste Corrective Action permit requiring the control, generation and storage of hazardous waste on-site. The Permit also required Mercury Refining to remediate, remove and continue to monitor on-site soil and groundwater impacts and off-site soil impacts and sediment quality within of Patroon Creek.

In November 1999, the NYSDEC requested that the USEPA assume the role as the managing regulatory agency due to Mercury Refining's non-compliance with the Orders and Permit. Since 1999 the USEPA has been conducting a Remedial Investigation/Feasibility Study (Rl/FS) at the Mercury Refining Site and Patroon Creek. To date no documents have been released to the public. The expected date of completion of the Rl/FS is July 2003.

Shaw has been in communication with the USEPA project manager and has obtained the USEPA's data for Patroon Creek sediment sampling. This information is presented on Figure 2, Historic Sediment Locations and Data and the data tables are included in Appendix C, Mercury Refining USEPA Data. The data indicates that twelve locations were sampled along the North Branch and Patroon Creek to just below the spillway of 3-Mile Reservoir. Background samples were also collected upstream on the North Branch at Inga's Pond and upstream of the

confluence of the North Branch and Patroon Creek near 6-Mile Reservoir.

M:/194reps/Patroon Creek/Patroon Creek_063003 United States Anny Corp. of Engineers 10 Technical Memorandum - Patroon Creek Watershed June 30,2003

Surface water and sediment samples were collected at all sampling locations. At five locations fish samples were also collected. Review of the data indicates that slightly elevated concentrations of mercury and lead are present in the sediments of the North Branch, within the sediments of the Patroon Creek (downstream of the confluence of the North Branch and Patroon Creek) and within 3-Mile Reservoir. Elevated concentrations of PCBs were also detected in the sediments of 3-Mile Reservoir just before the dam. Radiological sampling was not performed. The EPA has not released any preliminary clean-up goals (PRGs) to date.

During an interview with the NYSDEC on June 20,2003, the NYSDEC indicated that 3-Mile Reservoir is likely to be dredged by the USEPA to remove PCB sediment contamination. The potential dredging of the Creek and 3-Mile Reservoir has not been confirmed by the USEPA. Allegedly, the USEPA is to release the Preliminary Remedial Action Plan for the Mercury Refining Site in Late July/Early August 2003.

5.3 State University of New York at Albany

In 2002, the USEPA awarded an EMPACT grant to the Patroon Creek Monitoring, Management and Restoration Program (PCMMRP) to establish Patroon Creek as a living classroom to promote awareness and stewardship and to provide the public with time relevant data about the Patroon Creek Watershed. In addition, the grant was to establish an environmental and public health network that paid special attention to urban neighborhood concerns. The PCMMRP, lead by Robert F. Cross, Commissioner, City of Albany, Department of Water, is a consortium of interested parties including: the City of Albany, the Arbor Hill Environmental Justice Corporation, the W. Haywood Burns Environmental Education Center, University at Albany, Albany Pine Bush Preserve Commission, Albany County Department of Health, NYSDEC, United States Geological Survey (USGS), Rennselaer Polytechnic Institute, Essential School at Albany High School, Hudson Basin River Watch, and Clearwater Chapter of Trout Unlimited. In addition to the USEPA EMPACT Grant, the PCMMRP received funding from the NYSDEC in 2002 to establish two monitoring stations along Patroon Creek.

Under this program, Dr. John G. Arnason of SUNY at Albany conducted a depositional study of cadmium, mercury, lead, and uranium in the sediments of 3-Mile Reservoir. In 1999, Dr. Arnason collected a 3 meter long sediment core from the downstream end of 3-Mile Reservoir in approximately 2.5 m of water. Reportedly, this sampling location was chosen because coring could be advanced to a greater depth, and the sediments were less likely to be disturbed. Dr. Arnason collected bulk sediment samples from the core at 0.05 meter intervals and analyzed

M./194reps/Patroon Creek/Patroon Creek_063003 United States Army Corp. of Engineers 11 Technical Memorandum - Patroon Creek Watershed June 30,2003 the samples for total cadmium, lead, mercury and uranium. The report of this analysis is presented in Appendix D.

Dr. Arnason's study indicates that total mercury concentrations range from approximately 1 mg/kg to 6.2 mg/kg at depths of creek bottom to 1.7 meters below creek bottom. At depths greater than 1.7 meters concentrations of total mercury ranged from less than 1 mg/kg to 1 mg/kg. The most elevated concentrations of total mercury (6.2 mg/kg and 4.1 mg/kg), were found at 0.8 meters and 0.64 meters. Dr. Arnason found that total cadmium, lead and uranium displayed similar patterns, with the deepest portion of the core having the lower concentrations and the mid-section of the core (0.75 meters to 1.5 meters below creek bottom) having the most elevated concentrations. Total Uranium concentrations ranged from 1 mg/kg to 320 mg/kg.

Based on correlation of historical industrial activities with the concentration profiles, Dr Arnason concludes that estimated minimum average sedimentation rate in 3-Mile Reservoir from 1955 to 1999 is approximately 0.04 meters per year with a minimum depositional rate of approximately 28 kg per square meter per year. Dr, Amason correlated the data and depositional depth with the previous industrial practices along Patroon Creek. Dr. Arnason suggests that the concentration profiles of cadmium, mercury, lead, and uranium represent industrial pollution related to the Mercury Refining and National Lead sites from the mid-1950's to the present day.

After Dr. Arnason had finished his field work for this study, NYSDEC requested to share samples with Dr. Arnason for verification purposes. Dr. Arnason honored this request and supplied split samples to the NYSDEC. In a letter to Dr. Amason, dated Feb. 2003, the NYSDEC provided Dr. Arnason with their analytical results for isotopic uranium, which confirmed the presence of depleted uranium. The results are presented in Appendix D. The NYSDEC results confirm the presence of depleted uranium above 35 pCi/g criteria in one interval of the sediment sample collected by SUNY (U-238 at 167 cm bgs).

In addition to Mr. Arnason's investigation, the USGS and Dr. George Robinson at SUNY of Albany are currently collecting additional information about Patroon Creek under the PCMMRP. The USGS provides real-time stream gauging data and water quality information to the public under the W. Haywood Burns Environmental Justice Corporation Website. Dr. Robinson is currently completing his study of the Riparian Zone and Wetlands of Patroon Creek and is anticipating completing his study in late 2003.

5.4 New York State Department of Environmental Conservation

In the late 1980's, the NYSDEC performed an in-depth study of fish populations, surface water quality and sediment quality within the Creek. Allegedly the results of this investigation led to the designation of the Creek as a Class C Water Body in the New York State Section 303 (d) List of Impaired Waters. The specific information and data collected dGring the NYSDEC study has not been received as of the date of this submittal. If available from the NYSDEC, this 1980's data/information will be utilized during the development of the Sediment Sampling Work

Plan.

6.0 CHANGES TO PATROON CREEK AND ITS RESERVOIRS

In preparation for the development of this memorandum, Shaw performed a site walk of the Creek between the unnamed tributary and 3-Mile Reservoir. During the site walk it was noted that the railroad parallels the entire length of the Creek and that constrOction of the Interstate 1- 90 had likely altered the streambed of the Creek and 3-Mile Reservoir. To further investigate construction changes to the Creek, an aerial photograph search was performed and the City of Albany Water Department and the New York State Department of Transportation were interviewed. Based on the NYSDOT 1-90 construction drawings, in many locations, the Creek has been straightened into an engineered channel and diverted through culverts under the interstate.

Aerial photographs were obtained for the area of 3-Mile Reservoir for the years of 1942, 1968 and 1974 and are included in Appendix E. Review of the earliest of these photos indicates that 3-Mile Reservoir was originally composed of two basins, one to the west and a second to the east that were separated by a dividing dam and spillway. It is apparent when comparing the 1942 and 1968 photographs that Interstate 90 (I-90) had been built across 3-Mile Reservoir, destroying the western basin and significantly reducing the size of the eastern basin.

On June 11, 2003, interviews were held with the City of Albany Water Department to gain an understanding of the historic use of 3-Mile Reservoir and how it may have been altered by the construction of 1-90 and other storm water management projects. The Water Department confirmed that Patroon Creek and 3-Mile Reservoir was used for water supply purposes in the late 1800's and the western basin was designed to act as a sedimentation basin to reduce sedimentation rates in the eastern basin where water was collected for use. The Water Department indicated that they were not sure whether or not the construction of Interstate 90 included the dredging of 3-Mile Reservoir. The New York State Department of Transportation (DOT) was also contacted and interviewed concerning the construction of 1-90. Through DOT records, Construction Drawings for 1-90 along Patroon Creek were obtained. Based on the review of these drawings (Appendix F) it was confirmed that the dam and gate of the western basin was removed, and 1-90 was constructed over approximately 75% of the western basin and approximately 50% of the eastern basin.

Based on standard engineering practice, it is likely that the sediments of 3-Mile Reservoir were dredged and disposed of prior to and during the construction of 1-90. Shaw has been unable to

M./194reps/Patroon CreeldPatroon Creek_063003 United States Amly Corp. of Engineers 14

Technical Memorandum - Patroon Creek Watershed June 30,2003 determine the volume of sediments removed and their disposal location. Investigation into this matter is ongoing, and the results will be included in the Sediment Sampling Work Plan.

7.0 SUMMARY

• The Patroon Creek flows approximately six miles in a easterly direction from 6-Mile Reservoir to the Hudson River. The Creek and the associated reservoir system was formerly utilized by the City of Albany as a drinking water supply and its use as a water supply was reportedly discontinued due to contaminant issues associated with the proximity of the railroad and sanitary and storm water runoff. The City of Albany currently receives its water supply from Alcove Reservoir located southwest of Albany and no known uses of the Creek as a drinking water supply were identified. Recreational use of the Creek and 3-Mile Reservoir is unrestricted.

• As a result of industrial and commercial development along the Creek, Creek sediments are impacted with PCBs, metals, semi-volatiles, and radiological contaminants. Concentrations of each of these contaminants are above NYSDEC Technical Guidance for Screening Contaminated Sediments, January 25, 1999. The two most significant industrial practices known to have impacted the Creek, NL and Mercury Refining: ceased operations in approximately 1984 and 1999, respectively. • Review of aerial photographs and DOT drawings for Patroon Creek and 3-Mile Reservoir reveal that the flow path of the Creek and the dimensions of the reservoir have been substantially altered by the construction of I-90 in the early1960's. Based on standard engineering practice, it is likely that the sediments of 3-Mile Reservoir were dredged and disposed of prior to and during the construction of 1-90.

~~"Capsule"·. Upstream, sedinient Cd, Hg, Pb and U concentrations in Pafroon Reservoir are significantly above levels detrimenial to aqualic organisms.~~

~~Abstract~~

Sediments of the Patroon Creek watershed (33 km2) are known to contain significant concentrations of heavy metals derived from two industrial sites within the watershed. Mercury Refining, Inc (Mereco) has stored and recycled Hgfrom !955 to the present 4 .------/ day, and National Lead Industries (NLI) manufactured aircraft components containing Cd, Pb, and U from 1958 to 1984. Here we present the first record of heavy metal deposition as preserved in a 3-m long sediment core collected in 1999 from Palroon Reser- voir, a small water body (1.3 ha) downstream of the industrial Sites. Bulk sediment samples were collected from the core at 0,05-m intervals and analyzed for total Cd. Pb, and U by ICP-MS and total Hg by CVAAS. Total Hg increases from less than 1 mg kg-' (dw) below 1.68 m, to a maximum of 6.2 nig kg-' at 0.80 m, and then declines to the sediment-water interface. Total Cd, Pb, and U concentrations increase abruptly above 1.68 m to maximum values of 25, 320, and 3600 mg kg-' (dw), respectively, and then decline gradually upwards. By correlating metal profiles with industrial history, we conclude that the 1.68 m horizon was deposited no earlier than 1958, the beginning of aircraft component manufacturing at NLI. The average, apparent sedimentation rate within the reservoir has a minimum value of -0.04 m year- 1 for the 41-year period from 1958 to ! 999. In the interval 0- 1.68 m, average concentrations of Cd, Hg, Pb, and U are 1.69,1.50,461, and 13 nig kg-', respectively. These levels are comparable with other lake, reservoir and stream sediments that have been moderately to severely impacted by industrial pollution and are above levels expected - to be detrimental to aquatic organisms. © 2003 Elsevier Science Ltd.

Several recent studies have documented heavy to the sediment-water interface through diffusion (e.g. metal deposition in lake and reservoir sediments (e.g. Van Den Berg el al., 1999), sediment re-suspension (e.g. Kihkanen et al., 1998; von Gunten et al., 1997; Lorey ten Hulscher et al., 1992), or biological activity such as and Driscoll, 1999).
