***Summary of Results**: Analysis of groundwater samples collected at
the Shotgun Range during CY 2001 indicates that range operations have
not impacted groundwater quality. Groundwater analyses indicate that all
metals (including lead) are at concentrations that are consistent with
established background levels.*

###### Background

The BNL shotgun range is utilized for (clay) trap and skeet target
shooting by the Brookhaven Employees Recreation Association (BERA). The
shotgun range is located in an isolated, wooded area north of the new
Waste Management Facility. The range was established by the BERA in
1974. Clay targets are thrown south from the trap house into an open
field that is approximately 205 feet east-west by 410 feet north-south
(Figure 1). Although most of the shot falls within the cleared range,
shooting from several of the trap line positions results in the
deposition of some of the shot into the nearby wooded areas.

From 1974 until 2000, the types of shotgun shells used at the facility
typically contained lead pellet. It is estimated that as many as 30,000
shotgun rounds per year have been used at the range. At an average of
1.125 oz. per round, as much as 2,100 pounds of lead may have been
deposited on the surface of the range annually. To prevent additional
deposition of lead, in early 2000 BNL implemented a rule that allows
only steel shot to be used at the range.

###### Environmental Monitoring Program

In accordance with DOE Order 5400.1 (Environmental Protection), BNL
established a groundwater monitoring program at Shotgun Range to
evaluate potential impacts of range operations on environmental quality.
In January 2000, BNL installed two wells (046-02 and 046-03) to improve
its ability to monitor groundwater quality directly downgradient of the
range. The groundwater monitoring program for the Shotgun Range is
described in the BNL Environmental Monitoring Plan (Daum *et al*. 2000;
BNL, 2001).

###### Monitoring Results

During CY 2001, groundwater monitoring wells at the Shotgun Range were
sampled in March. All metals concentrations were below the applicable
New York State Ambient Water Quality Standards (NYS AWQS) and were
consistent with established background levels (Table 1).

**Future Monitoring Actions**

The following actions are recommended:

-   Continue with collecting groundwater samples on an annual basis for
    CY 2002, and test only for metals.

-   Consider reducing the groundwater monitoring program from an annual
    schedule to once every two years starting in CY 2003.
