Approved By:
Independent Measurements and p Environmental Protection Section Inspection Summary Inspection on February 9, 1982 (Report No. 2739/82-01(DEPOS))
Areas Inspected:
Nonroutine announced sample collection of offsite United States Geological Survey (USGS) monitoring wells east of the former licensee's property, in response to elevated tritium concentrations from two Wells reported by USGS. The inspection involved three inspector-hours onsite by one NRC inspector.
Results: No items of noncompliance wer9 identified. Final results will be appended to this report when available.

DETAILS 1.
Persons Contacted
- Russel Moore, Site Manager Andy Armbrust, Health Physicist Gary Mackey, Geologist, USGS
- Discussed scope and purpose of sample collection on February 9, 1982.
2.
Scope Samples were collected from eight offsite USGS monitoring wells east of the former licensee's site boundary. This sample collection was prompted by a USGS report of relatively elevated 'M levels from two monitoring wells numbers 563 and 575, of 90 and 60 nanocuries per liter respectively, during routine sample analysis. These levels are below the 3,000 nanocuries per liter (3E-3 microcuries per milliliter) con-centration limit for unrestricted areas defined in 10 CFR 20.106(a),
Appendix B, Table II.
U.S. Ecology representatives took independent comparable samples from these two wells concurrent with the inspector.
In addition, two snow samples were collected at an approximate 5-6 foot radius of wells 5',3 and 575 sample casings.
The offsite wells were drilled by the USGS during November and December of 1981.
Figure 1 shows the location of all wells installed and those sampled.
3.
Sample Collection and Analyses Approximately one quart samples were collected from the water level of eight offsite wells; water levels and depths of each corresponding well, as furnished by the USGS, are given in Table 1.
Wells 563 and 575 each had an individual sample bailer to minimize cross contamination; only a communal baller was available for the other wells sampled.
All samples were forwarded to Argonne National Laboratory (ANL) for tritium analysis; samples from wells 563 and 575 were also sent to the DOE Radiological Environmental Services Laboratory (RESL) in Idaho Falls, Idaho for gross alpha, gross beta, 'H,
Sr,
Sr, and gamma isotopic analyses.
The ANL results (Table 2) for wells 563 and 575 essentially confirmed the USGS results. Tritium results for the other wells and the two snow samples were within the normal range for ground water. The RESL analyses results will be appended to this report when they become available.

Exit Interview The scope and purpose of the sample collection was discussed with the site manager on February 9, 1982.
