Series Description: This is a single letter regarding offsite residential well water near K-25 from an unspecified author. Historical monitoring data, from testing done in 1981 and 1983 is summarized in a table accompanying the letter and compared to appropriate background contamination limits. For instance, the maximum observed concentration measured in milligrams per liter or picocuries per liter (mg/l or pCi/l), is compared against acceptable limits, which for cesium is 200 pCi/l. The letter mentions the existence of offsite wells and includes a summary of the current onsite groundwater monitoring program and plans for offsite monitoring in the future.

A similar letter regarding the Portsmouth Gaseous Diffusion Plant is attached to the back of the Oak Ridge Gaseous Diffusion Plant letter. .
