Sampling results, DNAPL monitoring well GW-726, Oak Ridge Y-12 plant, Oak Ridge, Tennessee. Quarterly report, April 1, 1994--September 30, 1994.

In January 1990, dense, non aqueous phase liquids (DNAPLs) were discovered at a depth of approximately 274 foot below ground surface along the southern border of the Y-12 Plant Burial Grounds. Immediately after the discovery, an investigation was conducted to assess the occurrence of DNAPL at the site and to make recommendations for further action. This report summarizes purging and sampling activities for one of these multiport wells, GW-726, and presents analytical results for GW-726
