Dear Mr. Dellinger:
Subject: Groundwater Monitoring Results from Pump Test
The attached is a copy of the groundwater analytical results for samples taken frommonitoring wells 91, 92, 93 and 94 between May 24, 1993, and June 6, 1994. These results arealso provided in electronic format.
Surface water that is collected in the boiler house area was sampled once in 1994. Thesample was taken from the boiler house sump. Although no records of the fact were made, it isbelieved that the sample was taken between rainfall events after the surface water had beenpumped down. This data probably represents more contamination than is typically present.
The table of data also includes results of a sample taken from the "Beaver Pond" which ispart of Rocky Branch Creek, northwest of the site.
Please call if you have any questions (302-594-5951).
Sincerely,
Douglas J. KeilmanTechnical DirectorHealth & Environment
