    Aueust 8, 1996

    Mr. Phillip B. Dellinger U.S.EPA Region VI Suite 1200 (6WQ-SG) 1445 RossAve Dallas TX 75202-2733

    Dear Mr. Dellinger:

    Subject: Groundwater Monitoring Results from Pump Test

    The attached is a copy of the groundwater analytical results for samples taken from monitoring wells 91, 92, 93 and 94 between May 24, 1993, and June 6, 1994. These results are also provided in electronic format.

    Surface water that is collected in the boiler house area was sampled once in 1994. The sample was taken from the boiler house sump. Although no records of the fact were made, it is believed that the sample was taken between rainfall events after the surface water had been pumped 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 is part of Rocky Branch Creek, northwest of the site.

    Please call if you have any questions (302-594-5951).

    Sincerely,

    Douglas J. Keilman Technical Director Health & Environment
