A pile containing about 1,200 cubic yards of material is contaminated with several pesticides. Contamination of ground water, the only source of drinking water for the area, is the major concern. Possible contamination of Bells Spring, which supplies the Federal Fish Hatchery and National Fish Research Laboratory, is also of concern.
Further testing is underway to check for possible residual contamination.
The description may change as additional information is gathered on the sources and extent of contamination.
