ON 12/20/94 EPA FILED AN ADMINISTRATIVE ORDER FOR REMEDIAL DESIGN/REMEDIAL ACTION. FROM 1969 UNTIL 1986, MUNICIPAL SEWAGE SLUDGE WAS APPLIED TO APPROXIMATELY 160 ACRES ALONG THE NORTHERN AND EASTERN BOUNDARIES OF SECTION 6. THE SLUDGE WAS APPLIED TO THE SUR- FACE OF THE LAND AND THEN INCORPORATED INTO THE NATIVE SOILS. AFTER 1980, LEACHATE COLLECTED IN ON-SITE SURFACE IMPOUNDMENTS WAS INJECTED IN THE SAME 160-ACRE AREA. BOTH THE MUNICIPAL SEWAGE SLUDGE AND THE LEACHATE CONTAINED HAZ- ARDOUS SUBSTANCES.
