Site Description
-
Stage of Clean-up: Construction Underway
Conditions at listing (October l98l): The Nyanza Chemical Waste Dump is adjacent to an active industrial complex in Ashland, Massachusetts. The 35-acre site is within l,000 feet of Sudbury Reservoir, which is used for recreational purposes and is considered a possible supplemental source of drinking water for the metropolitan Boston area. From l9l7 to l978, the site was occupied by numerous producers of textile dyes and intermediates. Nyanza Chemical, the last of these companies, operated from l965 to l978, when it went out of business due to financial problems. Over 45,000 tons of chemical sludges were generated by Nyanza's waste water treatment processes. Soil, ground water, and surface water are contaminated with HEAVY METALS and chlorinated organics. Mercury-laden particulates may also have been blown into the air from exposed sludges. The current owner leases the old plant to various businesses. When Nyanza sold the land, the court required that about $250,000 be placed in escrow, most of which the owner has spent on site studies. Status (July l983): In January l983, EPA signed a $500,000 Superfund State Contract with Massachusetts for a remedial investigation to determine the type and extent of contamination at the site and a feasibility study to identify alternatives for remedial action. The work is scheduled to be completed in the first quarter of l984. More...
