The Nyanza Chemical Waste Dump site is a 35-acre area next to an active industrial complex in Ashland, Massachusetts. From 1917 to 1978, facilities produced textile dyes, intermediates and other products on site. Nyanza Inc. operated on site from 1965 until 1978. Large volumes of industrial wastewater containing high levels of acids and numerous organic and inorganic chemicals, including mercury, were generated by these facilities, leading to soil and groundwater contamination. Following construction of the site’s remedy, operation and maintenance activities and monitoring are ongoing.
