The Yaworski Waste Lagoon site is located in Canterbury Township, Connecticut. The area is a dewatered and backfilled lagoon, about 800 feet by 300 feet and 12 feet deep. From about 1948 to 1973, drummed material and bulk wastes, including textile dyes, solvents, resins, acids, caustics, still-bottom sludges and solvent-soaked rags, were disposed of in the lagoon. Periodically, flammable liquid waste was burned in several pits in the lagoon area until 1965, when the Connecticut Department of Health ordered a halt to on-site burning of waste. The combined efforts of local residents and state and local officials concerned about adverse human health and environmental effects from disposal operations at the site led to the end of all dumping at the site in 1973. Following cleanup, operation and maintenance activities and monitoring are ongoing.
