The 2.6-acre Bioclinical Laboratories (BCL) site is located in Bohemia, Suffolk County, New York. From 1972 to 1984, BCL used the site to formulate and repackage industrial chemicals for wholesale distribution to manufacturers. During this process, indoor sinks that were used for washing chemical mixing vessels drained to the east sanitary sewer system. In 1981, a fire partially destroyed BCL's chemical inventory and resulted in surface water runoff of hazardous waste. The county ordered BCL to clean out the sanitary system and submit a plan for installing a ground water monitoring system; however, no wells were ever installed. An additional source of contamination has been partially attributed to another tenant at the site, the Panatone Finishing Corporation. Panatone utilized a leaching pool on the north side of the building to dispose of effluent. In 1985, this leaching pool was pumped out, cleaned, and removed from service. The ROD will determine the nature and extent of contamination to ensure protection of human health and the environment and is the only OU planned for the site. As a result of previous clean-up activities, risk assessment results indicate that contaminant levels do not exceed risk-based standards.
