Environmental monitoring report, 1980, 1981, 1982 for the former Middlesex Sampling Plant and Middlesex Municipal Landfill Sites

During periods of remedial action activities conducted in 1980 and 1981 at designated sites in the Borough of Middlesex, New Jersey, air, water, and sediments were sampled and analyzed to verify the adequacy of contamination control and compliance with applicable standards. Analytical results show that remedial action activities at the Middlesex Sampling Plant (MSP) and vicinity properties were conducted, with few exceptions, within applicable standards. During 1982, a surveillance monitoring program was initiated at the MSP and at the former Middlesex Municipal Landfill (MML) site. Radioactivity was measured in air and water to allow calculation of radiation doses to the public. The resulting dose from external gamma radiation at the MSP site boundary in 1982 was approximately twice natural background and less than 40% (background included) of the Department of Energy (DOE) standard. The highest continuous occupancy dose to the bronchial epithelium (lungs) from radon exposure at the MML boundary was approximately twice the background value or about 60% (background included) of the DOE standard. 12 references, 15 figures, 28 tables
