Delineation of Discharge Areas of Two Contaminant Plumes by Use of DiffusionSamplers, Johns Pond, Cape Cod, Massachusetts, 1998

摘要

Diffusion samplers were installed in the bottom of Johns Pond, Cape Code,Massachusetts, to confirm that volatile organic compounds from the Storm Drain-5 (SD-5) plume emanating from the Massachusetts Military Reservation (MMR) were discharging into the pond. An array of 134 vapor-diffusion samplers was buried by divers about 0.5 feet below the pond bottom in the presumed discharge area of the SD-5 plume and left in place for about 2 weeks to equilibrate. Two areas of high concentrations of volatile organic compounds (VOCs) were identified.
