Water-Quality Data and Methods of Analysis for Samples Collected Near a Plume ofSewage-Contaminated Ground Water, Ashumet Valley, Cape Cod, Massachusetts, 1993-94

摘要

Water-quality data were collected and analyzed by the U.S. Geological Survey andABB Environmental Services, Inc., in 1993-94 to characterize the nature and extent of a sewage-contaminated ground-water plume underlying the Ashumet Valley in northeastern Falmouth on Cape Cod, Massachusetts. The source of the plume was the disposal of wastewater and chemicals at the Massachusetts Military Reservation's (MMR) sewage-treatment plant and former fire-training area. Water samples were collected from 315 observation wells, 31 multilevel samplers, 14 screended-auger brings, and the sewage-treatment-plant effluent to describe the plume, provide information for use in developing remedial alternatives, and improve the understanding of the fate and transport of ground-water contaminants. The data include analyses of physical properties, major ions, nutrients, metals, dissolved gases, organic compounds, other sewage-plume constituents, such as methylene blue active substances and boron, and microbiological data, such as bacterial size and abundance.
