Ground-Water Quality Near a Scavenger-Waste Disposal Facility in Manorville, Suffolk County, New York, 1984-85

摘要

Sludge from sewage-treatment plants and septic tanks was discharged to unlined infiltration basins at a scavenger-waste-disposal facility in Manorville, in South-central Suffolk County, during 1964-82, and solid waste was accepted during 1960-72. Three test borings were made at the site and ground-water samples collected in 1984 and 1985 to examine the effects of the waste on local ground-water quality in the upper glacial aquifer. The report describes the local hydrogeology and water quality of the upper glacial aquifer within the 0.88-sq mi (square mile) area around the facility and, briefly, that of the upper part of the Magothy aquifer at the site. Data are presented in tables of the chemical quality of the ground-water samples collected in August 1984 and June 1985, and in maps, cross sections, and diagrams showing concentrations of selected chemical constituents in the upper glacial aquifer in June 1985.
