Area of Operations: Great South Bay, New York, United States, North America, North Atlantic
Dates: June 21, 2010 to June 25, 2010
Objectives: Submarine groundwater sampling, Great South Bay, Long Island.
Type of Activity: Sampling
Information to be derived: Samples and chemical analysis
Grain size analysis
Summary: Groundwater samples were collected for dissolved metals, inorganic carbon, organic carbon, pharmaceuticals, and nutrients. Samples were collected from 14 onshore wells in Patchogue by USGS-WRD, 4 temporary offshore wells and piezometers in a shore-perpendicular transect (35 total offshore groundwater samples), 1 surface water site, and 20 temporary onshore piezometers (12 in unsewered Patchogue and 8 in sewered Babylon/Islip). Eight short sediment cores (~20-120 cm) were also collected in the Patchogue Bay area from the SCDHS barge. SCDHS personnel collected data along ~8-10 shore-perpendicular stationary electrical resistivity lines near the sediment coring sites, and collected subsurface Trident probe measurements of porewater conductivity in a transect in the vicinity of the temporary offshore wells. SCDHS personnel also collected sample splits for analysis of a variety of pollutants (e.g., pesticides, herbicides, volatile organic compounds) from low-salinity intervals in the offshore Patchogue piezometer closest to shore. The Stony Brook University student (Young) also collected sample splits for various analyses from the onshore wells sampled by USGS-WRD (Abbene).
