From May 2017 to November 2019, the U.S. Geological Survey conducted bathymetry surveys of New York City's East of Hudson Reservoirs. The East of Hudson Reservoirs consist of 16 reservoirs and controlled lakes in Putnam and Westchester County, New York, including Amawalk Reservoir, Bog Brook Reservoir, Boyd Corners Reservoir, Cross River Reservoir, Croton Falls Reservoir, Diverting Reservoir, East Branch Reservoir, Kensico Reservoir, Kirk Lake, Lake Gilead, Lake Gleneida, Middle Branch Reservoir, Muscoot Reservoir, New Croton Reservoir, Titicus Reservoir, and West Branch Reservoir. The East of Hudson Reservoirs form New York City's Croton Water Supply System, and also include parts of the Catskill/Delaware Water...

Concentrations of 1,4-Dioxane, Per- and Polyfluorinated Substances (PFAS), Chlorofluorocarbons (CFCs), Methyl Tert-Butyl Ether (MTBE), and Trihalomethanes (THMs) in Groundwater, Nassau County, New York, 2019-2022

This data release contains 1-4 dioxane, per- and polyfluoroalkyl substances (PFAS), chlorofluorocarbons (CFCs), methyl tert-butyl ether (MTBE), and trihalomethanes (THMs) concentration data from groundwater samples collected from 78 monitoring wells in Nassau County New York. Samples were collected from May 2019 through December 2022 at wells ranging in depth from twenty-three feet to 875 feet. All wells were sampled with a submersible pump and a subset of five wells were sampled using a dual membrane passive diffusion sampler for method comparison. Water-quality field parameters (water temperature, pH, turbidity, specific conductance, and dissolved oxygen) were measured during each site visit and are included....
