State of the Aquifer, Long Island, New York Background In recent years, more and more people have become concerned about Long Island's supply of freshwater. Currently, there is no comprehensive, island-wide resource that summarizes recent U.S. Geological Survey (USGS) research related to the Island's aquifer system. A webpage will be developed by the USGS that will compile published data from the hydrologic-surveillance program, in place since the mid-1970’s, and various USGS sources, and supplement this information with more recent seasonal and annual hydrologic technical assistance will be provided to the Suffolk County Water Authority (SCWA) to help them produce an easy to understand annual report that will provide a snapshot of the state of Long Island's...

However, the occurrence and spatial distribution of PFAS throughout the surficial aquifer is not well established. Shallow groundwater samples were collected in 2018 from two observation well networks; the Sentinel network and Wastewater Treatment Plant groundwater (WTPGW) network. The Sentinel network is an island-wide group of wells screened within the shallow upper glacial (surficial, <100 feet deep) aquifer, which were sampled to assess the occurrence of PFAS in different land-use settings. The WTPGW network...

Concern about local details in the hydrogeologic framework that may not be represented in HA-709 has led the USGS, in cooperation with the U.S. Environmental Protection Agency (EPA), to assess the hydrogeology of the Long Island area so ground-water-flow modeling planned by EPA can more fully reflect local hydrogeologic conditions. Objectives - The primary objective of this project is to construct geographic information system (GIS) datasets of the altitudes of the...

The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic noise. In areas that have a strong acoustic contrast between the bedrock and overlying sediments, the seismic noise induces resonance at frequencies...
