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 aquifer system.
The State of the Aquifer (SOTA) webpage may include the following content:
1. Hydrogeologic framework, hydrologic cycle, and general groundwater-flow information.
2. Population and landuse showing the extent of urbanization through maps and figures using current landuse/landcover and census data.
3. Precipitation and recharge analyzing annual precipitation and departure from long-term means represented as figures and tables and describing aquifer-recharge zones.
4. Groundwater withdrawals showing density of supply wells, estimates of withdrawals, location of sewer districts, and the effects of withdrawals and sewering on the aquifer system.
5. Water quality and some general water-chemistry information represented as figures and/or graphs and possibly emerging contaminants in groundwater and/or areas of saltwater movement. Also using maps to show locations of wastewater treatment plants that discharge to groundwater and areas served by residential septic systems.
6. The groundwater system represented as figures and tables showing seasonal and annual changes using selected groundwater and streamflow monitoring
7. References
It is hoped that such resources will provide the information needed to inform the public on the current state of the aquifer so that sound water-management decisions can be made.
