Map of ongoing project locations in U.S. National Parks, Assessing Endocrine Disrupting Chemicals Risk
January 24, 2017

Endocrine disrupting chemicals (EDC) threaten the reproductive success and long-term survival of sensitive aquatic populations in the U.S. National Park Service (NPS). The project employs a standardized EDC risk assessment framework to link new and ongoing research efforts in individual Parks and in Park Monitoring Networks, in order to provide a service-wide assessment of EDC risk in the NPS.

Map of groundwater monitoring locations in Moore County, NC.

As part of the cooperative groundwater study between the USGS and Moore County, a network of monitoring-well sites with groundwater-level recorders was established at selected available locations in Moore County. 

The Atlantic Coastal Plain along the Atlantic Coast of North and South Carolina and parts of northern Florida, Georgia, Virginia
December 13, 2016

The Atlantic Coastal Plain aquifers and confining units of South Carolina are composed of crystalline carbonate rocks, sand, clay, silt, and gravel and contain large volumes of high-quality groundwater. The aquifers have a long history of use dating back to the earliest days of European settlement in the late 1600s. Although extensive areas of some of the aquifers have or currently (2015).

map of beach status of Lake Ontario and Lake Erie in New York
November 9, 2016

New York Nowcast predicts water quality conditions at select beach swimming areas in NY. The Nowcast estimates conditions by merging environment and climate data with variables measured at a beach by 8 AM each morning and entering them into a computer program which provides a probability from 1 to 100 as to whether or not the beach has exceeded the bathing-water standard of 235 units of E. coli.
