Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

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.
The New Hope arm of Jordan Lake, located in Chatham County, North Carolina, serves as a drinking-water supply for the Towns of Cary, Apex, and Morrisville. The reservoir is listed as impaired due to nutrient over-enrichment and occasionally experiences algal blooms and fish kills.

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 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).
