Stratification and Water Quality of Jordan Lake, North Carolina

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.In order to evaluate effects of installing a vertical-mixing system on the New Hope arm of Jordan Lake, the U.S...

Triangle Area, NC, Water Supply Monitoring

The Research Triangle area, located within the upper Cape Fear and Neuse River basins, is one of the most rapidly developing areas in the Nation. Growth has increased demand for water from public suppliers, the majority of which draw water from streams and lakes in the region. Growth also brings the threat of greater loads of contaminants and new contaminant sources that, if not properly managed...

Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989–2013

As the population of the Triangle area in central North Carolina increases, the demand for good quality drinking water from streams and lakes within the upper Neuse and upper Cape Fear River Basins also increases. The Triangle area includes Raleigh, Cary, Research Triangle Park, Durham, Chapel Hill, and the surrounding communities. The U.S. Geological Survey examined temporal trends in water quali

Occurrence and distribution of mercury in streams and reservoirs in the Triangle Area of North Carolina, July 2007–June 2009

During the time period 2001–2006, the U.S. Geological Survey reported mercury-concentration measurements that exceeded the North Carolina water-quality criterion (NCWQC) of 0.012 microgram per liter for total recoverable mercury in streams and reservoirs across the Triangle Area of North Carolina. Mercury data were sparse, however, generally consisting of only one or two water samples per year. Ad
