Surface-water and water-quality data from selected streams and treated waters in the Greensboro area, North Carolina, 1986-87
Open-File Report 88-169
By M.S. Davenport
Abstract
Water and bottom-sediment samples were collected from April 1986 to September 1987 at 19 sites in Guilford County and the City of Greensboro, North Carolina. Sampling locations included 13 stream sites, two lakes that supply City of Greensboro drinking water, two City of Greensboro finished drinking-water filtration plants, and two municipal wastewater plants where effluents were sampled prior to outfall into the receiving streams. Water sampling consisted of six routine samplings during various stages of steady flow at all sites, and rainfall-event sampling during two storms at six sites. Bottom-sediment samples were collected at three sites during two routine samplings.
Samples were analyzed for trace-element, major ion, and nutrient concentrations, as well as general water-quality indicators, such as pH, dissolved oxygen, and specific conductivity. Concentrations of acid and base/neutral extractable, volatile organic compounds, and organochlorine and organophosphorus constituents were also determined. Chromatographs from organic analyses were submitted to computerized library searches, the results of which are included in this report. Results from all analyses are presented in tabular form in the appendices.
