“…Total nitrogen concentrations in water that drains from the Treyburn development are equal to (site 8T) or slightly greater (sites 2T and 3T) than the background value. Total mean nitrogen concentrations from the Treyburn development sites also are substantially less than total mean nitrogen concentrations reported in other streams in the Falls Lake watershed (Garrett, 1994).…”

“…Physical and chemical stream characteristics of the sampling sites were reviewed prior to project design using several U.S. Geological Survey and U.S. Environmental Protection Agency surveys (Hamilton and Shedlock, 1992;Khorram et at., 1992;Garrett et at., 1994). Vulnerable aquifers and relative intensities of use for particular pesticides in North Carolina were identified (Moreau, 1990).…”

Studies were conducted to analyze the presence of 11 pesticide residues in 12 surface waters in the Piedmont and coastal plain regions of North Carolina. Samples were assayed using enzyme-linked immunosorbent assays (ELISAs). All ELISA results of one part per billion (ppb, pgfL) or greater were confirmed using gas chromatography/mass spectrometry (GCIMS). ELISA detection limits were approximately an order of magnitude higher than GCJMS methods. Of the 5,035 analytical results from 742 surface water samples, atrazine was detected in approximately 45 percent of the samples, five of which were at or above the Maximum Contaminant Level (MCL) of 3-ppb. Metolachlor was detected in 64 percent of the samples. Aldicarb, 2,4-D, chlorpyrifos, and chlorothalonil were also detected, and each was found in less than 12 percent of the samples. The remaining pesticides, including carbaryl, acetochior, methomyl, carbofuran, and alachlor, were not detected during the study period.

Surface-water supplies are important sources of drinking water for residents in the Triangle area of North Carolina, which is located within the upper Cape Fear and Neuse River Basins. Since 1988, the U.S. Geological Survey and a consortium of local governments have participated in a cooperative effort, known as the Triangle Area Water Supply Monitoring Project, to track water-quality and quantity conditions in several of the area's water-supply reservoirs and streams. This report summarizes the hydrologic and water-quality monitoring activities through this cooperative effort, including an overview of previous and current data collection and qualityassurance and quality-control activities.
