Abstract

Treyburn is a 5,400 acre planned, mixed-use community located in the Falls Lake watershed in the upper Neuse River Basin of North Carolina. From February 1988 through 1993, hydrologic-data were collected at 17 study sites in or near the Treyburn development to compare the effects of varying types of land-use development on the water-quality of streams flowing in or near the development. The collected hydrologic data included measurements of streamflow and concentrations of major dissolved constituents, nutrients, minor elements, and organic compounds. Streamflow in the study basin was approximately 40 percent lower in 1992 and 40 percent higher in 1993 than the long-term annual mean of the long-term discharge records at Flat River in Bahama. Calcium and bicarbonate were the predominant cation and anion at all study sites except one. Mean total nitrogen and phosphorus concentrations at sites in the Treyburn development ranged from 0.5 to 0.8 and 0.03 to 0.10 milligrams per liter, respectively. Total aluminum, iron, and manganese were the metals most frequently detected in the 200 organic compunds analyzed. Dichloro- difluoromethane and methylene chloride were detected most often.
