According to OWASA and the North Carolina Department of Environmental Health and Natural <br /> Resources (NCOEHNR), there has been no water sampling, chemical analysis, or benthic surveys <br /> conducted on Phil's Creek near the quarry site. <br /> OWASA has, however, sampled Phil's Creek as part of an agricultural water quality survey during <br /> the months of September and October, 1991 south of the quarry site. The sampling locations <br /> were at Neville Road and just above the Phil's Creek confluence with Neville Creek. The results <br /> of these analyses concluded that for the parameters tested, no apparent effect upon water quality <br /> could be attributed to upstream quarry or asphalt plant operations. <br /> Water samples from the Quarry Reservoir collected by OWASA periodically between 1988 and <br /> 1991 were analyzed for 49 volatile and synthetic organic chemicals. In no instance were any of <br /> these substances measurable above their analytical detection limits of 0.5 parts per billion. <br /> Downstream water and bottom sediment from University Lake have been collected periodically <br /> since 1988 by the US Geological Survey through OWASA's participation in the Triangle Area <br /> Water Supply Monitoring Program. Samples have been analyzed for numerous metals, <br /> pesticides, herbicides, volatile and other synthetic organic compounds. Virtually all substances <br /> have been below the limits of detection in water samples. Trace amounts of certain pesticides <br /> and other organic residuals have been measured in bottom sediments, but in no cases have <br /> these occurred at concentrations above background levels measured elsewhere in the Triangle <br /> Area. <br /> Environmental monitoring efforts undertaken in the Quarry Reservoir, Phil's Creek, and University <br /> Lake have revealed no water quality effects attributable to the existing quarry or asphalt plant <br /> operations. <br /> B.
