Samples of groundwater discharging into
the Neuse River adjacent the Neuse River Wastewater
Treatment Plant (NRWWTP) waste application fields (WAFs)
have been measured as high as 86 mg NO3/L. The NC surface
water standard is 10 mg NO3/L. Geophysical surveys of the
WAFs revealed diabase dikes intruded into the bedrock.
Groundwater flow is occluded across the dikes; however,
fractures along the dikes are likely areas of high
groundwater flow. At the NRWWTP, four sampling periods were
