Recent environment concerns regarding hog production in Niorth Carolina was the precusor for House Bill 6053. Bill 6053 directed North Carolina State University to determine the extent in whichj animal waste lkagoons pose athreat, if any to ground water in the state. Samples were taken from shallow ground water at 125 fyt from the laggon, and any available surface water were also sampled. The results indictaed approximately 65% of the groundwater has seepage losses sufficient enough to exceed the NO3-N drinking water stamndard of 10 ppm at 125 ft from the lagoon. Approximately 38% of the sites show strong plumes, sufficient enough to adversely impact downgradient discharge. Only 16 of the 34 locations had surface water nearby. Of these 16 locations seven did not show a apparent N enrichment, therefore 8 locations showed N enrichment that might be a result of lagoon seepage, however onlyt one was most likely to be created by seepage.
