New systems located within areas that are determined to have a potential for nitrogen contamination in the groundwater due to dense development greater than one (1) dwelling unit (or equivalent) per gross acre on average, and soils with a percolation rate five (5) minutes per inch or faster (coarse to medium sand) and groundwater levels less than 8 (eight) feet below the bottom of the proposed dispersal field and where individual water wells are the source of water supply, the Director of Environmental Health shall require nitrogen reducing supplemental treatment unless cumulative impact studies determine that the groundwater will not be affected.
