In such installations where Class I or II wells (as per Section 1040.12(b) of this chapter) are constructed, the distance between the potential sources of pollution may be reduced, provided that geological conditions indicate that such would be satisfactory and in accordance with the Division of Engineering, State Health Department, standards for location of public supplies in relation to potential sources of pollution. | ||

The minimum distance shall be reduced by up to 50% if a Geophysical Study is conducted in accord with the County's Facilities Standards Manual and such study concludes that the risks of collapse and groundwater contamination are non-existent or insignificant for the proposed location and use, except that no reduction shall be allowed for any Perennial Sinking Stream, nor for any Cave Openings, nor for any Sinkhole/Swallet/Closed Depression that receives an intermittent or Perennial Sinking Stream, nor for any rock outcrop.
In addition, water supply systems and wells are prohibited within 1) one hundred (100) feet from a spring, measured from the first emergence of the spring or 2) two hundred feet when the first emergence of the spring is on a slope greater than 15% and is downslope from the water supply system or well, as applicable.
*All minimum distances listed in Table IA must be met in addition to the minimum distances set forth in Table I.
