Each monitoring well shall be developed such that the level of turbidity or settleable <br /> solids does not preclude accurate chemical analyses of any fluid samples collected <br /> or adversely affect the operation of any pumps or pumping equipment. <br /> C. GEOTHERMAL WELLS <br /> 1. Geothermal well construction standards, installation standards and contractor <br /> certification procedures adopted by the International Ground Source Heat Pump <br /> Association (IGSHPA) are hereby enacted by reference.A copy of the IGSHPA <br /> standards and procedures is available at the Environmental Health Division of the <br /> Orange County Health Department. <br /> 2.The well shall be constructed in such a manner that surface water or contaminants <br /> from the land surface cannot migrate along the borehole annulus either during or <br /> after construction. Prior to removing equipment from the site, the borehole shall be <br /> protected to prevent the introduction of contaminants into the well. <br /> 3. Geothermal wells shall meet the horizontal setback standards as specified in Section <br /> II (A)of these Rules. <br /> 4. For closed loop geothermal wells that are fully grouted with an approved grout, the <br /> following setbacks shall apply as measured from any portion of the borehole to the <br /> potential source of contamination: <br /> a) Building perimeters, including any attached structures 15 ft <br /> b)Septic tanks and drainfields, including drainfield repair areas 50 ft <br /> c) Sewer lines constructed to water main standards 15 ft <br /> d)Sewer lines not constructed to water main standards 25 ft <br /> e) Land-based or subsurface waste storage or disposal systems 50 ft <br /> 5. Geothermal wells shall meet construction specifications in Section II of these <br /> Rules, however closed loop geothermal heat exchange injection wells constructed <br /> and completed according to International Ground Source Heat Pump Association or <br /> equivalent standards shall not be required to be constructed with casing. <br /> 6. Only additives which are deemed not to adversely affect human health by the <br /> Department shall be used. <br /> 7.
