(a) Construction and Performance Characteristics. A report shall be made on each well tested in accordance with Appendix IV following this chapter, and such report shall be supplied to the owner and the Health Department by the well driller. Pump test results shall be supplied to the owner and the Department by the pump installer. Such report shall include, at a minimum, the following:
(1) The type, diameter and length of the casing;
(2) The total depth of the well;
(3) The type, diameter and length of the strainer, if any, and the size of screen openings;
(4) The method of sealing the top and bottom of the screen;
(5) The standing (static) water level, that is, the water depth below the ground surface when not pumping;
(6) The yield of the well in gallons per minute, and the elevation of the water surface when pumped at the designated rate, if a pump test is required;
(7) The number of hours the pump is operated at a stipulated rate during the pumping test, if required;
(8) A record of any other pumping performance;
(9) A log and samples of materials encountered during drilling when requested, collected in accordance with Appendix IV;
(10) The physical appearance of the water at the end of the final pumping test; and
(11) The results of analytic tests made to determine potability by the well pump installer, licensed driller or certified professional geologist.
(b) Protection of Wells. Wells under construction or repair shall be protected at all times so as to prevent any drainage or foreign matter from entering the casing. When drilling operations are suspended, as overnight, the casing shall be securely covered or capped. Upon completion of drilling, a secure cap or plug shall be placed on or in the top of the casing. Water used for drilling operations or for tempering or cooling of well tools shall be of approved potable quality.
(c) Disinfection. Upon completion of construction and/or repairs of any water supply system, or following repairs to the pumping equipment, it shall be disinfected and flushed, as provided in Section 1040.16.
(d) Nonacceptable Equipment. No pitcher, split-base or chain bucket pump shall be installed on any water supply system.
(e) Cross Connections. No water service connection shall be made to a frostproof toilet. Where frostproof hydrants are used, adequate draining shall be provided to prevent possible backflow. The ditch excavation between the well and pressure tank is not adequate drainage. There shall be no cross connection between a private water supply system and any other private or public water supply system.
(f) Abandoned Wells. No person shall use an abandoned or unused well for the purpose of disposal of sewage, sewage effluent or other polluting material. The owner of any permanently abandoned well shall immediately fill and/or seal the well with cement or bentonite clay or other equally suitable material under supervision of the Health Director. Permanent abandonment occurs when a well is no longer in active use and/or when the construction of the well no longer meets the requirements of this chapter. As used in this subsection, “immediately” means within forty-eight hours of drilling completion if the well to be abandoned yields insufficient water, or within thirty days if a previously constructed and operational well is abandoned.
(g) Chemical or Physical Alteration of Wells After Drilling.
(1) Hydraulic fracturing of wells may be permitted by the Director of Health under Section 1040.06 and shall be considered on a case by case basis.
(2) No person shall use explosives in wells.
(3) The use of chemical and biological additives to remove pollutants and/or to improve well yields may be permitted by the Director under this chapter and shall be considered on a case by case basis except that the use of such additives shall not be permitted within the Limestone Overlay District.
(h) Drilled Wells Constructed in the Bottom of Dug or Bored Wells. A drilled well constructed in the bottom of a dug or bored well shall not be approved.
