(A) Requirements.
(1) Well water testing shall be required for any well installation and maintenance/repair.
(2) Duplicate copies of laboratory test results shall be provided to the owner and the Health Department. The laboratory shall include the State Environmental Protection Agency standards so that it is clear to the layperson whether the water meets standards.
(B) Water testing.
(1) The Health Department shall submit to a certified laboratory a sample of the water from the new or repaired residential well for a laboratory analysis of the following constituents:
(a) Total Coliforms (TC);
(b) E. coli (Only to be tested if well comes back positive for TC);
(c) Nitrates; and
(d) Arsenic (newly driven wells only);
(2) The permitting fee for a new well shall include the cost of this initial testing. Further testing that may be required will be the responsibility of the well owner.
(C) Fees. Fees for well testing shall be included in the permitting fees. Permitting fees will be in accordance with the most recent County Health Department Fee Ordinance Schedule.
(D) State and federal limits. All wells shall be required to be in compliance with all standards of the state and the Environmental Protection Agency for wells and drinking water.
(E) Disinfection. To prevent contamination of the well or aquifer, it is desirable to maintain a chlorine residual of 200 parts per million or similar antibacterial chemicals in the well hole all during the drilling process. Under these conditions the well need not be disinfected until the pump is set. Every new, modified or reconditioned water source, including pumping equipment and gravel used in gravel wall wells, shall be disinfected before being placed in service for general use. Such treatment shall be performed both when the well work is finished and when pump is installed or reinstalled. If there is no significant lapse of time between the two operations, only the latter disinfection will be required. The casing pipe shall be thoroughly swabbed to remove oil, grease and joint dope, using alkaline if necessary to obtain clean metal surfaces. The well or other groundwater development equipment, including the pumping equipment and gravel used a gravel well construction shall be disinfected with a solution containing enough chlorine to leave a residual or 25 parts per million in the well after a period of at least 24 hours.
(F) Approval required. The water from a new well shall not be used for human consumption until such time as the well has been approved by the Health Officer and the water analysis is acceptable to the Health Officer.
(G) Sampling faucets. In all pressure water systems provisions shall be made for collection of water samples by the installation of a smooth bore sampling faucet on the discharge side of and as close as possible to the pump prior to the bladder tank. Sampling faucets shall be turned down position.
