around the outside of the well casing to a depth not less than three feet below the <br /> ground surface. The well casing shall then be cut off six inches above the bottom of <br /> this excavation and removed. During the sealing operation, the grout used to fill the <br /> well shall be allowed to spill over into the excavation and fill it for a thickness of one <br /> foot and form a cap which has a diameter of at least one foot greater than the <br /> diameter of the originally drilled hole. This procedure should result in the exposed <br /> edge of the casing being covered with six inches of grout. After the sealing operation <br /> and the sealing material has set, the excavation shall be back filled with clean native <br /> soil. <br /> 6.3.7. Under no circumstances shall an abandoned well be used for disposal of any solid or <br /> liquid wastes. <br /> 6.3.8. If a test hole is drilled for construction of a well, and is not used in the final <br /> construction of the well, the test hole shall be destroyed from the total depth to the <br /> surface and under inspection. <br /> 7. INSPECTION OF WELLS <br /> 7.1. Approval of the application for permit will be withheld until an onsite inspection is made, if <br /> necessary, and the requirements regulating the well location are met. <br /> 7.2. Inspections will be made to ensure compliance with these Standards during and after well <br /> construction, destruction, deepening, reconditioning, subsurface borings, seismic test holes, <br /> monitoring wells, geophysical/geotechnical wells, cathodic protection wells, injection wells, <br /> recharge wells, extraction wells and other wells. <br /> 7.3. Final inspection of the well surface seal, sanitary seal, check valve, sample tap, and/or pump <br /> including the use of food grade lubricants, shall be made after the pump is installed and <br /> operating. <br /> 7.4. The permit applicant shall provide a minimum of 24-hour advance request for all required <br /> inspections. <br /> 7.5. Other inspections will be made as deemed necessary by the Director. <br /> 8. DISINFECTION OF WELLS <br /> 8.1. Following initial installation or subsequent repairs, all public and individual domestic water wells <br /> and all appurtenances shall be disinfected by a method approved by the Director. <br /> 8.2. To disinfect new wells,-the required amount of disinfectant shall be placed in the well and the <br /> well surged with the pump several times to mix the disinfectant with the water. The well should <br /> remain idle for a minimum of 24 hours and then be pumped until free of disinfectant. When <br /> placing the disinfectant in the well, a solution of the disinfectant shall be used to wash down the <br /> well casing and drop pipe. <br /> 13 <br />
