Disinfection and Other Sanitary Requirements. (a) All newly constructed wells or existing wells subjected to any repair work shall be disinfected before being placed in service. A chlorine solution of approximately 100 mg/l of available chlorine in the well water is normally adequate. The solution shall be introduced into the well in such a manner that all surfaces above the static level will be completely flushed with the solution. The well contents should then be agitated to uniformly distribute the chlorine throughout the well. The chlorine solution shall remain in the well for not less than 24 hours. The chlorine residual should be monitored to insure adequate concentration. Before providing water for consumptive use, the well shall be flushed until all traces of chlorine have been removed. After flushing the residual chlorine from the well, a water sample shall be collected for bacterial analysis. If the coliform bacteria test is positive (i.e., one or more counts per 100 ml), the well shall be disinfected again as prescribed above. Water samples shall then be placed into operation until the well has been adequately disinfected as demonstrated by testing. (b) Gravel. Gravel used in gravel-packed wells shall come from clean sources and should be thoroughly washed and disinfected by hypochlorite treatment before being placed in the well. Gravel purchased from a supplier should be washed free of silt, and other foreign materials prior to delivery to the well site. Crushed rock shall not be used. (c) Drilling Fluid. Only fresh water shall be used in drilling fluids whether employed alone or in combination with drilling additives. Only high grade clays or 22 GAR - GEPA DIV. II - WATER CONTROL APPENDIX A CH. 7 - WATER RESOURCE DEVELOPMENT & OPERATING REGS. - 1997 - P. 37 commercial chemicals, approved by the Administrator, shall be used in the make-up of any drilling fluid. Drilling fluid with a mixture of water and unprocessed mud, clay, or other material will not be permitted. Drilling fluid shall not impart any toxic substances to the water or promote bacterial contamination. Drilling fluid ejected from the well during drilling operation must be contained on-site or disposed off as directed by the Administrator. (d) The premises, materials, tools and drilling equipment shall be maintained so as to minimize contamination of the underground water during the drilling operation. (e) Disinfection of Non-flowing Wells. (1) Method A. Where practical, the standard concentration chlorine solution used to disinfect the well should be prepared in the surface in containers having a volume equal to at least twice the volume of water contained in the well. This prepared solution should then be rapidly discharged into the well, care being taken to flush the walls above the water level. (2) Method B. Instead of preparing the standard concentration chlorine Solution in containers, a stock chlorine solution of 15,000 mg/l could be added to a continuous flow of water into the well to provide the standard-chlorine concentration. Either of the above methods will carry the chlorinated water into the voids of the water-bearing formation and should provide effective treatment if the chlorinated water is applied rapidly enough to reach all formations penetrated by the well or is introduced at different levels in it. (3) Method C. If methods A and B are not practical, stock solution may be added to the well, preferably at different levels, to provide the standard concentration in the, water contained in the well. The well should then be agitated with a bit, bailer, or test pump to spread the chlorine solution throughout the water. (4) Method D. Instead of using liquid chlorine solutions, a perforated pipe container capped at both 22 GAR - GEPA DIV. II - WATER CONTROL APPENDIX A CH. 7 - WATER RESOURCE DEVELOPMENT & OPERATING REGS. - 1997 - P. 38 ends, containing hypochlorite tablets may be moved up and down in the wall by means of a weighted cable. Sufficient compound should be applied to provide the standard concentration. (f) Disinfection of equipment and material used in well. (1) If the well is disinfected prior to the insertion of the test pump all exterior parts of the test pumps coming in contact with the water must be cleaned, wetted, and dusted with a powdered chlorine compound. If possible, at the start of the operation of the pump, the pump discharge be so regulated that some of the chlorinated water maybe returned to the well. (g) Chlorine Solution. A stock solution of chlorine may be prepared by dissolving fresh chlorinated lime, hypochlorite tablets, or other chlorine compounds in water in the proportion of 4 oz (113.4 g) of available chlorine to 1 gal. (3.79 L) of water. This gives a chlorine concentration of 30,000 mg/l or 3.0 percent, by weight. To obtain an applied standard concentration of 100 mg/1, 1 gallon (3.79 L) of stock solution is used to treat 300 gallons (1136 L) of water. Table 1 shows the number of ounces of chlorine compounds of a given available chlorine content (generally marked on the outside of the can or package) required for the effective disinfection of the well can be computed by the use of Table I together with Table 2, showing the contents in gallons per foot of wells of various diameters. Volume of water for various size wells is shown in Table 3.

In this event, the well shall be properly maintained at the expense of the Agency according to the provisions specified in the §7127(d) of this Section. (f) All wells declared as being “abandoned wells" shall be properly destroyed in accordance with §7128. §7128. Requires for Destruction of Abandoned Wells. (a) All “abandoned" wells, including test holes, shall be destroyed by their owner in such a way that they will not produce water or act as a channel for the interchange of waters, when such interchange will result in a water bearing formations penetrated, or present a hazard to the safety and well being of people and animals. (b) Before the hole is filled, the well shall be investigated by a licensed well driller to determine its condition, details of construction, and whether there are obstructions that will interfere with the process of filling and sealing. (1) If there are any obstructions, they shall be removed if possible, by cleaning out the hole or by redrilling. (2) Where necessary, the insure that sealing material fills not only the well casing but also any annular space or nearby voids, the casing should be removed (if possible), perforated, or otherwise punctured, prior to placing the sea ling material. (c) The following are requirements for filling and 22 GAR - GEPA DIV. II - WATER CONTROL APPENDIX A CH. 7 - WATER RESOURCE DEVELOPMENT & OPERATING REGS. - 1997 - P. 48 sealing when certain conditions have been found to exist as established through inspection by the Administrator. (1) When the well is wholly situated in unconsolidated material in an unconfined groundwater zone. If the groundwater is within fifty (50) feet of the surface, the upper twenty (20) feet shall be sealed with impervious material and the remainder of the well shall be filled with clay, sand, or other suitable inorganic material. (2) Well penetrating several aquifers or formations. In all cases the upper twenty (20) feet of the well shall be sealed with impervious material. In areas where the interchange of water between aquifers will result in a deterioration of the quality of water in one or more aquifers, or will result in a loss of artisan pressure, the well shall be filled and sealed so as to prevent such interchange, and or other formations where impervious sealing material is not required. Impervious material must be placed opposite confining formations for a sufficient vertical distance (but no less than 10 feet) in either direction, or in the case of “bottom water", in the upward direction. (3) Well penetrating crevice or fractured rock. If creviced or fractured rock formations are encountered just below the surface, the portions of the well opposite this formation shall be sealed with neat cement, cement grout, poz-mix cement grout, or concrete, alternate may be used to fill the well. Fine grained material or fractured rock formations. (4) Well in noncreviced, consolidated formation. The upper twenty (20) feet of a well in a noncreviced, consolidated formation shall be filled with impervious material. The remainder of the well may be filled with clay or other suitable inorganic material. (5) Well penetrating specific aquifers, local conditions. Under certain local conditions, the Administrator may require the specific aquifers or formations be sealed off during destruction of the well. 22 GAR - GEPA DIV. II - WATER CONTROL APPENDIX A CH. 7 - WATER RESOURCE DEVELOPMENT & OPERATING REGS. - 1997 - P. 49 (d) The following requirements shall be observed in placing fill or sealing material in wells to be destroyed: (1) The well shall be filled with the appropriate material (as described in this Section) from the bottom of the well up. (2) Where neat cement grout, portland cement grout, poz-mix cement grout or sand-concrete grout is used, it shall be placed in one continuous operation. (3) Sealing material shall be placed in the interval or intervals to be sealed by methods that prevent free fall, dilution, and/or separation of aggregates from cementing materials. (4) Where the head (pressure) producing flow is great, special care and special methods must be used to restrict the flow while placing the sealing material. In such cases, the casing must be perforated opposite the area to be sealed and the sealing material forced out under pressure into the surrounding formation. (5) When pressure is applied to force sealing material into the annular space, the pressure shall be maintained for a length of time sufficient for the cementing mixture to set. (6) To assure that the well is filled and that there has been no jamming or “bridging“ of the material, verification shall be made that the volume of material placed in the well installation at least equals the volume of the empty hole. (e) Materials. Requirements for sealing and fill materials are as follows: (1) Impervious Sealing Materials. Sealing materials shall have such a low permeability that the volume or water passing through them is of small consequence. Suitable materials include neat cement grout, portland cement grout, poz-mix-cement grout, and sand-cement grout, and native soils and natural material that have a co-efficient of permeability of less than one hundred (100) feet per year, used drilling muds are not acceptable. (2) Fill Material. Many materials are suitable for use as a filler in destroying wells. These include clay, 22 GAR - GEPA DIV. II - WATER CONTROL APPENDIX A CH. 7 - WATER RESOURCE DEVELOPMENT & OPERATING REGS. - 1997 - P. 50 silt, sand, gravel, crushed stone, native soils, mixtures of aforementioned types, and those described in §7128(e)(1). Material containing organic matter shall not be used. (f) Additional Requirements for Abandonment of Wells in Urban Areas. In areas developed for multiple habitation, to make further use of the well site, the following additional requirements must be met: (1) A hole shall be excavated around the well casing to a depth of a six (6) feet below the ground surface and the well casing removed to within six (6) inches of the bottom of the excavation. (2) The sealing material used for the upper portion of the well shall be allowed to spill over into the excavation to form a cap at least one (1) foot thick. (3) After the well has been properly filled, including the sufficient time for sealing material in the excavation to set, the excavation shall be filled with native soil. (g) Temporary Cover. During periods when no work is being done on the well, such as overnight or while waiting for sealing material to set, the well and surrounding excavation, if any, shall be covered. The cover shall be sufficiently strong and securely anchored to prevent the introduction of foreign material into the well ad to protect the public from a potentially hazardous situation. (h) The Administrator shall set a compliance schedule for the sealing of abandoned wells and shall notify, in writing, the owner of the wells to be destroyed. The administrator reserves the right to require the owner to replug any well where it can be determined that the previous plugging was not effective due to failure of cement seal or other causes. (i) Inspection of destroyed wells after Sealing or Filling. The owner shall notify the Administrator forty eight (48) hours in advance of his intent to commence work. All destroyed wells shall be inspected during and after sealing or filling operation, by the Administrator or 22 GAR - GEPA DIV.
