NR 812.20(2)(c) (c) The grout shall be placed in one continuous operation, if possible. It is the well or heat exchange driller's or well constructor's responsibility to ensure that all necessary materials are on the job site. If unforeseen circumstances prevent completing the cement grouting work in one continuous operation, the well or heat exchange driller or well constructor shall report the non-continuous grouting operation and the reason for it on the construction report for the well.
NR 812.20(2)(d) (d) When a conductor (tremie) pipe is used, the bottom end shall be kept submerged in the grout throughout the grouting process.
NR 812.20(2)(e) (e) The grout shall be brought up to the ground surface. The density of the grout flowing from the annular space at the ground surface shall be the same as the density of the grout being placed. Any settling of the grout more than 6 feet below the ground surface shall be made up. The well driller or well constructor shall add grout until it comes back up to the ground surface.
NR 812.20(2)(f) (f) When temporary outer casing is used to construct the upper enlarged drillhole an attempt shall be made to remove the temporary outer casing during or after the grouting process. If possible, it shall be removed. The grout level shall be retained above the bottom of the casing during removal of the casing.
NR 812.20(2)(g) (g) When an upper enlarged drillhole has been constructed to accommodate the setting and removal of temporary outer casing, the annular space between the temporary outer casing and the well casing pipe shall be grouted before the temporary outer casing is pulled. After the grout between the temporary outer casing and the well casing pipe flows at the ground surface the annular space outside the temporary outer casing shall be grouted by placing a tremie pipe to the bottom of the outer annular space. The grout shall flow at the ground surface before the temporary outer casing is pulled.
NR 812.20(2)(h) (h) The well driller or well constructor shall allow the grout to set for at least 12 hours before commencing further well construction.
NR 812.20(2)(i) (i) Prior approval is required for the use of the “Halliburton" grouting methods and the “grout displacement" grouting method when the upper enlarged drillhole is more than 200 feet deep or when drilling mud or bentonite slurry has not been circulated up to the ground surface in the annular space prior to grouting.
NR 812.20(2)(j) (j) The “conductor (tremie) pipe-gravity" method is not an approved pressure method of grouting. All other methods described in sub. (3) are approved pressure methods for cement grouting and sealing and shall be used when neat cement grout is required to seal the annular space when the upper enlarged drill- hole is less than 4 inches larger in diameter than the nominal diameter of the well casing pipe or when the upper enlarged or heat exchange drillhole extends greater than 25 feet deep or when the heat exchange drillhole is less than 25 feet deep.
NR 812.20(3) (3)Cement grout placement methods. This subsection describes approved cement grout placement methods.
NR 812.20(3)(a) (a) Conductor (tremie) pipe-gravity. As depicted in figure 11, grout material may flow by gravity through a funnel or hopper connected to a conductor pipe. The conductor (tremie) pipe shall be lowered to the bottom of the annular space to be grouted and the grout material placed from the bottom up. The end of the conductor pipe shall be kept submerged in the grout at all times. This method may be used only when the upper enlarged drillhole is at least 4 inches larger in diameter than the nominal diameter of the well casing pipe and is less than 100 feet deep or when the heat exchange drillhole is less than 25 feet deep. The grout shall flow at the surface with the same consistency as the grout entering the well.
NR 812.20(3)(b) (b) Conductor (tremie) pipe-pumped. As depicted in figure 12, the grout material shall be placed by a pump through a conductor pipe into the annular space between the well casing pipe and the upper enlarged drillhole wall or inside surface of the temporary outer casing or a heat exchange drillhole. The minimum diameter of the upper enlarged drillhole shall be as specified in Tables I to IV. The conductor pipe shall be lowered to the bottom of the annular space to be grouted and the grout material shall be pumped from the bottom up. The end of the conductor pipe shall be kept submerged in the grout at all times and the conductor pipe shall be maintained full of grout. The grout shall flow at the surface with the same consistency as the grout entering the well.
NR 812.20(3)(c) (c) Grout (float) shoe-continuous injection. As depicted in figure 13, the bottom of the well casing pipe shall be fitted with a grout (float) shoe equipped with a back pressure (check) valve. A conductor pipe or drill stem shall be connected to the grout shoe and shall extend up through the well casing pipe to a grout pump at the ground surface. The well casing pipe shall be suspended a short distance above the bottom of the upper enlarged drillhole. Grout material shall be pumped through the conductor pipe and the grout shoe until the entire annular space is filled with grout. The conductor pipe or drill stem shall then be removed. The well casing pipe shall be set to the bottom of the upper enlarged drillhole. The grout material shall be allowed to set for at least 12 hours. Once set, the grout shoe and back pressure valve may be drilled out and the well construction continued.
NR 812.20(3)(d) (d) Well seal/tremie pipe-pumped (Braden-head method). As depicted in figure 14, the well casing pipe shall be suspended a short distance above the bottom of the upper enlarged drillhole. The well casing pipe and annulus shall be filled with water, drilling mud or bentonite slurry. A conductor (tremie) pipe shall be set inside the well casing pipe to the bottom and shall extend watertight through a sanitary well seal installed securely in the top of the well casing pipe. A packer may be installed inside the well casing pipe, at depth, as an alternative to using a well seal at the top. The grout shall be pumped down the conductor pipe and up the annular space. The grout shall flow at the surface with the same consistency as the grout entering the top of the conductor pipe. Immediately following grout flow at the surface, the well casing pipe shall be set to the bottom of the upper enlarged drillhole of an unconsolidated formation well or driven to a firm seat in a bedrock well.
NR 812.20(3)(e) (e) Halliburton (double plug) method. This method may only be used when the upper enlarged drillhole is less than or equal to 200 feet deep or when drilling mud or bentonite slurry has been circulated in the upper enlarged drillhole from the bottom up to the ground surface prior to grouting. The grout shall be placed as follows: As depicted in figure 15, the well casing pipe casing shall be suspended a short distance above the bottom of the upper enlarged drillhole. A drillable spacer plug shall be inserted into the well casing pipe and the top of the well casing pipe sealed watertight. A measured volume of grout, calculated to be of adequate quantity to seal the annular space, and to fill the bottom 10 to 15 feet of well casing pipe shall be pumped into the well casing pipe through a small diameter pipe extending watertight through the well seal. The well casing pipe shall then be opened and a second plug inserted on top of the grout and the top of the well casing pipe resealed. A measured volume of water, calculated to fill the well casing pipe except for the bottom 10 to 15 feet, shall be pumped into the well casing pipe, pushing the second plug to within 10 to 15 feet above the bottom of the well casing pipe and pushing most of the grout from the bottom of the well casing pipe up into the annular space. As an alternative, a drill stem may be used to push the top plug down to near the bottom of the well casing pipe. For this alternative, the plug may not be attached to the drill stem. If the bottom plug used is longer than the gap between the bottom of the suspended well casing pipe and the bottom of the upper enlarged drillhole, it is not necessary to pump in a measured volume of water. A conductor (tremie) pipe shall be available at the drill site in case the grout does not flow at the ground surface. The water pressure in the well casing pipe shall be maintained for 12 hours until the grout has set and before well construction may continue.
NR 812.20(3)(f) (f) Halliburton (single plug) method. This method may only be used for wells when the upper enlarged drillhole is less than or equal to 200 feet deep or when drilling mud or bentonite slurry has been circulated in the upper enlarged drillhole from the bottom up to the ground surface prior to grouting. As depicted in figure 16, the grout shall be placed as follows: The well casing pipe shall be suspended a short distance above the bottom of the upper enlarged drillhole. A measured volume of grout, calculated to seal the annular space and to fill the bottom 10 to 15 feet of well casing pipe shall be pumped into the well casing pipe through a small diameter pipe extending watertight through the well seal. A drillable spacer plug shall be inserted into the well casing pipe and the top of the well casing pipe sealed watertight. A measured volume of water, calculated to fill the well casing pipe except for the bottom 10 to 15 feet shall be pumped into the well casing pipe, pushing the plug down to about 10 to 15 from the bottom of the well casing pipe and most of the grout from the bottom of the well casing pipe up into the annular space. A landing collar should be installed near the bottom of the well casing pipe to prevent the plug from being forced out the bottom. As an alternative a drill stem may be used to push the plug down. For this alternative the plug may not be attached to the drill stem. If the plug used is longer than the gap between the bottom of the suspended well casing pipe and the bottom of the upper enlarged drillhole, it is not necessary to pump in a measured volume of water. A conductor (tremie) pipe shall be available at the drill site in case the grout does not flow at the ground surface. The water pressure in the well casing pipe shall be maintained for 12 hours until the grout has set and before well construction may continue.
NR 812.20(3)(g) (g) Grout displacement method. This method may only be used for wells when the upper enlarged drillhole is less than or equal to 200 feet deep or when drilling mud or bentonite slurry has been circulated in the upper enlarged drillhole from the bottom up to the ground surface prior to the grouting. As depicted in figure 17, a measured volume of grout calculated to be of adequate quantity to seal the annular space plus at least 15% of that volume shall be placed into the upper enlarged drillhole through a conductor (tremie) pipe. The well casing pipe shall be fitted with centering guides and a drillable plug at the bottom and shall be lowered through the grout to the bottom of the upper enlarged drillhole allowing the grout to be forced up into the annular space. If necessary, pressure shall be applied and maintained on the top of the well casing pipe to hold it in place for at least 12 hours or until the grout sets. Water may be added to the well casing pipe to provide extra weight. If the grout does not flow at the ground surface the remainder of the annular space shall be filled with grout placed through a conductor pipe that shall be at the drill site.

NR 812.20(3)(h) (h) Street elbow method. As depicted in figure 18, a small diameter hole is cut through the wall of the well casing pipe near the bottom of the string of well casing pipe. A street elbow is welded watertight through this hole. The male end of the street elbow extends out into the annular space. A ball check valve is threaded into the female end of the street elbow inside the well casing pipe. The top threads on the check valve are “left-handed". A string of conductor (tremie) pipe is threaded into the top of the check valve. The entire string of well casing pipe and conductor pipe are set to the bottom of the upper enlarged drillhole. The grout is pumped down through the conductor pipe and up into the annular space. The grout must flow at the surface with the same consistency as the grout entering the conductor pipe. Immediately following grouting, the conductor pipe is screwed out of the left-hand thread of the check valve and removed. The check valve prevents the grout from moving back inside the well casing pipe. After the grout has set, the drill stem is lowered to the bottom of the inside of the well casing pipe to knock the street elbow off the well casing pipe before well construction continues.
NR 812.20(4) (4)Sodium bentonite water slurry placement methods. When neat cement grout is not required in Tables I to IV and is not to be used, the annular space between any upper enlarged drillhole and the well casing pipe shall be sealed as follows:
NR 812.20(4)(a) (a) When percussion methods are used, following completion of the driving of the well casing pipe, a clay or sodium bentonite and cuttings slurry with a mud weight of at least 11 pounds per gallon shall be placed to permanently fill and seal the annular space. Any subsidence shall be made up. If the upper enlarged drillhole extends below the 40-foot depth, the slurry shall be placed with a conductor pipe.
NR 812.20(4)(b) (b) When rotary methods are used, after the upper enlarged drillhole has been completed by circulating drilling mud, the slurry coming out the top of the annular space shall have a mud weight of at least 11 pounds per gallon before the well casing pipe is set in the drillhole. Any subsidence of the drilling mud and cuttings in the annular space shall be made up. The annular space shall remain filled and sealed up to the ground surface. The rotary method of circulating drilling mud during construction described in this paragraph is an approved pressure method for placing sodium bentonite slurry or drilling mud and cuttings and shall be used when required in Tables I to IV and ss. NR 812.13 to 812.15.

NR 812.22(1)(a) (a) Mechanical surging. A valved or solid plunger surge block may be used to create a surging action in the well. Accumulated material shall be removed periodically. A bailer may be used as the surge block but is usually not as effective.
NR 812.22(1)(b) (b) Air surging. An air compressor and piping may be used to create the surging and jetting action in the well. Water in the well shall be alternately brought to the surface by air lift pumping and allowed to drop back down the well to static condition by shutting the air off. This may be performed with an air-rotary drilling rig and drill stem.
NR 812.22(1)(c) (c) Overpumping. Continuous overpumping at a rate of at least 1 and 1/2 times the design capacity of the well or interrupted overpumping in conjunction with water line drainback to the well in 5-minute cycles may be used.

Clean washed inert, nontoxic material such as sand may be added to the water for the purpose of holding the joints and fractures open after the pressure is reduced. Hydrofracturing may only be performed under the supervision of a well driller. The upper packer may not extend up into the bottom of the well casing pipe nor higher than 40-feet below the ground surface. Hydrofracturing in limestone or dolomite formations may be undertaken only with prior department notification. The well driller shall submit a report on a well construction report form to the department of the results of the hydrofracturing within 30 days following completion.
NR 812.22(3) (3)Well pump test. The well driller or well constructor shall conduct a pump test using the well driller's, the well constructor's or the well owner's pump for each new or reconstructed well to determine the stable yield in gallons per minute, and the water level drawdown. A pump test may be conducted using air-rotary equipment. For flowing wells, the flow rate may be measured using an orifice plate with manometer or equivalent. The static water level and drawdown shall be measured in a stilling pipe when the flow is not adequate for user needs.
NR 812.22 Note Note: A stable pumping water level may not be possible in wells completed in crystalline bedrock.
NR 812.22(4) (4)Well disinfection and batch chlorination. Wells shall be thoroughly disinfected following completion of construction or reconstruction using a chlorine solution such as a sodium or calcium hypochlorite solution. Chlorine compounds having special additives shall not be used.

Thereafter water samples for coliform bacteria and nitrate shall also be collected after the well is entered for the purpose of measuring or diagnosing any feature or problem with the well or for the purpose of installing, replacing or repairing any equipment located within the well or when the casing height is raised. The water samples shall be collected and submitted for analysis no later than 30 days following completion of the well or following completion of any work described above. The well is completed when all operations that require the use of drilling, driving or annular space sealing equipment have been completed. If the water well driller uses the well owner as an agent to collect the water samples, the well driller shall provide the owner with a laboratory designated sample bottle and department specified form. The information submitted on the form shall be complete, true and accurate. If the water well driller uses the pump installer as an agent to collect the water samples, and the pump installer engages in the business of pump installing separately from the water well driller's business, the water samples from each business shall be in separate bottles and each must be submitted to the laboratory with their own department specified forms. Regardless of whether the water well driller delegates the collection and submission of the samples for analysis, the ultimate responsibility to ensure that these tasks are completed belongs to the water well driller. If the water well driller or well constructor is also the pump installer for that well, one set of water samples may be collected following the completion, disinfection and flushing after the pump installation. A water well driller or well constructor is not required to be licensed as a pump installer to install a test pump for well development and water sampling.
NR 812.22(6)(b) (b) The water sample shall be analyzed for coliform bacteria by a laboratory certified by DATCP under ch. ATCP 77 to perform coliform bacteriological analysis of drinking water and having an agreement with the department for electronic submission of laboratory test reports to the department no later than 30 days after completion of the analysis, or be analyzed by the Wisconsin state laboratory of hygiene. The water sample shall also be analyzed for nitrate by a laboratory certified by the department for nitrate analysis of drinking water and having an agreement with the department for electronic submission of laboratory test reports to the department no later than 30 days after completion of the analysis or be analyzed by the Wisconsin state laboratory of hygiene. The certified laboratory and water well driller or well constructor or their agent shall use forms specified by the department.
NR 812.22(6)(c) (c) For any water sample required in a Special Well Casing Depth Area, the analysis shall be performed by a laboratory certified by the department for that analysis and having an agreement with the department for electronic submission of laboratory test reports to the department no later than 30 days after completion of the analysis, or be analyzed by the Wisconsin state laboratory if hygiene. The certified laboratory and water well driller or well constructor or their agent shall use forms specified by the department.
NR 812.22(6)(d) (d) If the laboratory test report indicates that any test result is invalid for any reason, including improper sample bottle, improper collection technique or longer than 48 hours between sample collection and arrival at the laboratory, the water well driller is required to collect replacement samples no later than 30 days after receiving the invalid test report.
NR 812.22(6)(e) (e) The water well driller, well constructor or pump installer shall provide the well owner or the owner's agent with a copy of each laboratory test report no later than 10 days after the well driller's, well constructor's, or pump installer's receipt of the laboratory test reports.
NR 812.22(7) (7)Well and drillhole construction reports.
NR 812.22(7)(a)(a) The water well or heat exchange driller who contracted to construct the water well or heat exchange drillhole, the water well or heat exchange driller who actually constructed the water well or heat exchange drillhole, or the water well or heat exchange drillhole constructor shall submit an original well construction report to the department and to the owner within 30 days following the day the water well or heat exchange drillhole was completed or reconstructed. Heat exchange drillholes require one well construction report for every 20 drillholes drilled, and the well construction report shall include the latitude and longitude of the corresponding drillhole location. Latitude and longitude for each drillhole at a project site shall be reported for heat exchange projects requiring approval under s. NR 812.09 (4). Heat exchange drillhole construction reports shall be spaced across the project site as practicable as possible, or should be reflective of geologic variation that may occur across the site. A well construction report shall be submitted for any well deepening. A water well or heat exchange drillhole is completed when all operations that require the use of drilling, driving or annular space sealing equipment have been completed. A well construction report is not required for well screen replacement if the screen is set to a depth not exceeding 5 feet above or below the original screen depth setting. A well construction report is also not required for blasting or hydrofracturing when done within 30 days after original completion of the well construction. Such work shall be reported on the original well construction report or on a copy of the original report. An accurate and complete well construction report shall be submitted on a form prescribed by the department to:
NR 812.22(7)(a)1. 1. Department of natural resources; and
