NR 812.10(8) (8)Noncomplying wells. When a water well or heat exchange driller or well constructor has constructed a water well or heat exchange drillhole not initially located or constructed in compliance with this chapter, the water well or heat exchange driller or well constructor shall pay all costs for bringing the well or heat exchange drillhole into compliance with this chapter, including the costs of filling and sealing the well, if necessary, other than those costs that would have been charged for an initial complying well construction.
NR 812.10(9) (9)Problem wells. The well driller or well constructor shall return to the well site to attempt to correct problems when a potable well produces bacteriologically unsafe water; when a well produces sandy or turbid water; or when failure of the well occurs due to a caving or sloughing formation. The well driller or well constructor shall return within 90 days after the well is completed or 30 days after the well is placed in service, whichever is longer. If noncomplying construction was not the cause of the problem, a fee may be charged by the well driller or well constructor for corrective work.
NR 812.10(10) (10)Notification of contaminated wells. Well drillers and well constructors shall notify the well owner if the well driller or well constructor becomes aware that the water from the well contains contaminates in excess for the primary drinking water standards in ch. NR 809.
NR 812.10(11) (11)Completion of the well. In accordance with all requirements of s. NR 812.22 (6), the water well driller or his or her agent or the well constructor shall collect a water sample or samples, using his or her test pump, the well owner's pump, air-lift equipment or bailer, from any new or newly reconstructed, rehabilitated, redeveloped or reconditioned potable well, including driven point wells, no later than 30 days following completion of the well or work on the well. Each water sample shall be analyzed for coliform bacteria, nitrate and any water tests required when performing well construction or reconstruction in a special well casing depth area. Each water sample shall be analyzed for coliform bacteria by a laboratory certified by DATCP for 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 to the Wisconsin state laboratory of hygiene. Each 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. The water well driller or well constructor shall disinfect, flush and seal the well. The water well driller shall provide a copy of the laboratory test report(s) to the well owner no later than 10 days after receipt of the report(s) by the well driller. The water well driller or well constructor shall submit a well construction report to the well owner and to the department within 30 days following the date of completion of the well construction or reconstruction.
NR 812.10 Note Note: The well driller or agent is required to have the water sample analyzed for bacteria. However, in some areas of Wisconsin the useable aquifer is contaminated throughout its entire vertical extent, so it may not be possible to obtain a bacteriologically safe water sample.
NR 812.10(11m) (11m)Pressure testing of heat exchange loops. Vertical heat exchange loop piping shall be pressure tested with potable water or an approved fluid in the loop, according to manufacturer's specifications.
