Chapter NR 141 - Groundwater Monitoring Well Requirements
Section NR 141.27 - Driven point wells
Current through August 26, 2024
Driven point wells with galvanized steel drive pipes and contaminant compatible well screens may be used as permanent groundwater monitoring wells if prior department approval is obtained. Written documentation shall be supplied to the department prior to installation indicating:
(1) That the well is to be used only for water table elevation measurements or to monitor for parameters for which the well casing and screen material will not interfere with the analytical results;
(2) That the well will not provide a conduit for contaminants to enter the groundwater; and
(3) That information on subsurface stratigraphy is not needed. In situations where subsurface geologic information is needed, a separate borehole shall be constructed to collect the required data.
