NR 811.09(4)(j)1.f. f. The potential contamination sources within 1/2 mile of the well location summarized in a table or list including distance and direction from the well site and also shown on a map surrounding the well site. The table or list shall include an assessment of the potential for the contamination sources to impact a well constructed on the site and shall include information obtained by checking the department’s database of contaminated properties, established in accordance with ss. 292.12 (3), 292.31 (1), and 292.57, Stats., and the department of safety and professional services Storage Tank Database.

NR 811.09 Note Note: The department’s database of contaminated properties, established in accordance with ss. 292.12 (3), 292.31 (1), and 292.57, Stats., can be found on the department’s Bureau for Remediation and Redevelopment internet web site. The Bureau for Remediation and Redevelopment Tracking System (BRRTS) is an on-line database that provides information on areas of known contaminated soil or groundwater and tracks the status of the cleanup actions. RR Sites Map is the program’s geographic information system that provides a map-based system of contaminated properties in Wisconsin. Information that appears on the RR program’s database and GIS applications can also be obtained by contacting the regional drinking water staff person responsible for the water system. The department can be contacted to obtain a copy of A Guide For Conducting Potential Contaminant Source Inventories For Wellhead Protection. The department of safety and professional services Storage Tank Database Information can be found on the department of safety and professional services internet web site.

NR 811.09(4)(j)1.h. h. The test or final well construction details, or both, including the descending order and depths of the specific geologic formations to be penetrated.

NR 811.09(4)(j)1.i. i. The proposed test or final well pumping capacity in gallons per minute, or both, as applicable.

NR 811.09(4)(j)1.j. j. The direction of groundwater flow in the specific geologic formation or formations from which water will be pumped or withdrawn.

NR 811.09(4)(j)1.k. k. The zone of influence of the proposed well consisting of the distance to one foot of aquifer drawdown at the anticipated final pumping rate when pumpage of the well is assumed to be continuous without recharge for 30 days. The zone of influence shall be calculated using the Theis Method with or without computer modeling unless another method is approved by the department. The aquifer transmissivity (T) and storage (S) coefficients used shall be provided.

NR 811.09(4)(j)1.L. L. The recharge area for the well. The recharge area shall be calculated using the Uniform Flow Equation or a computer generated groundwater model unless another method is approved by the department.

NR 811.09 Note Note: A copy of A Template For Preparing Wellhead Protection Plans For Municipal Wells, in which use of the Uniform Flow Equation is discussed, may be obtained from the department.

NR 811.09(4)(j)1.m. m. The results from any previous test wells including details of test well location and construction, water quality, pumping conditions including drawdown effects, if applicable, on other nearby wells or surface water bodies, geologic borings, and seismic, resistivity or other groundwater investigations.

NR 811.09(4)(j)1.n. n. The anticipated annual volume of water to be withdrawn and the compatibility with the existing water supply facilities.

NR 820 to justify the proposed well location if the well will be pumped at a rate equal to or greater than 70 gallons per minute and the department determines that the proposed well will be located within a groundwater protection area as defined in s. 281.34 (1) (am), Stats., or that operation of the well could result in significant adverse impacts to springs as defined in s. 281.34 (1) (f), Stats.

NR 811.09(4)(j)1.u. u. A summary evaluation of the site including advantages and disadvantages and the need for any possible water treatment.

NR 811.09(4)(j)2. 2. ‘Surface water sources.’ To assess the water available at the source, the engineering report shall include a survey and study of the source, including obtaining samples from a number of locations and depths in order to select the best intake site.
