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 NoteNote: 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.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 NoteNote: 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.t.t. The locations of alternate well sites for the proposed well and other information such as test pumping or modeling as requested by the department in order to conduct a review under ch. 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)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. Sampling shall be sufficient to adequately determine the water quality characteristics. The report shall summarize information on hydrological data, such as safe yield, maximum and minimum water levels or flows, the quality of raw water with special emphasis on results of testing programs, fluctuation in water quality, including seasonal variations and effects, the presence of befouling organisms, and existing and future potential sources of contamination.

NR 811.09(4)(j)3.3. ‘Water treatment or chemical addition processes.’ The engineering report shall include a summary establishing the adequacy of the proposed processes for the treatment of the specific water under consideration. The report shall include any data from pilot or full scale plant studies and describe the method of disposal of any wastes and any possible effects on the environment.

NR 811.09(4)(j)4.4. ‘Pumping facilities.’ The engineering report shall include a description of the area to be served and the basis for design, including maximum and minimum discharge heads and flows, pump operational controls, and provisions for emergency operation.

NR 811.09(4)(j)5.5. ‘Water storage facilities.’ The engineering report shall include a description of the high to low static pressure range which the proposed facility will provide for existing and future service areas and the volume of domestic and fire storage required within the design period. The report shall explain how the proposed and existing facilities will meet these requirements. The report shall also relate the compatibility of the proposed facilities with existing facilities and any changes that will have to be made to the existing facilities.

NR 811.10NR 811.10 Owner approval requirement. If an engineer or other agent submitting plans to the department is not an employee or otherwise retained by the owner of the water system, written acceptance of the final plans by the owner is required. A copy of the owner approval letter shall be included along with the submission of the plans to the department.

NR 811.10 NoteNote: As an example, if an engineer is retained by a developer to design water main extensions which will be connected to a municipal system and eventually be owned by the municipality, the plans must be accepted in writing by the municipality prior to the submission of plans to the department.
