NR 510.05 Note Note: NR 508.10 was repealed eff. 7-1-96.
NR 510.05(3) (3)Field direction. A professional geologist or qualified technician who is directly supervised by a professional geologist shall observe and direct the drilling of all borings and the installation, development and abandonment of all wells. The professional geologist or qualified technician who is directly supervised by a professional geologist shall also visually describe and classify all geologic samples.
NR 510.05(4) (4)Laboratory and field analyses. Laboratory and field analyses conducted to identify the specific geologic and hydrogeologic conditions at the proposed landfill's location shall:
NR 510.05(4)(a) (a) Include testing a minimum of one representative sample from each major soil unit encountered. Each representative sample shall be analyzed for grain-size distribution using mechanical and hydrometer methods and Atterberg limits as appropriate for the particular type of material and be classified according to the unified soil classification system.
NR 510.05 Note Note: A major soil unit is defined in s. NR 500.03 (138).
NR 510.05(4)(b) (b) All available groundwater or surface water quality data which have been obtained from sampling at the proposed landfill's location shall be submitted in the report. Any environmental monitoring data included in the report shall be submitted on department forms or on diskette.
NR 510.05 Note Note: The department recommends that any site-specific geotechnical investigation for an initial site report or a pre-feasibility report not be initiated prior to receiving the department's initial site inspection evaluation of the proposed property. The department also recommends that any follow up studies and evaluations requested by the department in its initial site inspection evaluation to determine compliance with the locational criteria and performance standards of s. NR 504.04 be completed to the degree possible prior to submitting an initial site report or a pre-feasibility report. For example: If the department requests an archeological investigation or an endangered resources study to be completed, such information should be included in the initial site report or a pre-feasibility report. However, if the proposed landfill will have an impact on a wetland, the practicable alternative analysis required by ch. NR 103 should be submitted with the initial site report or pre-feasibility report, but the identification of the wetland functional values and the significance of the potential adverse impact upon those functional values may be submitted with either the initial site report, the pre-feasibility report or the feasibility report.

The date the measurements were taken shall be specified in the key.
NR 510.06(3) (3)Water table map. A water table contour map shall be submitted when 4 or more observation wells have been installed to define the site-specific hydrogeology. The map shall be based on stabilized water levels recorded on the same day from the observation wells installed at the proposed landfill's location and show the wells and the measured water level at each well. For a proposed contiguous, horizontal or vertical expansion of an existing landfill, the water table contour map shall include the observation wells and measured water table elevations at each well for the existing landfill. The topographic map shall be used as a base map. If more than one set of water levels has been taken, the water table contours shall be based on the set of data which indicates the highest water table. Any observed variations in flow direction shall be discussed in the narrative of the report. Inferred contours made beyond the extent of the well field shall be shown with dashed lines.
