NR 110.09(8)(b)(b) Hydrogeological investigation.
NR 110.09(8)(b)1.1. A hydrogeological investigation shall be included as part of the facilities plan. The analysis of the hydrogeological information shall be done by a hydrogeologist, or other qualified person. The investigation shall include both regional and site-specific hydrogeological information.
NR 110.09 NoteNote: The skills and knowledge required of a hydrogeologist making submittals under this chapter include: the ability to apply hydrogeologic principles and practices to the siting, design and operation of land disposal systems; knowledge of contaminants associated with land disposal of wastewater, their transport mechanisms and fate in the environment; familiarity standards; and proficiency in the design of groundwater monitoring systems for defining the physical and chemical characteristics of groundwater flow. A soil scientist or other environmental scientist who can demonstrate the above skills and knowledge, as reflected in submittals made under this chapter, shall be deemed a “qualified person”.
NR 110.09(8)(b)2.2. The following site-specific groundwater information may be required as part of the facilities plan for land disposal facilities:
NR 110.09(8)(b)2.a.a. Depth to highest anticipated groundwater elevation.
NR 110.09(8)(b)2.b.b. Groundwater flow directions and rates of flow.
NR 110.09(8)(b)2.c.c. Vertical and horizontal gradients.
NR 110.09(8)(b)2.d.d. Groundwater quality.
NR 110.09(8)(b)2.e.e. Presence of groundwater divides and barriers.
NR 110.09(8)(b)2.f.f. Presence and extent of perched groundwater.
NR 110.09(8)(b)2.g.g. Mounding calculations.
NR 110.09(8)(c)(c) Soil investigation. The soil evaluation may be performed in conjunction with the hydrogeological evaluation; however, each evaluation shall be performed by a person who is qualified to perform the evaluation. The following site-specific soil information shall be submitted as a part of the facilities plan for land disposal systems;
NR 110.09(8)(c)1.1. Soil borings and sampling performed in accordance with ss. NR 110.24 (3) (d) and 110.24 (4) (d), and test pit analyses. The one boring per acre minimum of s. NR 110.24 (3) (d) 4. does not apply to spray irrigation, ridge and furrow, or overland flow systems. A soil analysis may be required on a case-by-case basis for land disposal systems. The USDA soil classification system shall be used for spray irrigation systems, ridge and furrow, and overland flow systems.
NR 110.09(8)(c)2.2. Soil descriptions, including soil profile, stratification, slope, soil moisture content, continuity, structure, texture, relative density and depth to groundwater and bedrock.
NR 110.09(8)(c)3.3. Soil analyses shall be performed on the zone of soil which will provide treatment of the wastewater. The department may require that the analyses include any or all of the following: grain size analyses, hydrometer analyses, field and laboratory horizontal and vertical permeabilities, Atterberg limits, soil pH, cation exchange capacity, bulk density and relative density, porosity, soil nutrient content, and organic matter content.
NR 110.09(8)(c)4.4. In-field infiltration rates (measured at the proposed elevation of application).
NR 110.09(8)(c)5.5. A description of the soil testing methods used.
NR 110.09(8)(c)6.6. Depth to bedrock.
NR 110.09(8)(c)7.7. Type and nature of bedrock.
