NR 716.03 NoteNote: Section NR 141.05 (30) defines “piezometer” as “a groundwater monitoring well, sealed below the water table, installed for the specific purpose of determining either the elevation of the potentiometric surface or the physical, chemical, biological or radiological properties of groundwater at some point within the saturated zone or both.” NR 716.03 NoteNote: Section NR 141.05 (31) defines “potentiometric surface” to mean “an imaginary surface representing the total head of groundwater and is the level to which water will rise in a well.” NR 716.03 NoteNote: Section NR 149.03 (70) defines “replicate sample” to mean” 2 or more substantially equal aliquots analyzed independently for the same parameter.” This is also known as a “duplicate.” NR 716.03 NoteNote: Section NR 149.03 (78) defines “temperature blank” to mean “a sample container, of at least 40 ml. capacity, filled with water and transported with each shipment of collected samples to determine the temperature of other samples in the shipment on arrival at a laboratory.” NR 716.03(10)(10) “Trip blank” means a sample of reagent grade water which is used to determine possible contamination of samples from volatile organic chemicals while in transit to and from the laboratory. NR 716.03 NoteNote: Section NR 141.05 (46) defines “water table observation well” to mean “any groundwater monitoring well, in which the screen or open borehole intersects a water table, which is installed for the specific purpose of determining either the elevation of the water table or the physical, chemical, biological or radiological properties of groundwater at the water table or both.” NR 716.03 HistoryHistory: Cr.

NR 716.11(1)(1) Responsible parties shall conduct a field investigation as part of each site investigation required under this chapter, unless the department directs otherwise. NR 716.11(2)(2) The field investigation shall be conducted in accordance with a work plan approved or conditionally approved by the department, unless the department has directed the responsible parties to proceed with a field investigation without department review of the investigation work plan. NR 716.11(2g)(2g) The field investigation shall be initiated within 90 days of submittal of the work plan. NR 716.11(2r)(2r) In cases where the responsible party pays a fee for department review of the work plan, the field investigation shall be initiated within 60 days after department approval of the work plan. NR 716.11 NoteNote: The intent of this subsection is to be able to measure that progress is being made toward conducting a site investigation. Initiation may include preparatory measures to conducting the actual fieldwork.
NR 716.11(3)(3) The purposes of the field investigation shall be to: NR 716.11(3)(a)(a) Determine the nature, degree and extent, both areal and vertical, of the hazardous substances or environmental pollution in all affected media. NR 716.11(3)(b)(b) Provide sufficient information to permit evaluation of interim options pursuant to ch. NR 708, and remedial action options pursuant to ch. NR 722, and to permit a determination to be made regarding whether any of the interim or remedial action options require a treatability study or other pilot-scale study. NR 716.11(3)(c)(c) Provide sufficient information to determine the hydraulic conductivity of materials where contaminated groundwater is found. NR 716.11(3)(d)(d) Provide an estimate, along with all necessary supporting information, of the mass of contamination in the source area. This includes sites involving free product or where natural attenuation is considered for part of the remedy. NR 716.11 NoteNote: The intent of this paragraph is to address situations where a discrete area indicates a release of a hazardous substance. It is not intended for situations where there is no discrete source area, such as when there is area-wide contamination from aerial deposition, or widespread areas of fill such as foundry ash.
NR 716.11(4)(4) Responsible parties shall extend the field investigation beyond the property boundaries of the source area as necessary to fully define the extent of the contamination. If the responsible parties are unable to complete the required investigation beyond the source property because a property owner refuses access, the responsible parties shall notify the department within 30 days of the refusal, and shall document in writing the efforts undertaken to gain access when requested by the department.
