Use a distinguishing symbol, such as a dashed line or question mark, to depict inferred or questionable data.
For water table maps and potentiometric surface maps, depict water level elevations measured on the same day, indicate the date of measurement on the map, and indicate apparent flow direction. For potentiometric surface maps, additionally depict measurements taken from piezometers with similar screen lengths that intersect the same geologic zone and depth, and indicate any vertical gradients as well as the location and type of any confining layers.
For isoconcentration maps, depict hazardous substance concentrations and indicate the hazardous substance, the environmental medium, the date measured and the unit of measurement.
Cross sections shall include a reduced inset diagram of the site layout map indicating the location of the cross-section transect, and shall indicate the dates of measurements, stratigraphy, screened intervals of monitoring wells and water table surface.
Have a table number, title and an explanation of any footnotes marked in the body of the table.
Include units of measurement when displaying measured data. When an environmental standard exists for the contaminant, the unit of measurement shall be the same as that used by the department to express the environmental standard.
Indicate measurement or sample collection date when displaying measured data or data derived from sampling.
Indicate which results equal or exceed environmental standards when displaying analytical results of tests on environmental media for which standards exist.
Photographs shall be in color, of sufficient size to clearly represent the purpose of the photograph, and shall be accompanied by the date, orientation and topic.
(i) Well and borehole documentation.
All of the following department forms, shall be used, where applicable to the site or facility:

(j) Legal descriptions and parcel identification numbers.
All of the following information shall be included for each property within or partially within the contaminated site boundaries:

A copy of the certified survey map or the relevant portion of the recorded plat map for those properties where the legal description in the most recent deed refers to a certified survey map or a recorded plat map.
The parcel identification number for each property if the county in which the property is located uses parcel identification numbers.
(k) Geographic position.
All geographic position data shall be obtained and submitted to the department in accordance with the following requirements:
For properties that are not more than 200 feet wide or long, a single point geographic position shall be obtained at least 40 feet within the boundaries of the property, or as close to the center of the property as possible if the property is less than 80 feet wide or long. For properties that are more than 200 feet wide or long, coordinates describing the approximate location of the property's boundaries, forming a polygon, shall be obtained.
2. `Coordinate system.'
Geographic position data shall be originally collected in Wisconsin Transverse Mercator `91 or projected onto Wisconsin Transverse Mercator `91.

When warranted by the complexity of the site or facility or the severity of the actual or potential environmental or public health impacts which may be caused by the contamination, the department may impose additional site investigation requirements upon responsible parties beyond those specifically described in this chapter. The department shall communicate any additional investigation requirements to the responsible parties in writing and shall explain why the additional requirements are needed.
The department may require that treatability studies be conducted as part of the site investigation, where appropriate for the purpose of demonstrating that an interim action or remedial option will meet the remedy selection criteria in ch. NR 708
When a site investigation conducted under this chapter indicates that an immediate, interim or remedial action is necessary, the responsible parties shall identify, evaluate and select an immediate or interim action in accordance with ch. NR 708
or a remedial action in accordance with ch. NR 722
When a site investigation conducted under this chapter indicates that, based on the criteria in s. NR 726.05 (1)
, no further action is necessary to protect public health, safety or welfare or the environment, the responsible parties may request that the department close the case in accordance with ch. NR 726
