Note: The limit of quantitation is established as defined under s. NR 149.48(3).
Note: Pursuant to s. 299.11(4) (c), Stats., sub. (13) (Note) is shown as amended eff. 6-29-21 by CR 17-046. Prior to 6-29-21 it reads:
Note: The limit of quantitation is 10/3 or 3.333 times the limit of detection.
(14) "Monitoring" means all procedures used to collect data on groundwater, surface water or soils. (14m) "Natural attenuation'' means the reduction in the concentration and mass of a substance and its breakdown products in groundwater, due to naturally occurring physical, chemical, and biological processes without human intervention or enhancement. These processes include, but are not limited to, dispersion, diffusion, sorption and retardation, and degradation processes such as biodegradation, abiotic degradation and radioactive decay.(15) "Point of standards application" means the specific location, depth or distance from a facility, activity or practice at which the concentration of a substance in groundwater is measured for purposes of determining whether a preventive action limit or an enforcement standard has been attained or exceeded.(16) "Precision" means the closeness of repeated measurements of the same parameter within a sample.(17) "Preventive action limit" means a numerical value expressing the concentration of a substance in groundwater which is adopted under s. 160.15, Stats., and s. NR 140.10, 140.12 or 140.20.(18) "Property boundary" means the boundary of the total contiguous parcel of land owned or leased by a common owner or lessor, regardless of whether public or private roads run through the parcel.(19) "Registered laboratory" means a laboratory which is registered under s. 299.11(8), Stats., or receives reciprocal recognition under s. 299.11(5), Stats.(20) "Regulatory agency" means the department of agriculture, trade and consumer protection, the department of safety and professional services, the department of transportation, the department of natural resources and other state agencies which regulate activities, facilities or practices which are related to substances which have been detected in or have reasonable probability of entering the groundwater resources of the state. (20h) "Remedial action" means a response which is taken to achieve compliance with groundwater quality standards established under this chapter. This term includes, but is not limited to, actions designed to prevent or minimize the further discharge or release of substances to groundwater and actions designed to renovate or restore groundwater quality.(20k) "Remedial material" means any solid, liquid, semi-solid or gaseous material, either naturally occurring or manmade, in its original form or as a metabolite or degradation product, or naturally occurring non-pathogenic biological organisms which have not undergone human induced genetic alteration, which enhances the restoration of soil or groundwater quality, or both.(20m) "Response" means any action taken to respond to an attainment or exceedance of a preventive action limit or enforcement standard as required by s. NR 140.24 or 140.26. Note: A response may include a remedial action.
