Wisconsin Administrative Code › Department of Natural Resources › NR 700-799 - Environmental Protection - Investigation and Remediation of Environmental Contamination › Chapter NR 716 - Site Investigations › Section NR 716.03 - Definitions

Current through June 24, 2024
In this chapter:
(1) "Batch of samples" means a group of
				samples collected during one discrete sampling event and stored and transported
				in a single shipping container, regardless of the number of samples in the
				group.
(2) "Equipment blank" means
				a sample of water which, prior to use, is known to be free of contaminants, and
				which is processed through the sampling equipment in the field in the same
				manner as the actual water sample to determine if field procedures introduce
				contaminants into the samples. This is also known as a "rinse blank" or a
				"field equipment blank."
(3)
				"Immunoassay" means a test for the presence or concentration of a substance
				that relies on the reaction of one or more antibodies with the
				substance.
(4) "Investigative
				waste" means all solid and liquid wastes and contaminated environmental media
				resulting from activities conducted during a site investigation, immediate
				action, interim action, remedial action, or a monitoring or sampling event at a
				site or facility. Investigative wastes include soil from drill cuttings;
				drilling fluids; contaminated water from construction, purging, development and
				sampling of monitoring wells; and wash waters used during sampling or
				decontamination activities.
(6)
				"Piezometer" has the meaning specified in s. NR 141.05 (30).
Note:
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."
(7) "Potentiometric
				surface" has the meaning specified in s. NR 141.05 (31).
Note:
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."
(8) "Replicate
				sample" has the meaning specified in s. NR 149.03 (70).
Note:
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."
(8m) "Responsible parties" means, in this
				chapter, those parties defined under s. NR 700.03 (51) as well as those parties
				identified under s. NR 716.02 (1).
(9) "Temperature blank" has the meaning
				specified in s. NR 149.03 (78).
Note:
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."
(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.
(11) "Water table observation well" has the
				meaning specified in s. NR 141.05 (46).
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."
