Section NR 716.03 - Definitions 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).Wis. Admin. Code Department of Natural Resources NR 716.03
