Wisconsin Administrative Code › Department of Natural Resources › NR 100-199 - Environmental Protection General › Chapter NR 149 - Laboratory Accreditation › Subchapter III - Program Structure › Section NR 149.13 - Fields of accreditation: certification and registration

Current through June 24, 2024
(1) GENERAL. The
				  department shall certify and register laboratories by specific fields of
				  accreditation. Accreditation shall be by certification under s.
				  299.11(7),
				  Stats., or registration under s.
				  299.11(8),
				  Stats. Fields of accreditation consist of 3 tiers describing the analytical
				  capability of laboratories.
(2)
				  TIER 1 - MATRIX. The first tier of accreditation is comprised of aqueous,
				  non-aqueous, and drinking water matrices.
Note:
Biosolids and sludges are a non-aqueous
					 matrix for accreditation purposes.
(3) TIER 2 - TECHNOLOGY OR METHOD.
(ag) The second tier of accreditation is
				  comprised of analytical technologies for the aqueous and non-aqueous matrices
				  or methods for the drinking water matrix.
(ar) The department may certify or register
				  laboratories that analyze aqueous and non-aqueous matrices for the analytical
				  technologies contained in this section, Table 1.
(b) The department shall include any
				  associated sample preparation techniques, such as digestions, distillations,
				  extractions, cleanups, concentrations, and dilutions as part of the
				  certification or registration for a given field of accreditation.
(c) Laboratories may employ multiple methods
				  of analysis for a given analytical technology under the same field of
				  accreditation.

				  technology is only available for the non-aqueous matrix - Tier 1.
3. The department may offer accreditation in
				  other analytical technologies if the technology is approved by the EPA or is
				  approved by the department as an emerging technology.
(d) The department may certify laboratories
				  analyzing drinking water samples using methods promulgated or approved by the
				  EPA under 40 CFR Part 141.
