Special Application Requirements

Initial Demonstration of Capability (IDC) & Method Detection Limit (MDL) Results

The table below summarizes the tests and categories for which laboratories are required to submit either MDL, IDC or both IDC and MDL data along with their application. submit. Specific information concerning the requirements regarding minimum limits of detection and Wisconsin's low-level reporting rule can be found in the Program Information and Requirements Booklet (PUBL TS 007 98).


Test Category Analytes Required Data
4 Hexane Extractable Materials MDL and IPR as specified in EPA Method 1664
2, 3, 5 or 6 Anions by Ion Chromatography MDLs for each analyte under application
13 Polycyclic Aromatic Hydrocarbons; Aldehydes and Ketones; Carbamate and Urea-Substituted Pesticides; Explosive Residues MDLs and IDCs for each method and analyte under application
14 Acid Herbicides; Organophosphorus Pesticides; Nitrogen, Triazine and Metabolite Pesticides MDLs and IDCs for each method and analyte under application
15 Gasoline Range Organics (GRO); Diesel Range Organics (DRO); Petroleum Volatile Organics (PVOC) MDLs and IDCs by the Wisconsin methods are required in both soil and water matrices.
16 Organochlorine Pesticides; Polychlorinated Biphenyls MDLs and IDCs for each method and analyte under application
18 All analytes covered under the Safe Drinking Water test category MDLs are required for all inorganic and organic analytes. IDs are required only for the organic analytes
Per s. NR 149.07(1)(d), Wis. Adm. Code, the Department may request, on a case-by-case basis, any additional information necessary to demonstrate a laboratory's compliance with the requirements of this chapter.

Applying for Drinking Water (SDWA) Certification

Laboratories applying for Safe Drinking Water Testing are required to comply with all the requirements of EPA's Drinking Water Certification Manual, as well as meet the criteria listed below.

  • Submit acceptable PE samples from one of the approved water supply sample providers.
  • Laboratories applying for Drinking Water certification must submit Initial Demonstrations of Capability (precision and accuracy) for each organic analyte and method. The instructions for the IDCs are typically found in the methods.
  • Laboratories applying for Drinking Water certification must submit Method Detection Limit (MDL) studies for each analyte (organic and inorganic) and method.
  • Applying for Low Level Mercury Recognition

    A provision in the Laboratory Certification Administrative Code,.NR 149.12(2) Wis. Admin. Code, authorizes WDNR to recognize emerging analytical technologies when laboratories request recognition and those technologies meet the needs of the Department. For more information on what is required see the information posted at http://www.dnr.state.wi.us/org/es/science/lc/mercury/.

    Applying for Petroleum Hydrocarbons Certification or Registration

    Wisconsin has a unique Leaking Underground Storage Tank (LUST) program which is different from many other states' programs. Primarily, the Department of Natural Resources has developed its own sampling and analytical methods for gasoline range organics (GRO) [WI-PUBL- SW-140] and diesel range organics (DRO) [WI-PUBL-SW-141]. Laboratories applying for Wisconsin certification are required to use the latest version of these methods which are available on the REMEDIATION AND REDEVELOPMENT PROGRAM WEB PAGE AT http://www.dnr.state.wi.us/org/aw/rr/archives/pubs/SW140.pdf . Alternatively, they are available for a shipping and handling fee from the Bureau of Remediation and Redevelopment, 101 S. Webster St., Madison, WI 53707, phone (608) 261-264-6020.

    In addition to meeting all usual the requirements for completing the application, laboratories that are applying for certification for petroleum hydrocarbons must include the following information with the application:

    Listed below are common problems that the Department finds with Petroleum Hydrocarbon Analyses. Please make sure that your lab corrects these problems BEFORE you apply.
