Analytical requirements for volatile organic contaminants

Analytical requirements for volatile organic contaminants. (1) Detection limits. For the purposes of this section, detection is defined as >0.0005 mg/l, except for vinyl chloride for which detection is defined as >0.0002 mg/L. (2) Analytical methods. Analysis for the volatile organic contaminants listed in s. NR 809.24 shall be conducted using the methods prescribed in Table E. (3) Sample collection. Samples shall be collected using containers, preservatives and holding times specified in s. NR 809.203 (4) Table D. In all cases, samples should be analyzed as soon after collection as possible. (4) Laboratory certification. Analyses under this section shall only be conducted by laboratories that have received certification under ch. NR 149 or have been approved by EPA. (5) Laboratory evaluation. Each certified laboratory shall determine the method detection limit (MDL) at which it is capable of detecting VOCs as defined in federal law under 40 CFR, Part 136 , Appendix B. The maximum acceptable MDL is 0.0005 mg/L for all VOCs except vinyl chloride, which is 0.0002 mg/L.
