Auditing for WV DEP Water and Waste Management involves municipal, industrial, and commercial wastewater treatment facilities. Expert knowledge of various methods under the Clean Water Act 40CFR136 and the WV regulations that govern them under WV47CSR32 is required. The enforced regulations establish practices for quality control, practices, methodology, data reporting, and record maintenance. The goal is for each facility's data to be accurate, reproducible, and verifiable.
