The Office of Quality Assurance (OQA) certifies over 800 laboratories granting nearly 125,000 certifications each year. Certification is available in drinking water, wastewater, ambient water, soils, solid/hazardous waste, sludge and air for microbiological, toxicity, inorganic, organic, radon, radiochemical and biological properties. Most Department programs requiring the collection of data require certification. Certification is offered through both the state Environmental Laboratory Certification Program and the state run National Environmental Laboratory Accreditation Program. The OQA also administers the Department's Quality Assurance Program. It has the responsibility to ensure that environmental data is generated, compiled and reviewed using specific quality assurance / quality control (QA/QC) procedures. These procedures help to ensure that data is of documented quality and suitable for its intended use. These QA/QC requirements are based on Title 40 Code of Federal Regulations Parts 31 and 35 which lists both general and specific requirements for a state's environmental program and acceptable quality assurance for federally funded programs.
