The primary function of the Quality Assurance Program is to ensure the accuracy of data collected through the District’s Air Monitoring and meteorological Networks and from the District Laboratory. The monitoring network provides the data required to determine attainment status of both National and State ambient air quality standards. Data collected in other monitoring projects, such as Dioxin and PM2.5 speciation, also need to be validated through Quality Assurance audits.

The Laboratory provides analytical services to the Technical, Permits and Enforcement Divisions. Data generated by laboratory instrumentation and analytical methods require quality assurance assessment to meet EPA validation requirements. The Quality Assurance Program is responsible for audits and data evaluation of the H2S and SO2 ground level monitors (GLM) and operation of H2S and SO2 mobile sampling units for odor complaint investigation and episodic sampling.
