Lab & Source Test
Learn about how the Air District’s Lab & Source Test sections measure and analyze samples from the monitoring network, field samples, and regulated facility emissions.
Laboratory
The Laboratory Section (Lab) provides technical services and support to Air District staff by analyzing a wide variety of samples for potential enforcement action. The Lab is also capable of analyzing a variety of samples during and after episodic events. The Lab occasionally participates in special projects in support of a wide variety of agencies and institutions to monitor air quality regionally and locally.
The Lab also performs analyses in support of USEPA, state and Air District programs to monitor air quality in the Bay Area and is audited by them, and other agencies in order to maintain exemplary quality control standards. Public tours of the Lab are available upon request.
Source Test
The Source Test Section provides the expertise and equipment to determine the type and quantity of pollutants emitted from sources by sampling effluent streams. Quantification of pollutant emissions allows the Air District to determine if a source is in compliance with environmental regulations. Compliance is accomplished in a variety of ways; including, but not limited to, conducting analytical source tests, review and determination of acceptability of third-party source tests, conducting performance audits on Continuous Emissions Monitoring (CEM) and Predictive Emissions Monitoring (PEM) systems, and performing compliance audits at gasoline dispensing facilities (GDFs).
