What We Do

The Chicago Regional Laboratory provides scientific expertise, training and environmental data of known and appropriate quality. Our contributions advance EPA’s mission of protecting human health and the environment. Our work supports environmental decision-making by the Region, by programs in Agency headquarters, and by organizations in the public and private sectors. This Center of Applied Science maintains and expands its capabilities by developing methods for emerging compounds of concern and improving the performance of existing analytical methods. We are committed to improving the quality of our data and the efficiency of our processes. We continually expand our knowledge and capabilities to meet new environmental challenges. We meet our customers’ needs through timely, complete, and scientifically sound responses.

We are accredited to the ISO-IEC 17025-2005 Standard.
