The mission of the ABL (part of DFG's Water Pollution Control Laboratory)  is to support
the use of biology in California's water quality management and assessment programs.

The ABL has four main programmatic units:

•   Laboratory Program

  The ABL's laboratories in Rancho Cordova and Chico provide extensive expertise in freshwater invertebrate taxonomy.

•   Data Collection

  Field sampling protocols include targeted riffle and multiple habitat sampling of macroinvertebrates, fish and algae as well as associated physical habitat and chemical monitoring.

•   Research Program

  The ABL has active research programs throughout California. Current research efforts are focused on developing IBIs for different regions, developing objective reference condition selection methods and establishing quantitative tolerance values.

•   Bioassessment Enforcement

  Macroinvertebrate data often provide a critical component to enforcement of the states water regulations. The ABL provides support for enforcement branches of OSPR and DFG.
