| Description: |
The State of California is developing Sediment Quality Objectives
(SQOs) for use as screening criteria for contaminated sediment evaluation (for more information, see:
http://www.swrcb.ca.gov/bptcp/sediment.html). The project has utilized sediment chemistry, bioassay, fish tissue bioaccumulation, and benthic infaunal data from bays and estuaries of the state. The multi-year program goal is to establish methods for evaluating the relationship between sediment quality and biological effects. Exa was responsible for developing and populating the database, coordinating with a multi-disciplinary technical project team, developing programs to assist with analyses, and delivering both a User Guide and Technical Reference Manual for the database. |
