California recently adopted an innovative framework for assessing sediment quality impacts to the benthic community based upon multiple lines of evidence. The seven articles in the series address one aspect of a multi-phase project to define sediment quality objectives, including a new sediment quality guideline (SQG) index.Steve Bay, Guest Editor of the special series “California Sediment Quality Objectives,” describes how the series articles define sediment quality objectives for California that will be used to protect fish, wildlife, benthic invertebrates, and even humans. Access the series in the October 2012 issue of IEAM.

About the Guest

SteveBaySteve Bay is a Principal Scientist with the Southern California Coastal Water Research Project (SCCWRP), where he conducts research into the linkage between chemical contamination and biological effects. He frequently advises California and federal agencies on water and sediment quality issues and has helped coordinate several large-scale regional monitoring surveys of water quality in southern California. Steve’s current research includes developing sediment quality assessment frameworks for the California Water Board and investigating the impacts of contaminants of emerging concern on aquatic organisms.
