SCCWRP-developed sediment bioaccumulation model being tested in L.A./Long Beach Harbors

SCCWRP and the Harbor Technical Work Group, which is working to address a TMDL (total maximum daily load) in Los Angeles and Long Beach Harbors, launched an effort in November to evaluate the accuracy of a new statewide sediment quality tool developed by SCCWRP.

Project participants are using TMDL data collected from the Harbors area to assess the effectiveness of a bioaccumulation model for the State Water Board’s Sediment Quality Objectives program.

The bioaccumulation model, which quantifies health risks to humans from seafood contamination, is intended to help coastal managers achieve California’s goals for sediment quality in enclosed bays and estuaries statewide.
