Summary

For nearly two and a half decades following World War II, production wastes from the world’s largest manufacturer of technical DDT were discharged into sewers of Los Angeles County. Following treatment, the wastes were released via a submarine outfall system to nearshore coastal waters where a portion accumulated in shallow sediments of the Palos Verdes Shelf (PVS). An investigation of the pore-water geochemistry of DDT-related compounds (DDX) was undertaken in an effort to understand factors controlling the rate of reductive dechlorination (RDC) of the major DDT degradate, 4,4’-DDE. Equilibrium matrix-solid phase microextraction (matrix-SPMEeq) combined with automated thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS) [...]

Purpose

Data were collected to investigate the porewater geochemistry of DDT-related compounds in an effort to understand factors controlling the rate of reductive dechlorination of 4,4'-DDE in sediments of the Palos Verdes Shelf (CA) in support of the U.S. Environmental Protection Agency's Palos Verdes Site Remediation Plan.
