FIRST MONITORED NATURAL RECOVERY REPORT, DATA COLLECTIONS 2013-2016 PALOS VERDES SHELF, OPERABLE UNIT 5 OF THE MONTROSE CHEMICAL CORPORATION SUPERFUND SITE, LOS ANGELES COUNTY, CALIFORNIA
EPA Region 9, 162 pp, 2018

A sampling and analysis program was conducted at Palos Verdes Shelf (PV Shelf) in support of monitored natural recovery (MNR) of DDT and PCBs that migrated to the PV Shelf from industrial discharges in the 1960s and formed a bed of "effluent affected" sediment. Although conditions at PV Shelf appear to be improving, significant areas of sediment remain highly contaminated, and DDT and PCBs concentrations in samples of water and fish exceeded cleanup goals. EPA will continue the MNR sampling program to evaluate the effectiveness of MNR and to develop final remediation alternatives for PV Shelf cleanup. https://semspub.epa.gov/work/09/100008054.pdf
