The work will start in front of the now-shuttered Diamond Shamrock plant in Newark, whose products included Agent Orange, the defoliant used in the Vietnam War.
A second phase will remove additional sediment from areas near the plant. Together, about 200,000 cubic yards of the most-contaminated mud are to be removed.
Officials say the $80 million project will be paid for by Occidental Chemical and Tierra Solutions and take about two-and-a-half years to complete.
