“…Several chemical processors conducted operations in this area from 1947 to 1966, including the pesticide formulator United Heckathorn. Chemical releases from processing and equipment washing caused DDT and dieldrin contamination in the embankment soil, sediment, and water of Lauritzen Channel [1]. The U.S. Environmental Protection Agency (U.S. EPA) added the United Heckathorn site to its National Priority List of Federal Superfund sites in March 1990, and a site history and description of embankment soil remedial actions can be found in Weston et al [2].…”

Pesticide formulators formerly operating at Lauritzen Channel, a portion of San Francisco Bay near Richmond (CA, USA), caused contamination of sediment with dichlorodiphenyltrichloroethane (DDT). The present study evaluated the distribution of residual DDT in channel sediment six years following extensive remedial dredging. High DDT concentrations (up to 252 mg/ kg) were found in Young Bay Mud sampled across the channel. Particle analyses showed most of the contamination is contained in the clay/silt sediment fraction, and desorption tests showed that availability is greater for DDT metabolites than parent DDT. The present study examined the feasibility of using activated carbon amendment to sequester DDT from sediment, including an evaluation of reactivated carbon as a less costly alternative to virgin activated carbons. Treatment success of activated carbon amendment to sediment collected from Lauritzen Channel was measured by reductions in aqueous equilibrium concentrations and uptake in semipermeable membrane devices (SPMDs). Four different activated carbons were tested and, after one month of treatment with 3.2 weight % carbon, DDT aqueous equilibrium concentrations were reduced up to 83% and SPMD uptake was reduced up to 91%. Reactivated carbon was comparable with virgin carbons in all tests. Reduction in SPMD uptake of DDT by treatment with 3.2% reactivated carbon increased to 99% after 26 months of treatment. The effectiveness of activated carbon was dependent on the type, size, dose, and contact time. The results show the potential usefulness of activated carbon amendment as a follow-up remedial technology for management of residuals after dredging contaminated sediment.

“…The Feasibility Study (Lincoff et al 1994) and the ROD reviewed federal and state environmental laws that contained Applicable or Relevant and Appropriate Requirements (ARARs) for the remediai actions. EPA marine chronic and human health water quality criteria (WQC) were identified as ARARs for surface water.…”

“…CDFS are used to contain approximately 30% of the dredge material produced by the U.S. Army Corps of Engineers (U.S. ACE) Navigation Program (Lincoff et al 1994 appropriate. Although contaminants are not destroyed (i.e., toxicity is not decreased) and their volume is not reduced, this process option prevents the migration of contaminants by isolating the waste within an impervious landfill.…”
