Source Control and Sediment Cleanup in Portland Harbor

Integral Consulting has contracted CRETE to provide engineering design, allocation, and forensic expertise for a Portland Harbor Superfund Site PLP. Source control activities will include restoration of a steep riverbank with erodible PCB-containing soil and evaluations/adjustments to the stormwater management system. CRETE staff have conducted several source control evaluations for this PRP and have a long history with the Portland Harbor Superfund process. Allocation support includes historical research and forensic investigations, as well as consideration of upstream-sourced impacts to nearshore river sediment.
