Portland Harbor Superfund Site

From 2004-2014, CMA conducted an extensive Trident and UltraSeep assessment to identify and quantify groundwater discharge zones and rates in support of a Remedial Investigation at the Portland Harbor Superfund Site, Portland, Oregon. An extensive Trident sensor survey was successfully executed to identify potential discharge zones, encompassing over 400 stations. Trident porewater samples were subsequently collected at ~50 potential discharge zones.
