The Columbia Slough is located south and parallel to the Columbia River in Portland, Oregon and consists of approximately 19 miles of predominantly urbanized waterway that drains approximately 32,700 acres of land with industrial, commercial, residential, and agricultural uses. Per- and polyfluoroalkyl substances (PFAS) are found in aqueous film forming foams (AFFF) used for firefighting, and soil and groundwater contamination by PFASs has been detected at Portland International Airport (PDX) and the adjacent Portland Air National Guard base (PANG). PFASs have also been detected in sediments from Columbia Slough, which receives stormwater runoff from both PDX and PANG. Fish tissue samples were collected from the...
This data release contains analytical results of organohalogenated compounds and mercury in lamprey and sediment that were collected from rivers in Oregon and along the Pacific northwest coast from 2017 to 2021. In 2017, 20 lamprey were collected off the Washington and Oregon coasts by the National Oceanic and Atmospheric Administration. These ocean-caught juvenile lamprey were parasitizing targeted fish and were bycatch. In 2019, larval lamprey were collected by the Confederated Tribes of Warm Springs of Oregon from 8 sites on the Warm Springs Reservation. Larval lamprey were collected by electroshocking depositional sediment areas. Collocated depositional sediment samples also were collected along with the larval...
