This data release contains the analytical results of three contaminant classes in water using two types of passive sampling devices. Samples were collected at eight sites in the lower Columbia River and two sites in the lower Willamette River in Oregon and Washington. A Polar Organic Compound Integrating Sampler (POCIS) and a Solid-Phase Adsorption Toxin Tracker (SPATT) sampler were deployed at the ten sites in three separate seasons in 2023 to capture a range of environmental conditions. The POCIS samplers were used to detect the presence of both per- and polyfluoroalkyl substances (PFAS, n=75) and waste indicator compounds (WI, n=39). The SPATT samplers were used to detect four cyanotoxins present in the water: microcystins/nodularins (ADDA), cylindrospermopsins, anatoxins, and saxitoxins. Both sampler types were deployed over various lengths of time to concentrate chemicals and toxins and allow for the detection of chemical and toxin concentrations at low levels.
