Tracking Toxics in the Lower Columbia River
USGS scientists partnered with the Lower Columbia Estuary Partnership (LCEP) to assess toxic contaminant levels at 10 sites within the Lower Columbia River. Our strategy is to compare current toxic contaminant levels to the results collected previously at these sites to identify temporal changes.
Recharge to the Columbia River Basalt Groundwater System

Multiscale comparison of hyperspectral reflectance from periphyton in three Oregon rivers used for municipal supply
In this study, USGS scientists from multiple centers used advanced hyperspectral imaging techniques to advance monitoring of attached benthic algae (periphyton) in Cascade Range rivers used for municipal water supply. Periphyton are naturally occurring, but excess growth can harm ecosystems and degrade raw and treated drinking water quality. In these rivers, periphyton contain cyanobacteria that...
Cloud Water Interception in Hawai‘i
Because of the extreme climate gradients in Hawai‘i, relatively small shifts in atmospheric circulation can cause major changes in rainfall, cloud cover, and humidity. Because it has been shown that cloud water forms an important input at specific sites, we need to understand how these inputs vary across the landscape, or how interactions with plant communities alter direct inputs. Such changes...
