Copper speciation in highway stormwater runoff as related to bioavailability and toxicity to ESA-listed salmon

The objectives of this study were to 1) identify the effects of site location, storm hydrology, and water quality parameters on the concentration of dissolved copper (Cu2+diss) in Oregon highway runoff; 2) establish an analytical technique suitable for the determination of copper speciation in highway stormwater runoff; 3) compare analytically determined free ionic copper (Cu2+free) concentrations in highway stormwater runoff with modeled concentrations; and 4) develop a qualitative understanding of where and when copper toxicity has the most potential to be problematic for receiving waters, This archived document is maintained by the Oregon State Library as part of the Oregon Documents Depository Program.
