Content SummaryA well defined watershed was utilized to determines copper concentration, speciation and aquatic toxicity in stormwater runoff. Stormwater runoff samples were collected during 16 storm events from a copper roof, and simultaneously at several other locations within the watershed, in order to better understand the sources and fate of copper. Copper concentration, pH, and hardness were measured. Acute toxicological evaluations indicated, that although runoff was toxic at the bottom of the downspout, it exhibited no acute toxicity by the time it flowed into a stream, a state regulated waterway. Dilution, interaction with the piping materials, dissolved organic carbon and other complexing agents and debris have reduced the concentration of the potentially harmful ionic copper. Because corrosion products may be released in stormwater, corrosion engineers should play role in establishing relevant and meaningful metals discharge criteria, which protect the environment, but do not unnecessarily restrict the use of metals.en
