A CASE FOR MODERNIZING WATER QUALITY CRITERIA
Methods for establishing Water Quality Criteria for the protection of Aquatic Life in the United States were established in 1985. The US EPA is currently considering modernizing this process. Presently, the only information used to inform criteria is a compilation of single species toxicity bioassay data from a handful of “surrogate species”. Other forms of information are currently not used in criteria development. I will summarize decades of research with trace metals that demonstrates how/why using only data collected from a single methodology fails to provide relevant and important science to best inform water quality criteria development. In particular, I will discuss the importance of relevant toxicity test organisms and protocols, particularly those that consider dietary exposures to bioaccumulative contaminants. I will also discuss the prospects for integrating traditional toxicity bioassays with other laboratory approaches, mesocosm, and field survey data.
