SETAC Globe Preview Article: Special Session in Long Beach to Reflect on 40th Anniversary of the Clean Water Act
Karen Setty, Southern California Coastal Water Research Project and John Toll, Globe Editor-in-Chief
When the Clean Water Act was enacted in the United States on 18 October 1972, no forum existed for interdisciplinary communication among environmental scientists—biologists, chemists, toxicologists—as well as managers, engineers and others interested in environmental issues. SETAC was founded in North America in 1979 to help fill this void. SETAC’s tripartite structure, then as now, makes it an important venue for members of the water quality research and regulatory community to interact and to build a scientific foundation protected against institutional bias.
The upcoming SETAC North America 33rd Annual Meeting in Long Beach falls within a month of the 40th anniversary of the Clean Water Act's enactment and offers a timely opportunity to pause and reflect on the changes in America's waterways stemming from the enormous decades-long collective efforts of environmental scientists, engineers, advocates, managers and policy-makers.
A special symposium will be held Monday, 12 November (in room 201A) from 8:00 a.m. to 12:00 p.m. focusing on how the Clean Water Act influenced water quality conditions across the country. The session includes case studies on the primary goals of the Clean Water Act (ensuring swimmability, fishability and ecosystem protection), as well as remaining challenges and lessons for the future. The speakers will represent freshwater and marine aquatic habitats from southern California, San Francisco Bay, Puget Sound and the southeastern US.
Research done by SETAC members has had a major influence on water quality science and regulation. Environmental Toxicology and Chemistry (ET&C) has published key papers in a number of areas important to the Clean Water Act. Among the first was a paper on deriving acute to chronic ratios (ACR) for fish and aquatic invertebrates (Kenega 1982). The ACR is still used today to derive chronic water quality criteria. A few years later ET&C published an editorial entitled “Has the Water Quality Criteria Concept Outlived its Usefulness?” (Kimerlee 1986). The author’s answer was a qualified no, which is probably the conclusion many would still reach today. That same year, ET&C published a paper on using in-stream monitoring data to derive site-specific water quality criteria (Van Hassel and Gaulke 1986). Further, among ET&C’s most highly influential papers (as measured by frequency of citation) are publications on aquatic toxicity test methodology (e.g., Mount and Norberg 1984; Williams and Dusenbery 1990), water and sediment chemistry effects on metals toxicity (e.g., Erickson et al. 1996; Ankley et al. 1996; Berry et al. 1996; Di Toro et al. 2001; Santore et al. 2001) and derivation of sediment quality benchmarks based on equilibrium partitioning theory (e.g., Di Toro et al. 1991). These seminal papers just scratch the surface of the influential body of work published by ET&C on water quality science and regulation.
In recent years Integrated Environmental Assessment and Management (IEAM) has provided another outlet for publishing in areas important to the Clean Water Act. Examples include papers on protectiveness of water quality criteria (e.g., Van Genderen et al. 2008; Gensemer et al. 2009; DeForest et al 2011a; DeForest et al 2011b; Guy et al. 2011; Gilron 2012; McLaughlin 2012), development and testing of new models and methods for deriving water quality criteria (e.g., Arnold and Warren-Hicks 2007, Natale et al. 2007, Slaughter et al. 2007, Arnold and Cotsifas 2008; Cormier et al. 2008; Adams et al. 2011, Meador et al. 2011, DeForest et al. 2012) and watershed-scale water quality assessment (e.g., Stubblefield et al. 2005; Flinders et al. 2009; Merot et al. 2009; Seitz et al., 2012).
Workshops are another SETAC forum that has played an important role in the development of water quality science and regulation, since the early days of the Clean Water Act. The first half-dozen Pellston workshops (1977-1984) tackled important topics in water quality science and regulation. Subsequent SETAC workshops covered many other important topics, but to this day water quality science and regulation remain important recurring themes for SETAC workshops:
- Estimating the Hazard of Chemical Substances to Aquatic Life (1977)
- Analyzing the Hazard Evaluation Process (1978)
- Biotransformation and Fate of Chemicals in the Aquatic Environment (1979)
- Modeling the Fate of Chemicals in the Aquatic Environment (1981)
- Environmental Hazard Assessment of Effluents (1982)
- Fate and Effects of Sediment-Bound Chemicals in Aquatic Systems (1984)
- Aquatic Microcosms for Ecological Assessment of Pesticides (1991)
- A Mechanistic Understanding of Bioavailability: Physical-Chemical Interactions (1992)

- Tissue Residue Approach for Toxicity Assessment: Invertebrates and Fish (2007)
- Science-Based Guidance and Framework for Evaluation and Identification of PBTs and POPs (2008)

Clearly, SETAC and the Clean Water Act have grown up together! Come to hear diverse perspectives and share in the discussion, as SETAC joins the nation in celebrating successes from the first 40 years of the Clean Water Act and planning to tackle the emerging issues of the next 40 years.
