6ppd-q in Stormwater: the state of science and Washington Department of Ecology’s initial responses

Streaming Media

Presentation Abstract

Recent research using a novel laboratory non-targeted analysis approach has named 6ppd-quinone (6PPD-q) as the primary compound in stormwater runoff that is responsible for acute mortality of Coho salmon. This chemical is a transformation byproduct of 6PPD, an anti-oxidant and anti-ozonant that is commonly used in automobile tire rubber and is deposited on highways where it can be conveyed in stormwater runoff to streams and other receiving waters. This discovery has spurred expansive evaluation along several lines of inquiry at Ecology, the universities, and many others. This panel will start with the state of science and what we know about 6ppd-q, and its known water quality impacts and data gaps, followed by a discussion on how current research and data gaps affect management decisions. We will describe current activities to support management strategies: product substitution in tires; development of a lab analysis method for water samples; identifying available Best Management Practices (source control, treatment, and other management approaches) to control and/or treat stormwater to prevent 6ppd-q toxicity in receiving waters; and considerations to take into account when prioritizing the areas and streams affected by 6ppd-q toxicity so that treatment retrofits and other stormwater management actions can be efficiently planned and effectively implemented.
