OLYMPIA – Washington’s waters could soon see more protective limits for dozens of toxic chemicals, meaning cleaner water and a healthier environment for all creatures that call our state’s rivers, streams, and Puget Sound home.
The Department of Ecology is proposing a major update to the state’s aquatic life toxics criteria.
As part of the state’s rules for how clean state waters need to be, the aquatic life toxics criteria are designed to protect aquatic life, such as fish and invertebrates, from the effects of toxic chemicals in the water.
Washington’s last major update to these criteria was 30 years ago. Ecology is proposing these updates now based on updated science and new research, new methods and modeling tools, recommendations from EPA and Tribal governments, and public input encouraging Ecology to prioritize this work.
Once finalized by Ecology and approved by the U.S. Environmental Protection Agency, the updated criteria will become part of water quality permits and used to identify polluted waters that need cleanup plans.
The criteria include limits for marine and freshwater, and limits to protect aquatic life from both immediate (acute) effects, such as death, and long-term (chronic) effects, such as changes in growth and reproduction.
Currently, Washington has aquatic life toxics criteria for 28 toxic chemicals.
Currently, Washington has aquatic life toxics criteria for 28 toxic chemicals.
Ecology is proposing to update the criteria for 16 these chemicals and add 14 more chemicals to the list for a total of 42. Well-known chemicals already on the list such as arsenic, copper, nickel, silver, zinc are receiving updates to better protect aquatic life from these chemicals.Proposed new additions to Washington’s list include PFOA and PFOS (part of the PFAS chemical group), aluminum, and the emerging chemical of concern 6PPD-quinone, the chemical that comes from tires and is toxic to salmon.
