Citizen Suit Alleges Violations of Safe Drinking Water Act and WashingtonvState’s Non-Endangerment Standard for Underground Injection Control Wells
Edmonds, WA –Olympic View Water and Sewer District (OVWSD) has issued a Notice of Intent to Sue to the Edmonds School District to protect the drinking water aquifer that is threatened by PFAS (Per- and Polyfluoroalkyl Substances) pollution at the Madrona School. This legal action cites violations of environmental laws and follows the school district’s inaction in addressing the pollution.

One of the main pollution sources from urban and suburban communities is stormwater. Stormwater is rain and snow melt that flows over rooftops, streets, landscaping, and parking lots that can pick up and carry pollution into nearby waterways. Stormwater is not always treated even when it flows into street drains and can be a leading threat to water quality. Due to the significant rain and snow across the state, Washington has become a leader in stormwater management.

Per-and Polyfluoroalkyl Substances or “PFAS” has become an issue of public health concern in numerous contexts recently including in public drinking water supplies. PFAS are a large family of chemicals in use since the 1950s to make a wide variety of stain-resistant, water-resistant, and non-stick consumer products, including food packaging, outdoor clothing, and non-stick pans. PFAS have also been used in certain types of firefighting foams utilized by the U.S. military, local fire departments, and airports.

Vehicle tires contain the chemical known as 6PPD to prevent tires from breaking down due to reactions with ozone and other reactive oxygen species in the air. When 6PPD reacts with ozone in the air, it forms 6PPD-quinone. Tires wear down through contact with roads, releasing particles into the environment. When it rains, stormwater from hard surfaces like parking lots and streets washes these particles into streams and other water bodies. As a result, 6PPD-quinone may be present and aquatic organisms can be exposed to it.

EPA is committed to providing meaningful, understandable, and actionable information on per- and polyfluoroalkyl substances – known as PFAS – to the American public. The information provided here is intended to explain some of the important background information needed to understand the details of specific actions EPA takes to address PFAS, and other emerging events related to PFAS.

Passed into law in 1988
The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law. MTCA funds and directs the investigation, cleanup, and prevention of sites that are contaminated by hazardous substances. It works to protect people’s health and the environment, and to preserve natural resources for the future.
There are about 14,000 known or suspected contaminated sites in Washington — and the list keeps growing. Thanks to cleanup efforts funded by MTCA, more than 7,700 of these sites are already cleaned up or require no further action.

On April 10, 2024, EPA announced the final National Primary Drinking Water Regulation (NPDWR) for six PFAS. To inform the final rule, EPA evaluated over 120,000 comments submitted by the public on the rule proposal, as well as considered input received during multiple consultations and stakeholder engagement activities held both prior to and following the proposed rule. EPA expects that over many years the final rule will prevent PFAS exposure in drinking water for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious PFAS-attributable illnesses.

WASHINGTON (AP) — The Environmental Protection Agency on Friday designated two forever chemicals that have been used in cookware, carpets and firefighting foams as hazardous substances, an action intended to ensure quicker cleanup of the toxic compounds and require industries and others responsible for contamination to pay for its removal.

On March 3, 2021 (86 FR 12272; USEPA, 2021a), the United States Environmental Protection Agency (EPA) announced its decision to regulate perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) under the Safe Drinking Water Act (SDWA).

The methods used to conduct the systematic review for PFOA are consistent with the methods described in the draft and final EPA ORD Staff Handbook for Developing IRIS Assessments (U.S. EPA, 2022b, 2020a) (hereafter referred to as the Integrated Risk Information System (IRIS) Handbook) and a companion publication (Thayer et al., 2022).

6PPD is a chemical that prevents automotive tires from degrading (i.e., breaking down) and helps them last longer. When 6PPD is exposed to air, it reacts with ozone to create 6PPD-quinone (also known as 6PPDQ). 6PPDQ is lethal to coho salmon and can contaminate water systems.
We work with Tribal and local governments, state and federal agencies, academic institutions, and industrial organizations to reduce the pollution and sources of 6PPDQ released from tires in Washington.

A brief history of PFAS
Per- and polyfluoroalkyl substances are collectively known as PFAS. The group comprises thousands of unique synthetic organic chemicals that are extremely stable and persistent. Commercially manufactured since the 1940s, PFAS compounds have been used in manufacturing common consumer products, such as carpeting, clothing, furniture, outdoor equipment, and food packaging. Many industries have also used PFAS, including aerospace, automotive, aviation, electronics, and medical industries. One major source of PFAS contamination is Aqueous Film Forming Foam (AFFF), which is used for fire training and extinguishing petroleum fires and other flammable liquids.
