ECOSS is a non-profit organization working with Puget Sound neighborhoods towards building an environmentally responsible community. We serve as a voice for the community on issues that encourage a clean environment and urban redevelopment. Through education and outreach, ECOSS helps businesses and individuals - many of whom are not native English speakers - prevent pollution, conserve energy, manage hazardous materials and clean up contaminated properties.

ECOSS was established in 1994 to address challenges over the imbalance of the South Park neighborhood and lower Duwamish River. By bridging the interests of residents, industry, and government, the organization has created a model that is both sustainable and mutually beneficial. Over the years our work has expanded in range and scope as other communities have recognized the benefits of this holistic approach.

By offering free and confidential services, ECOSS has developed a niche within the Puget Sound area as a trusted source of environmental education and a link to sustainable resources. Our suite of services includes:

• Phase I Assessments of Contaminated Properties
• Stormwater Pollution Prevention and Education
• Energy and Water Conservation Assistance
