Managing our water is one of the biggest challenges of the 21st Century.

Clean, abundant water was once taken for granted in Washington state as a free, unlimited resource. Today, after more than a century of dramatic population growth and climate change we know our water resources are not unlimited and certainly not free.

Population growth and associated development increase the demand for clean, abundant water and increase pollution problems.

Ecology’s water programs are working closely with Washington communities to clean up and protect water quality in Washington. They also work to ensure the state has clean, adequate water supplies that meet current and future drinking water needs, commercial and agricultural uses, and to sustain fish and the natural environment.

We remain committed to protecting and enhancing the quantity and quality of our water resources even in challenging economic times. Ecology embraces local partnerships and citizen involvement in our efforts to ensure a water smart future in the 21st Century.
