Water quality survey
Since 1999, the county's Department of Natural Resources and Parks (DNRP) has commissioned a water quality survey to get feedback on water quality issues from King County residents.
The survey is conducted by an independent research firm that randomly polls over 500 King County residents age 18 and older.
The survey helps us understand how we're meeting our values and goals, allows residents to rate environmental issues in our region, and measures support for recycled wastewater products (biosolids, reclaimed water) and increased funding for services.King County DNRP used to conduct the survey annually, and made a decision in 2007 to do it every two years as a cost-saving measure. We will commission the next survey in 2019.
- King County’s positive ratings for the job providing wastewater treatment services has declined from 2015.
- Awareness of King County wastewater services is at an all time high, however resident recall is dominated by recent negative news stories around the West Point Treatment Plant failure.
- Intensity of importance has increased for the list of things King County is doing to protect water quality across the region.
- Most residents strongly support King County’s plans to invest in the reduction of combined sewage overflows (CSO).
- The overwhelming majorities continue to favor using recycled biosolids and recycled/reclaimed water.
