Spokane River Water Quality Survey
Statement of Methodology
• Robinson Research was commissioned by The Spokane River Forum to conduct a telephone survey with adults living in portions of Kootenai County and Spokane County.
• The zip codes surveyed were all adjacent to the Spokane River.
• The telephone interviews were conducted between May 2, 2015 to May 9, 2015.
• Two summary reports are available. Kootenai County and Lincoln, Stevens, and Spokane Counties. Reports provide comparisons were made to a 2009 survey.
Statement of Methodology
• The survey was conducted as part of a public participation grant from the WA Department of Ecology.•A 200-sample survey has a margin of error of +/- 6.94%
percent. In theory, survey results have a ninety-five percent (95%) chance of coming within +/- 6.94 percentage points of results that would have been obtained if all households in zip codes adjacent to the Spokane River had been interviewed.

Relationships and Trust
• In both states, conservation districts and state/local health agencies scored very well when asked their level of “trust and confidence in them managing restoration or clean-up efforts in the Spokane River.” • In both states, there is less trust and confidence in EPA relative to
others, with ID trust/confidence being significantly lower. • WA respondents have much higher trust/confidence in non-profit
environmental groups than ID respondents. • There is positive trust/confidence, although it varies somewhat
from state to state, in Scientists/Professors, Tribes, Environmental State Agencies, and Cities/Counties.
