Query Form
Safe Drinking Water Query Form for the State of Washington
This query form allows you to retrieve Safe Drinking Water data from the SDWIS database in Envirofacts. You may select among four possible search options: water system name, county name, population served, and/or system status.
Disclaimer: Some data may have been entered into SDWIS without a "county served" designation. In those cases, you will either need to search by "Water System Name" (check your water bill for that information), or create a STATE search (click on "Search" button without any other entries), and select your water system from that list.
