Environmental Health Programs
Drinking Water -
WAC 246-290
and
WAC 246-291

The Drinking Water program works to ensure safe drinking water for all residents of Kittitas County, through inspections,
education, and testing.
Issues
Inspections and sampling of private water supplies is provided by an Environmental Health specialist. Resource materials
and information is available for questions concerning how to provide and maintain a safe water supply. Bacteriological testing
of water well samples is available through the Environmental Health office in partnership with the Valley Environmental
Laboratory in Yakima. This lab is state approved for water analysis.
If you are developing property and are planning to drill a well on the property, a permit for the well is required by the
Department of Ecology. That office is in Yakima (509-575-2800). A list of well drillers is available upon request from the
Environmental Health office.
Kittitas County Public Health Department monitors a percentage of wells drilled within this county for proper sealing,
tagging and decommissioning of water wells. Information about this well delegation program is available from the Environmental
Health office.
Public "group B" well systems provide water to developments with a minimum of three homesites. These systems do not exceed
the 5000 gallon usage limit per day and are considered to be "exempt" wells. An inspection for siting purposes is required for
these systems prior to drilling. Workbooks and laboratory information can be obtained from the Environmental Health office.
Kittitas County Environmental Health Department reviews and approves Group B water systems serving from three connections
(houses) to nine connections. Proposed Group B water systems to serve ten to fourteen connections are reviewed and approved by
the Washington State Department of Health at the following address:
State of Washington
Department of Health
1500 W. 4th, Suite 305
Spokane, WA 99204
Department of Health Fees will apply for Group B Water review and approval.
