Environmental Health Specialist
The Drinking Water program works to ensure safe drinking water for all residents of Kittitas County,
through inspections, education, and testing.
Resource materials and information for private water systems are 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 and Cascade
Analytical in Union Gap. These labs are 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) 575-2490. 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 three to 14 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.
Department of Health Fees will apply for Group B Water review and approval.
For the Group B workbook and appendices go to the
Washington State Department of Health website
and search by publication number.
A complete Group B Water System Packet containing all forms, Group B workbook, and Group B Water System
Guidelines is also available for $8.00 at the Kittitas County Public Health Department, 507 N Nanum
St, Suite 102, Ellensburg.
