Water Challenges Unique to Thurston County

Thurston County sits at the south end of Puget Sound and relies heavily on groundwater. City systems such as Olympia and Lacey pump from wells, and many homes outside city service have private wells of their own.

Olympia’s main source is the McAllister Wellfield, and the Washington Department of Health notes its groundwater has a naturally low pH that the city treats to protect pipes. Lacey reports that all of its water comes from groundwater wells drawing on three aquifers.

On city water, the most common request is better taste and smell. On private wells the owner is responsible for testing, and results can vary from one well to the next, even between neighbors.

Testing and local guidance

Thurston County’s environmental health water lab in Olympia runs bacteria and nitrate tests on drinking water samples. Confirm current drop-off times with the county before you go.

Frequently Asked Questions in Thurston County

Where does Olympia’s water come from?

The city’s primary source is the McAllister Wellfield, supplemented by additional wells. It is all groundwater.

Where does Lacey’s water come from?

The City of Lacey says all of its drinking water comes from groundwater wells that draw on three aquifers.

Do Thurston County private wells need testing?

Yes. Private wells are not regulated like public systems, so the owner is responsible. The county water lab in Olympia tests drinking water for bacteria and nitrate.

Why does my city water taste like chlorine?

Public systems add disinfectant to keep water safe on its way to your home. A carbon filter removes most of the chlorine taste and smell.

Which system is right for my home?

It depends on your source and your goals. Our team reviews your water, explains the options clearly, and recommends a system that fits your budget.
