Drinking Water & Wells

The Snohomish County Health Department's drinking water program helps ensure that an adequate and safe, potable source of water is available to all proposed residences before construction. We also provide resources and technical assistance to homeowners with wells. 

The topics below will help you find the information you need, whether you are drilling a new well or wondering how to take care of the well you've had for years. 

If you have questions, we are here for you! Reach out by calling (425) 339-5250 or emailing SHD-EHQ@snoco.org if you can't find the information you're looking for on our website.
