Frequently Asked Questions

How can I locate drinking water records?
Many records are available online through our office, here. If we do not have your information on file, please email us or contact the Department of Ecology (360-715-5200) to search for a well log.

How do I get my water source approved to obtain a building permit?
You will need to go through a process called water availability approval. Please allow up to one week for a decision to be made on your approval once your completed water availability application is submitted to our office. Sometimes applicants must conduct additional testing or submit additional paperwork because of the well location. Water availability application forms for single party, shared, and public water sources are located here.

What do I need to do to have a well drilled?
The Department of Ecology is responsible for well drilling regulations and requirements. Information on drilling a well can be found here or contact a licensed well driller.

Does it matter where I drill my well on my property?
Yes, you should locate the well at least:

  • 50’ from your septic tank
  • 100’ from your drainfield
  • 100’ from any privy or outhouse
  • 50’ from a sewer line
  • 100’ from a sewage or manure lagoon
  • 1000’ from any parcel containing a landfill (active, inactive, closed, or illegal)

How deep will I have to drill my well?
The depth to ground water varies from area to area in Whatcom County so you will not know for certain until you drill your well. You may get an idea by talking to a neighbor, contacting a well driller or looking on our depth of well map in our office.

What do I have to do to develop my own public water system?
The information and application packet are located here.

How do I find out who takes care of the public water system that serves water to my house?
Please email us at Environmentalhealth@whatcomcounty.us.

My water is making me sick, what should I do?
Stop drinking the water. If the severity of your illness concerns you, contact your health care provider and they can help you with any necessary treatment to help get you well. Contact our office for help in determining why the water you drank may have made you sick.

Where can I find information on water treatment systems?
Information on water treatment systems can be found on the National Sanitation Foundation’s website.
