Water quality testing requirements differ between Washington and Oregon. 

In Washington State, the requirement for well water testing, as a part of a real estate transaction, is up to the discretion of the county health and/or planning department, or even your lender. 

In Oregon, however, this is regulated at the state level, through the Oregon Health Authority.

Generally your real estate agent will be versed in the regulations and requirements around this topic, but we recommend you take the time to educate yourself, and find out what you are required to do (or legally entitled to) based on your jurisdiction! 

What is water quality testing (WQT)?

Water quality testing is simply the collection, transport, delivery, and processing of a sample of drinking water, taken from a source to a laboratory for processing and reporting.

In terms of testing for a real estate transaction, the source of testing would be from a private water source (a well).

What contaminates are typically tested for?

The 3 most common contaminates, with regard to private water sources, are Nitrates, Arsenic, and Coliform Bacteria.

The rules and regulations in each state are generally drawn up with these 3 contaminates in mind, but no matter which state you reside in, your specific county may have additional requirements for testing.

Your real estate agent should be well versed in your local requirements for WQT, but it is still a good idea to call the local health department in advance and ask them if there is anything else that needs to be, or should be tested for.

Is this something that I can do myself?

Absolutely! All you have to do is simply contact a certified laboratory in your area who can process water samples submitted for testing, follow their instructions for collection and delivery, and simply wait for your results.

Bear in mind that when contacting a laboratory, each contaminate being tested for is a separate test, with separate fees.
