The Oregon Department of Environmental Quality is offering free well water testing in the Klamath Basin as part of a groundwater quality study, according to a news release.

DEQ will test 60 to 100 Klamath Basin wells for nitrate, arsenic, bacteria, pesticides and other chemicals and send property owners individual results. Knowing if contaminants exist in well water can help residents make decisions to protect their health and their crops.

Possible sources of groundwater contamination include nearby failing septic systems, current or prior application of fertilizers and pesticides, and leaking underground fuel tanks.

Property owners are responsible for maintaining and monitoring private wells in Oregon — the state does not have water quality regulations for private wells. Well water testing is only required if the property is being sold.

DEQ will provide study participants with information on proper well maintenance, the health effects of common contaminants and options for water treatment.

DEQ will collect water samples in fall 2019 and spring 2020 and send reports to property owners within six months to a year after testing. Participants must have spigot access to their well before any filtration or treatment occurs.

Sample results will be publicly available, but landowner information will not be included in the public database.

Klamath Basin is the sixth geographic area DEQ has studied as part of its Statewide Groundwater Quality Monitoring Program, which evaluates the current condition of Oregon’s groundwater.

Interested well users can contact DEQ at or 503-693-5736 to be considered for the study.
