Water testing in Lake Oswego, Oregon
Lake Oswego sits in Clackamas County, part of Oregon's Willamette Valley region. Homes and properties here are typically served by private wells and municipal drinking water drawn from valley aquifers and surface sources. The most common water-quality concerns in this area are naturally occurring arsenic in Willamette Valley groundwater, nitrate from agricultural activity and fertilizer use, and coliform bacteria in older or shallow private wells.
Our Salem laboratory is right in the heart of the Willamette Valley, so samples from your area reach us quickly — often the same day — which keeps bacteria tests within hold-time limits.
