How it works
- Call or send a request with the address and the tests you need.
- We come out and take the sample the right way, in the lab’s bottles.
- We get it to the lab within its time limit. Bacteria samples have the shortest window, so we never hold them over.
- You get the lab results. For a home sale, for an added fee we can also file the paperwork with the Oregon Health Authority.
What the results mean
Bacteria, nitrate and arsenic are the health tests. Iron, manganese and hardness cause the staining, smell and scale most people notice. Our rule is test first, then treat: the results tell us what treatment, if any, the water needs.
