Your move
Test your own tap with a certified lab first-draw sample; Corvallis, OR may offer free or low-cost kits through the utility.

Ask Alsea County Service District whether it covers that cost before hiring anyone - many utilities now do.

The lead result guide covers how utilities pick the homes they sample. Size matters more than most people expect: small vs large water systems.
