Next steps for Klawock, AK
Test your own tap with a certified lab first-draw sample; Klawock, AK may offer free or low-cost kits through the utility.

Why sampled homes are the worst-case ones is in the guide to reading the number. Size matters more than most people expect: small vs large water systems.
