What to do in your house
Test your own tap with a certified lab first-draw sample; Oak Creek, CO may offer free or low-cost kits through the utility. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Oak Creek Town Of whether it covers that cost before hiring anyone - many utilities now do.

What a 90th-percentile result does and does not tell you: how to read a lead result. Size matters more than most people expect: small vs large water systems.
