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

Ask Enchanted Oaks Wsc 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.
