What to do in your house
Test your own tap with a certified lab first-draw sample; Sugar Land, TX may offer free or low-cost kits through the utility.

Ask Kingdom Heights Water System whether it covers that cost before hiring anyone - many utilities now do.

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.
