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

Ask Arrowhead Mobile Home Park 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.
