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

Ask Modesto Irrigation District whether it covers that cost before hiring anyone - many utilities now do.
These figures describe homes the utility sampled, not your tap. Only your service line record or a test of your own water answers the question for your house. The lead result guide covers how utilities pick the homes they sample. Systems that went over once often dip back under; here is what that means.
