What to do in your house

Test your own tap with a certified lab first-draw sample; Novato, CA 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 Ramblewood Mobile Home Park 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. The action level is dropping - the 10 ppb rule from 2027.
