What to do in your house
Look up your address in Danbury Water Dept-Ridgeview Gardens's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask Danbury Water Dept-Ridgeview Gardens 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. Why sampled homes are the worst-case ones is in the guide to reading the number. A zero today does not rule out a jump later - the rules are tightening in 2027.
