Next steps for Brookfield, CT
Test your own tap with a certified lab first-draw sample; Brookfield, CT 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 Brookfield Housing Authority whether it covers that cost before hiring anyone - many utilities now do.

The lead result guide covers how utilities pick the homes they sample. Why an old exceedance still matters: over the limit before, under it now.
