Your move
Test your own tap with a certified lab first-draw sample; Cataula, GA 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 Harris County Water System whether it covers that cost before hiring anyone - many utilities now do.
