Your move

If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Morenci whether it covers that cost before hiring anyone - many utilities now do.

What a 90th-percentile result does and does not tell you: how to read a lead result. The action level is dropping - the 10 ppb rule from 2027.
