Next steps for Zavalla, TX
Use a filter certified to NSF/ANSI 53 for lead on the tap you drink and cook from, now, before you test. Then test your own tap. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Raylake Wsc whether it covers that cost before hiring anyone - many utilities now do.
