Lead service lines
Ask your utility first
Blount County Water Authority reported 5 galvanized service lines to replace in EPA’s inventory (2026Q2). Many utilities replace these lines for free or share the cost. Ask Blount County Water Authority whether your home’s line is on its list before you pay anyone.
Your path: I live in an older buildingLead from plumbing is the main question
Older buildings may have lead service lines, solder or fixtures. Blount County’s utility reported 5 galvanized service lines in EPA’s inventory. Test first-draw water, then filter if needed.
Your path: My water tastes of chlorineThe disinfectant is not in this record
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
