Where does Chilhowie's water come from?
Chilhowie's drinking water comes from gup, supplied by 2 water systems serving approximately 4,625 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include S F Holston River (river), M F Holston River (river), N F Holston River (river).
What Chilhowie residents can do
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
Chilhowie's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
