Where the water comes from
Wyoming City PWS's main water source is groundwater (wells). It buys treated water from Cincinnati Public Water System. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Wyoming City PWS is responsible for its own service line inventory and replacement program.

Protect your drinking water now
If your line is lead, galvanized or unknown, filter water for drinking, cooking and baby formula. Use a filter certified to NSF/ANSI 53 for lead. Run cold water for a few minutes after it sits for hours, and never use hot tap water for cooking.

Getting the line replaced
EPA's Lead and Copper Rule Improvements require most systems to replace lead and galvanized-requiring-replacement lines by December 31, 2037.
