Where the water comes from
PA American Audubon's main water source is purchased surface water. It buys treated water from PA American Norristown. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while PA American Audubon 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.
