Where the water comes from
City of Magnolia's main water source is groundwater (wells). It buys treated water from Grand Oaks MUD. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while City of Magnolia is responsible for its own service line inventory and replacement program. It sells water to 3 other water systems: Grand Oaks MUD, Audubon MUD 1, Audubon MUD 2.

Check your own address
These counts cover the whole system. To see whether your line is lead, use the utility's address-level inventory. Utilities had to prepare one by October 16, 2024 and make it publicly accessible; systems serving more than 50,000 people must post it online.

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. Ask City of Magnolia whether it replaces the private side for free or with a cost share before you hire anyone. If you want it done sooner, or your utility doesn't cover your side, a licensed plumber can quote it. What replacement costs.
