Where the water comes from
City of Berthold's main water source is purchased groundwater. It buys treated water from Northwestern Area Water Supply. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while City of Berthold is responsible for its own service line inventory and replacement program.
