The City of Wadsworth is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing materials. Corrosive water can cause the lead in those components to "leach" into the water.
Wadsworth is lucky to get its water from wells, which helps ensuring it is non corrosive much easier. Although we had already stable water and had never had an issue with lead and copper testing, in 1998 Wadsworth started a voluntary corrosion control program.
It was determined that we should feed Zinc Orthophosphate to the water. This chemical coats the water line with a protective layer that prevents any lead from leaching out of the pipes.
