Inventory of Lead Service Lines

Since 1994, Summerville CPW has monitored lead and copper concentrations in the drinking water from a group of residences constructed prior to 1986, when the national ban on the use of lead in water lines went into effect. All results have been below the EPA action level. Summerville CPW completed an inventory of all service line materials using data collected from decades of maintenance and inventory records, interviews with long-time employees, and an EPA-approved statistical model. Based on this data and the results from regular sampling, Summerville CPW can certify with a high level of confidence that no lead service lines are present in its water distribution system. The inventory is regularly updated as construction work is completed, and more data is gathered.
