The primary source of lead and copper in a drinking water system is from private plumbing systems including the service line from the meter and the piping inside homes (copper piping with solder containing lead or a lead-based service line). Lead soldering of copper water pipes was banned in Georgia in 1985, but some homes still contain these plumbing systems. Per federal regulation, the City of Roswell tests locations with these at‐risk plumbing systems to ensure our corrosion control technique is effective. Since 2015, the Roswell Water Utility has used only lead‐free brass fittings and continues to proactively replace aging pipe in our system.
