Semiannual Lead & Copper Results

In compliance with the Lead and Copper Rule, PWCSA analyzes water distributed to customers to assure that it is not corrosive. Corrosion control is needed to prevent dissolution of lead from lead solder in older homes and extend the life of household pipes. PWCSA water suppliers, Fairfax Water and the City of Manassas, add corrosion inhibitors that contain phosphate.
