Description:
A study was conducted on the interrelationships of corrosion rates, metal concentrations, and water quality occurring within galvanized steel and copper plumbing systems. A comprehensive water sampling program was implemented to quantify the total metal concentrations and the major inorganic constituents found in standing and running water samples. Corrosion rates were measured by using the ASTM D2688 corrosion tester. Lead, zinc, copper, iron, and manganese exceeded the MCL in 10.6% to 25.6% of the standing samples and in 2.2% to 16.0% of the running samples collected.
