This powerpoint presentation begins by providing background information on lead and copper source in drinking water, the use of granular activated carbon (GAC) filters and possible impacts on corrosion, nitrification effect on corrosion, and a pipe rig setup diagram. GAC treatment is presented with topics covering: representative waterchemistry changes by GAC; pH change; and, effect of GAC treatment on copperand lead release. Nitrification is presented, including: pH changes in pipes; PVC pipes; and, copper-lead rigs. Effect on Lead and Copper Release is presented in terms of: Copper-Lead rigs; Lower pH in PVC Pipes AffectsDownstream Brass Faucet Corrosion; and, Lead and Copper Release in Copper-Solder and Copper-Brass Rigs.
