Description:
Future drinking water regulatory action may require some water utilities to consider additional and/or alternative oxidation and disinfection practices. There is little known about the effect of oxidant changes on the corrosion of drinking water distribution system materials and the release of metals from corrosion by-products. This redox study implements an experimental loop apparatus system to evaluate the corrosion of metals in drinking water. Lead, copper, iron and red brass coupons are placed in a controlled reaction cell. The results of this science will further allow EPA to provide guidance on corrosion control in our aging distribution systems as well as treatment approaches for reducing metal levels at the consumer’s tap.
