Guidance for Harvested Pipe Studies to Inform Lead and Copper Corrosion Control Treatment Decisions

Key Takeaways Pipe rig tests using harvested pipes are commonly used to understand lead and copper corrosion control treatment (CCT) options. Involving planning, design, operation, and data analysis as key components, pipe rig tests are in some cases required by the Lead and Copper Rule Improvements. As summarized here, guidance for pipe rig flow‐through studies to inform lead and copper CCT is provided in Water Research Foundation Project 5081. Pipe rig tests are conducted at a water treatment plant, in the distribution system, or in a remote lab; costs vary depending on rig type, testing range, and site‐specific characteristics.
