Effectiveness of Lead Pipe Replacement
Legacy plumbing materials pose lead contamination hazards to drinking water, and a growing number of communities are working to phase them out. Particular challenges exist in economically distressed communities where strategic lead source removal may be required to maximize the benefits. Flint Michigan’s pilot program to replace lead service lines will be examined in this study to assess the role that water distribution system hydraulic factors and community socioeconomic issues play in the success of lead pipe replacement programs. The research will assess 1) whether full or partial removal of lead service lines sufficiently reduces lead exposure, 2) whether hydraulic factors are important criteria to target problem areas, and 3) identify the most important social and economic factors that hinder remediation efforts. Outreach to help the Flint community develop and prioritize strategies to achieve a safe water supply will be undertaken.
