Title:Foundation Knowledge Webcast: Impact of Galvanic Corrosion on Partial Lead Service Line Replacement
This Webcast presents findings from project #4349, supported by the Water Research Foundation, the District of Columbia Water and Sewer Authority, and the Providence Water Supply Board, to examine the issue of lead in drinking water following partial lead service line replacements (LSLRs). Partial LSLRs are the result of divided ownership of the customer service line, and they can result from required regulatory replacements or can be incidental to infrastructure renewal or repair efforts by the utility. The Webcast reports on two experimental programs that examined lead release in controlled laboratory settings using different types of commercially available couplings. It also reports on long term field data from partial LSLRs in the two participating utilities, which were done as part of large lead service line replacement programs. The final report for this project will be available before the Webcast on the #4349 project page.
