Event description


Lead service line (LSL) replacement is not a simple task. The LSL Replacement Collaborative has developed an online toolkit to help communities across the United States develop and implement replacement programs and is hosting a series of webinars to address specific topics related to this work.

This webinar in the Collaborative's series will address flushing!

Lead enters drinking water when water is stagnant in contact with lead. Flushing, to cleanse or wash out with a rush of water, plays a role in reducing lead exposure, before, as part of, and following lead service line replacement. During this webinar, speakers will describe the roles of flushing, strategies for flushing for specific purposes, and example community-specific communication efforts to encourage effective flushing. Research is ongoing to improve our understanding of flushing practices. This webinar will capture the latest information from these research efforts.
