Lead service line (LSL) replacement, particularly a partial replacement, creates the potential for continued elevated levels of lead for a period of days to months. However, the need for post-replacement measures is reduced when the entire service line is replaced and is most directly related to the lead content in the rest of the home’s plumbing.
