3 Key Takeaways:
- A homeowner’s decision to replace their lead service line can be confounded by factors including their understanding of the science, their perceptions of their lead exposure risks, and the cost of the work.
- First draw and 5-minute flush samples may not capture the peak lead concentration, further confounding a customer’s replacement decision.
- In my case, lead service line replacement significantly lowered lead concentrations after stagnation based on sequential sampling.
