What you should know about lead service line replacement requirement updates

In October 2024, the U.S. Environmental Protection Agency (EPA) announced the final Lead and Copper Rule Improvements (LCRI) to strengthen efforts to reduce lead exposure in drinking water. The final LCRI builds upon the previous lead and copper rules and includes key provisions proposed by the agency in November 2023. The rule is effective Dec. 30, 2024.

Establishing a timeframe to replace lead service lines will protect public health. The EPA estimates that the rule will protect infants and children from developmental delays and health conditions associated with lead exposure.

This blog post explains the final lead service line replacement requirements and why communities should partner with an expert to upgrade their water infrastructure.

What are the updated lead service line replacement requirements?

​The proposed LCRI provides an option for water systems with more than 100,000 lead service lines to defer deadlines by replacing 10,000 service lines per year. The final LCRI simplifies the deferral mechanisms so that systems with a high proportion of lead service lines are eligible to extend deadlines, regardless of their total number of service lines. The following table highlights the key lead service line replacement requirements under the final rule.

LCRI

  • Achieving lead service line replacement within 10 years. All water systems should replace lead service lines within 10 years after the compliance date. For some drinking water systems, in limited circumstances, the rule established additional time to get the job done.
  • Locating legacy lead pipes. Regulated water systems should have completed initial inventories of their lead service lines and should keep inventories updated. Water systems should also develop a service line replacement plan, prioritizing communities disproportionately affected by lead exposure.
  • Improving tap sampling. Water systems should collect first- and fifth-liter tap samples at sites with lead service lines and use the higher of the two values to determine compliance.
  • Lowering the lead action level. The final rule reduces the lead action level from 15 micrograms per liter (µg/L) to 10 µg/L. A water system exceeding this should inform the public and take action to reduce lead exposure while expediting the replacement of all lead pipes.
  • Strengthening protection to reduce exposure. Water systems with multiple lead action level exceedances should continue adjusting treatment, conduct additional community outreach and make filters certified to reduce lead available to all consumers.

Water systems must comply with the lead service line replacement requirements starting three years after the rule is in effect. Water systems should also comply with certain elements of the Lead and Copper Rule Revisions (LCRR), including:

The lack of funds is a major obstacle to lead service line replacements across communities. Taking this into account, the EPA announced $2.6 billion in available drinking water infrastructure funding to support lead pipe replacement projects. The total funding through the Bipartisan Infrastructure Law that can be used for lead line replacements is more than $26 billion over five years. Half of this funding will go to disadvantaged communities as grants or principal forgiveness loans.
