On October 8, 2024, the EPA introduced a new rule that requires all drinking water systems in the U.S. to identify and replace lead pipes within 10 years. As part of this initiative, Montana will receive nearly $25 million in funding to support local efforts in ensuring clean, safe drinking water for all households.

For Montana families, this regulation provides a vital opportunity to protect their health, especially given the serious risks posed by lead exposure. Lead pipes, often used in older infrastructure, can leach harmful contaminants into drinking water, leading to significant health problems. This is particularly concerning for children, as lead exposure can cause developmental delays, cognitive impairments, and long-term physical health issues in adults.

Here’s how the new law will impact Montana residents and what homeowners can do to identify and address lead pipes in their homes.

What Does the New Lead and Copper Rule Mean for Montana?

Under the new Lead and Copper Rule Improvements (LCRI), water utilities are required to:

• Identify all lead pipes in their service areas within the next 10 years.
• Increase testing rigor, lowering the lead contamination threshold that necessitates action.
• Improve communication with residents about the risks of lead and the progress of pipe replacements.

Montana has been allocated $24.9 million from the EPA’s funding pool, giving local water utilities the financial support to map, test, and replace lead pipes. At least 49% of the funding will be directed toward disadvantaged communities, ensuring that resources are available where they are most needed.

How Homeowners Can Identify Lead Pipes

While Montana’s water utilities will take steps to map lead pipes, homeowners can also identify potential lead risks in their homes:

1. Perform Material Tests: Inspect the pipes where they enter your home. Lead pipes are typically a dull gray and can be scratched with a key or coin to reveal a shiny metal beneath. Lead pipes are also non-magnetic and tend to produce a dull thud when tapped.
2. Test Your Water: You can have your water tested by a certified professional if you suspect contamination. Local health departments often offer free or low-cost testing kits. This will confirm whether your home’s drinking water contains lead.
3. Confirm Plumbing Age: Homes built before the 1980s are more likely to have lead pipes, though lead plumbing may still be present in homes built before the 1990s. If you’re unsure about your home’s plumbing, consider having it inspected by a professional.
