How did we get here?
Our water treatment plants are not a source of lead. If lead or copper is found in tap water, it is typically caused by underground pipes, plumbing, solder, or fixtures in older buildings. Here’s some history on lead in water systems:
- Congress amends the Safe Drinking Water Act, prohibiting the use of pipes, solder, or flux that are not “lead free” in public water systems or facilities providing water for human consumption.
- EPA publishes the LCR to minimize lead and copper in drinking water. Since then, it has undergone various revisions.
- EPA announces proposed Lead and Copper Rule Improvements (LCRI). A key provision is achieving 100% lead pipe replacement within 10 years.
- Water systems are required to provide an initial inventory of their lead service lines by Oct. 16, 2024.
