Lead in Water

Quick Definition

Toxic heavy metal contamination in drinking water that causes developmental problems, especially in children

Lead contamination in drinking water occurs when lead pipes, fixtures, or solder corrode and release lead particles into your water supply. Even small amounts of lead can cause serious health problems, particularly in children and pregnant women.

What You Need to Know

Lead exposure can cause irreversible damage to developing brains, resulting in learning disabilities, behavioral problems, and reduced IQ. Adults can experience high blood pressure, kidney damage, and reproductive problems.

Why It Matters for Your Home

Homes built before 1986 are most likely to have lead plumbing components. Hot water, acidic water, and disturbed pipes can increase lead levels. Lead is colorless, odorless, and tasteless, making testing the only way to detect contamination.

How to Test for Lead

Professional water testing involves collecting samples from your tap after water has sat in pipes for several hours. EPA-certified laboratories can detect lead levels as low as 1 part per billion.

When to Get Professional Help

If testing shows lead levels above 15 parts per billion, immediate action is needed. Professional plumbers can identify lead sources, and water treatment specialists can recommend appropriate filtration systems.
