Lead in Drinking Water: Risks, Sources, and How to Protect Your Home

Unbeknownst to many homeowners, lead can contaminate our drinking water. This hidden risk has no taste, color, or smell, yet a small amount can pose serious health concerns, especially for young children. In this article, we'll discuss where it comes from, the risks it carries, and how reducing exposure is essential for protecting your household's water and long-term health.

How Does Lead Get into Drinking Water?

Lead rarely occurs naturally in source water; instead, it finds its way through via plumbing. Many older homes have lead service lines, copper pipes, or brass fixtures that contain small amounts of lead. Over time, corrosion can cause this lead to enter the water supply. Even homes without lead pipes can still receive trace amounts from faucets and fittings.

Water that has been sitting in pipes for several hours has a high likelihood of lead dissolving into it. This is why "first-draw" water from the tap often has the highest lead levels.

The Health Risks of Lead Exposure (Especially for Children)

Lead is a toxic metal with no safe level of exposure. Once it enters the body, it can accumulate over time and affect multiple organs and systems. The brain and nervous system face the most impact, with children being particularly vulnerable. Infants and young children who are exposed to lead may experience developmental delays, learning difficulties, reduced IQ, and behavioral issues. Because their bodies are still developing, even the smallest amount can have lasting consequences. Unborn babies are also at risk, as lead can cross the placenta and affect the development of the fetus.

In adults, lead exposure can lead to high blood pressure, kidney problems, and neurological effects, although symptoms are often less obvious. What's concerning is that lead exposure is invisible. There's no taste, smell, or color to signal its presence in our water.

Is Lead a Problem in Florida Homes?

Florida waters aren't typically known for lead contamination, but that doesn't mean homes are risk-free. Houses built before the late 1980s are more likely to have plumbing systems made with materials that can add lead to drinking water. While many municipal systems use corrosion control methods, these measures aren't necessarily foolproof.

On top of that, private wells, which are common in some parts of Florida, don't have the same regulations and monitoring requirements applied. These variables mean lead can still be a concern in Florida homes, especially in older properties or those with outdated plumbing fixtures.

Does a Water Softener or Filter Remove Lead?

Not all water treatment systems can remove lead. For example, standard water softeners are designed to reduce hardness by eliminating calcium and magnesium. They may remove trace amounts of certain metals, but they are not reliable for lead removal. Some filtration systems, however, are specifically designed to target lead. Activated carbon filters are effective for point-of-use applications, such as kitchen taps. However, reverse osmosis (RO) systems are even better, as they remove a wide range of contaminants, including lead, at a very fine level.

Systems should be independently tested and certified for lead removal, for without proper certification, a filter may improve taste but still leave harmful contaminants behind.

The Best Long-Term Solution for Lead-Free Water

Lead-contaminated water should be addressed not just for the present, but also for the long term. Short-term strategies include flushing your taps before use, using cold water for cooking and drinking, and installing certified filters to reduce exposure. However, an effective long-term solution is to eliminate the source of contamination:

• Replace lead service lines.
• Upgrade old plumbing.
• Install a combination of whole-house and point-of-use filtration systems.
• Regularly test the water.

Lead in drinking water is a serious issue, but it can be managed with the right information and solutions.
