How Old Is White's Housing Stock?
With 74% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile
Median construction year in White: 1956, set against the 1986 federal lead limits for new plumbing.
Over half of homes in White were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in White
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
74% of White homes were constructed before 1986, when federal law began limiting lead in pipes, solder and flux. Across the city's ZIP codes, water systems' 90th-percentile lead results average no less than 0.010 mg/L. That average can mix higher and lower systems, so it neither confirms nor rules out a problem at a single address; asking the utility how the home's service line is classified in its inventory is a practical next step.

What You Can Do in White
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. Choose a pitcher or under-sink filter certified to reduce the specific contaminants of concern.
- Check your home's plumbing. With 74% of homes built before 1986, lead solder is a real possibility.
