How Old Is Webb City's Housing Stock?
With 45% 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
A citywide median of 1998 for construction says little about any single address in Webb City. Homes built before 1986, when federal amendments restricted the lead content allowed in new pipe, solder and flux, may contain plumbing materials with more lead, and later renovations may have replaced them. An inspection of the plumbing can identify the materials, and sending a tap water sample to an accredited laboratory measures lead.
A significant portion of Webb City's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Protecting Children from Lead in Webb City
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
