Williston Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
A citywide median of 1997 for construction says little about any single address in Williston. 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.
Most homes in Williston were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Williston: Lead Risk & Vulnerable Populations
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.
