Gradyville Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Gradyville, where the median build year is 2006, the housing stock falls broadly on the newer side of that threshold — a distribution that moderates aggregate plumbing-era risk compared to older housing markets.
Most homes in Gradyville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Gradyville: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If aggregate samples sit below the EPA action level and just 28% of Gradyville's inventory comes from the pre-rule era, systemic lead is not a dominant local concern. The aggregate still cannot tell a homeowner what is actually flowing from a specific faucet on a specific morning, which is why an in-home draw exists as a separate measurement at the household tier.
