How Old Is Whiteoak's Housing Stock?
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
For most of Whiteoak's housing stock, construction occurred after 1986 — when lead solder in plumbing was federally prohibited. The median build year of 1992 broadly reflects that newer profile.
Most homes in Whiteoak were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Whiteoak
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.
Even with citywide samples reading clean and just 16% of Whiteoak homes dating to the pre-rule era, individual-faucet conditions remain a separate question that aggregate utility data cannot resolve for one specific address. That gap is structural, not a function of severity.

What You Can Do in Whiteoak
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
