Olympia 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
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Olympia's median build year of 1995 puts most of its residential stock on the newer side of that boundary — a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Olympia were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Olympia
Because property values in Olympia comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Olympia are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 4% below the Kentucky average.
Olympia: 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.
19% of housing in Olympia predates the federal action against lead solder — a contained share — and aggregate readings stay beneath the regulatory benchmark. Lead therefore sits in a quiet position on the local water-quality picture, with single-home draws as the standard tool for confirming any one address.

What You Can Do in Olympia
- 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.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
