How Old Is Powell'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
The year 1986 marks a critical threshold in residential plumbing safety: that's when the federal government banned lead solder from new construction, closing a major pathway for lead entering household drinking water via pipe joints. Powell's median build year of 1993 signals that most of the city's housing was built under the newer standard. The distribution above tells the full story - the post-1986 majority lowers aggregate risk, but the pre-1986 share still deserves scrutiny from anyone living in or purchasing an older home.
Most homes in Powell were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Powell: Remediation Cost in Perspective
Low proportionality - that's the Powell picture when remediation costs are placed against typical home equity.
Remediation costs in Powell are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 146% above the Ohio average.
Protecting Children from Lead in Powell
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.
Despite citywide averages reading cleanly under the federal action threshold, the way utilities pull samples - from a representative subset rather than door-to-door - leaves room for individual buildings with older interior lines to behave differently than the aggregate suggests. With only 25% of Powell stock predating the solder rule, that residual subset is small but real, and a draw-test kit gives the only direct read on what comes out of one faucet on a given morning.

Historical Flood-Claim Evidence for Powell
Historical NFIP data for Powell contains 32 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,636. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$3,000</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Powell
- 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.
