Key Contaminants Detected in Dublin
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Dublin'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
Buyers and renters in Dublin can ask a simple question of any home: was it built before 1986? The citywide median of 1995 will not answer it.
Most homes in Dublin were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
Dublin: Remediation Cost in Perspective
Measured against the median home value, the estimated cost of fixing the issues flagged for Dublin lands in the lowest of the three tiers this page uses.
Estimated remediation costs in Dublin can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 159% above the Ohio average.
Protecting Children from Lead in Dublin
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.
A tap test is the direct way to learn the lead level in a given Dublin home; 30% of local housing predates 1986.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Historical Flood-Claim Evidence for Dublin
Historical NFIP data for Dublin contains 26 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $19,825. Among ZIP codes with claim records, 50% 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 $500 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 Dublin
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Lead and Copper Rule Revisions, listed in the water-quality records for Dublin: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- 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. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
