Key Contaminants Detected in Mason
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Mason'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
Although a small portion of Mason's homes predate 1986, the median build year of 1993 indicates the majority of the city's residential plumbing was installed after lead solder was banned - which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Mason were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Mason: Remediation Cost in Perspective
Equity impact data for Mason lands in the favorable tier - remediation claims a small slice of what properties here are worth.
Remediation costs in Mason are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 120% above the Ohio average.
Protecting Children from Lead in Mason
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.
In Mason, the older-stock footprint runs at 25% - a contained slice - and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.

Historical Flood-Claim Evidence for Mason
Historical NFIP data for Mason contains 20 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,971. Among ZIP codes with claim records, 0% 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>$2,200</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.
