Likely Pipe Material

With 55% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile

While newer cities carry lower aggregate plumbing risk from lead-era construction, Mason sits firmly in the older category. The median build year of 1988 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing - and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.

Over half of homes in Mason were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mason: Remediation Cost in Perspective

The Mason equity share sits above the low tier but short of the range where remediation becomes a heavy financial burden - the cost-to-value ratio is moderate, and deliberate planning is the key practical lever for most homeowners.

Median Home Value
$182,700
Est. Remediation
$2,200
Remediation as % of home value 1.2%

Remediation costs are moderate relative to home values in Mason. The estimated $1,200–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 21% below the Wisconsin average.

Protecting Children from Lead in Mason

55%
Homes Built Before 1986

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.

Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 55% of Mason stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

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.
