How Old Is Alton's Housing Stock?
With 53% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Viewed through the lens of construction era, Alton is predominantly an older city - a median build year of 1986 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Alton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Alton: Remediation Cost in Perspective
When estimated remediation is placed alongside median property values in Alton, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Alton are relatively low compared to home values. The $1,100–$4,100 estimated range is a small fraction of median property value. Home values are 9% below the New Hampshire average.
Protecting Children from Lead in Alton
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 Lead and Copper Rule oversight at the utility tier, citywide samples in Alton have moved beyond 0.015 mg/L - and 53% of local stock predates the ban on solder containing lead. The high-pre-1986 share combined with above-action samples leaves an in-home test and certified filtration via retailer networks as the household-tier tools, available for families with kids or pregnant residents. Periodic retesting after plumbing work or extended stagnation captures changes the initial draw cannot.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
