How Old Is Marshville's Housing Stock?
With 60% 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
What does a median build year of 1972 mean for water safety in Marshville? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Marshville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Marshville: Remediation Cost in Perspective
In Marshville, the equity share of documented remediation is meaningful enough to move the household financial perspective from routine maintenance into deliberate budgeting territory — the cost-to-value ratio is moderate, and most homeowners benefit from mapping the full scope against available budgets before committing.
Remediation costs are moderate relative to home values in Marshville. The estimated $2,800–$5,600 range is manageable for most homeowners but still worth budgeting for. Home values are 2% below the North Carolina average.
Protecting Children from Lead in Marshville
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.
Older interior plumbing dominates the Marshville inventory at 60%, and citywide utility samples have crossed the federal action mark. Two independent indicators align here, raising lead to a household-level priority — particularly for families with kids.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
