How Old Is Mars Hill's Housing Stock?
With 51% 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
Heavily weighted toward older construction, Mars Hill's housing stock carries a median build year of 1984. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Mars Hill were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mars Hill: Remediation Cost in Perspective
Equity impact data for Mars Hill lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Mars Hill are relatively low compared to home values. The $1,800–$4,800 estimated range is a small fraction of median property value. Home values are 23% above the North Carolina average.
Protecting Children from Lead in Mars Hill
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 51% of the Mars Hill inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Climate-Related Water Risk for Mars Hill
Within the NFIP's national dataset, Mars Hill falls in moderate-exposure territory — 11 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Mars Hill has a moderate flood history with 11 FEMA claims averaging $54,576 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,900</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
