How Old Is Carbon's Housing Stock?
With 48% 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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1982 places Carbon in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
A significant portion of Carbon's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Carbon: Remediation Cost in Perspective
For most Carbon homeowners, estimated remediation represents a moderate equity share — manageable with planning.
Remediation costs are moderate relative to home values in Carbon. The estimated $800–$2,600 range is manageable for most homeowners but still worth budgeting for. Home values are 23% below the Indiana average.
Protecting Children from Lead in Carbon
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 48% of the Carbon inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Carbon
FEMA data shows 100% of Carbon's ZIP codes mapped into designated flood zones, paired with an NFIP record of 1 claim. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Carbon has a moderate flood history with 1 FEMA claims averaging $6,685 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>$1,600</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.
