How Old Is Lagrange's Housing Stock?
With 59% 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, Lagrange is predominantly an older city — a median build year of 1972 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Lagrange were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lagrange: Remediation Cost in Perspective
At current valuations, Lagrange falls in the moderate remediation-share tier — a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Lagrange. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 15% above the Indiana average.
Protecting Children from Lead in Lagrange
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.
Practically, the structural drivers in Lagrange — 59% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark — make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

Climate-Related Water Risk for Lagrange
Flood exposure in Lagrange is meaningful by NFIP measures — 6 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Lagrange has a moderate flood history with 6 FEMA claims averaging $11,537 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>$2,400</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.

What You Can Do in Lagrange
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Surface Water Treatment Rule can reduce the most common contaminant found in Lagrange's water.
- Check your home's plumbing. With 59% of homes built before 1986, lead solder is a real possibility.
