How Old Is Cataldo's Housing Stock?
With 73% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Cataldo's median build year of 1974 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Cataldo were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cataldo: Remediation Cost in Perspective
Across Cataldo, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Cataldo are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 55% above the Idaho average.
Protecting Children from Lead in Cataldo
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 73% of the Cataldo 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 Cataldo
Measured across the NFIP's multi-decade tracking period, Cataldo shows a moderate flood record — 18 claims and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Cataldo has a moderate flood history with 18 FEMA claims averaging $17,364 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 Cataldo
- 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 Revised Total Coliform Rule can reduce the most common contaminant found in Cataldo's water.
- Check your home's plumbing. With 73% of homes built before 1986, lead solder is a real possibility.
