Housing & Infrastructure in Havre
With 82% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Havre's median build year of 1978 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Havre were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Havre Homeowners
Property value and cost data for Havre produce a moderate remediation-share classification — a level where advance financial planning has real practical value and the commitment is realistic for most homeowners who approach it deliberately.
Remediation costs are moderate relative to home values in Havre. The estimated $1,900–$4,800 range is manageable for most homeowners but still worth budgeting for. Home values are 32% below the Montana average.
Lead Exposure Risk for Children in Havre
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Havre have approached or crossed the regulatory action level on multiple occasions. Combined with 82% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Flood & Climate Risk in Havre
100% of ZIP codes in Havre are mapped into FEMA-designated flood zones, and the NFIP records 16 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Havre has a moderate flood history with 16 FEMA claims averaging $3,416 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>$3,000</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.
