Eureka Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Eureka's residential inventory spans multiple construction eras, with the median build year of 1994 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints - a plumbing practice banned that year - while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Eureka were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Eureka
Property equity in Eureka runs well ahead of estimated remediation costs - a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Eureka 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 0% above the Montana average.
Eureka: Lead Risk & Vulnerable Populations
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.
Wherever 38% of local housing was built before solder rules changed - as is the case in Eureka - a faucet-level sample closes the gap that aggregate utility data cannot.

Eureka: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Eureka contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $18,894. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
