Housing & Infrastructure in Grand Junction
With 50% 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, Grand Junction is predominantly an older city - a median build year of 1987 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Grand Junction 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 Grand Junction Homeowners
Placing remediation in the context of Grand Junction's property market, the equity share is low - most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in Grand Junction are relatively low compared to home values. The $1,486–$3,043 estimated range is a small fraction of median property value. Home values are 5% below the Colorado average.
Lead Exposure Risk for Children in Grand Junction
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 50% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Grand Junction.

Historical NFIP Claim Context in Grand Junction
Historical NFIP data for Grand Junction contains 42 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $15,084. Among ZIP codes with claim records, 50% 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>$2,229</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.
