Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile

Housing age is a practical proxy for plumbing risk because federal standards changed in 1986, when lead solder was banned from new residential construction, and again earlier — before 1970, lead pipes were themselves commonly installed. Tooele's median build year of 1993 sits in the range where both pre- and post-1986 homes are well represented. The bar chart above reflects that mixed picture: the distribution captures pockets of older housing alongside more recent development, and those pockets carry real lead risk potential at the individual property level.

16%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (16%) 1970–1986 (19%) Post-1986 (65%)

Most homes in Tooele were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Tooele Homeowners

In Tooele, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.

Median Home Value
$383,300
Est. Remediation
$1,600
Remediation as % of home value 0.4%

Remediation costs in Tooele are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 2% below the Utah average.

Lead Exposure Risk for Children in Tooele

35%
Homes Built Before 1986
0.0026
mg/L Avg Lead (Limit: 0.015)

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 35% of the Tooele 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.

Flood & Climate Risk in Tooele

Flood risk in Tooele occupies the middle ground: 4 NFIP claims and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.

ZIPs in FEMA Flood Zones

Tooele has a moderate flood history with 4 FEMA claims averaging $13,197 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>$1,600</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.
