Sandy shows moderate tap water quality for UT - some areas carry documented EPA violations while others meet standards without issues.

Data: EPA SDWIS

Overview

We track home safety data for 6 ZIP codes in Sandy, Utah (population ~110,785), covering 8 community water systems serving approximately 608,994 people region-wide. The EPA snapshots used for this build directly map water systems to 4 of 6 ZIP codes.

4 of 4 ZIP codes with a reported violation count in the available EPA record (100%) have recorded EPA violations. The available record reports no health-based violations for this measured scope.

Home Safety Score

Average Home Safety Score for Sandy: C (57/100)

Model 4.0.0 uses four measured components across three equally weighted domains. If a required domain is unavailable, no score is published:

Factor	What It Measures
Water Quality	EPA violations and compliance history
PFAS MCL Screen	UCMR 5 testing against the covered federal MCLs
Radon Risk	EPA radon zone classification
Annual AQI	EPA AirData county-year median with at least 90 observed days

Water Sources

Sandy water systems draw from: Groundwater, Surface water.

Lead & Copper

• Average lead level (90th percentile): 0.0058 mg/L (EPA action level: 0.015 mg/L)
• 0 of 4 ZIP codes with known status exceed the EPA lead action level

Radon Risk

Dominant radon zone: Zone 2 (Moderate Risk)

• Zone 1 (High): 0 ZIP codes
• Zone 2 (Moderate): 6 ZIP codes
• Zone 3 (Low): 0 ZIP codes

The EPA recommends testing homes in Zone 1 and Zone 2 areas for radon.

Housing Age Profile

Sandy's housing stock is predominantly older, with a median build year of 1982 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here - a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (6%) 1970–1986 (53%) Post-1986 (41%)

Over half of homes in Sandy 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 Sandy Homeowners

When remediation costs are measured against Sandy home values, the resulting ratio is in the low tier - addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.

Median Home Value

$643,800

Est. Remediation

$1,900

Remediation as % of home value 0.3%

Remediation costs in Sandy are relatively low compared to home values. The $950–$3,100 estimated range is a small fraction of median property value. Home values are 65% above the Utah average.

Lead Exposure Risk for Children in Sandy

59%

Homes Built Before 1986

0.0058

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.

59% of Sandy housing dates to the pre-rule era, alongside aggregate readings hovering at the federal action mark - household-level confirmation through a draw-test kit fits the local picture.

Historical NFIP Claim Context in Sandy

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

0%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Sandy contains 12 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,411. 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>$1,900</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.
