Although conditions vary by service area, Fairfield's water systems collectively show below-average compliance within CT - health-based violations are documented throughout the city, and the overall grade reflects a pattern rather than isolated incidents.

Data: EPA SDWIS

Overview

We track home safety data for 3 ZIP codes in Fairfield, Connecticut (population ~57,860), covering 1 community water system serving approximately 351,756 people region-wide. The EPA snapshots used for this build directly map water systems to 2 of 3 ZIP codes.

2 of 2 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 Fairfield: D (50/100)

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

Fairfield water systems draw from: Surface water.

Lead & Copper

• Average lead level (90th percentile): 0.0000 mg/L (EPA action level: 0.015 mg/L)
• 0 of 2 ZIP codes with known status exceed the EPA lead action level

Radon Risk

Dominant radon zone: Zone 1 (High Risk)

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

Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Fairfield's median build year of 1961 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (54%) 1970–1986 (29%) Post-1986 (17%)

Over half of homes in Fairfield were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Fairfield

While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Fairfield is notably favorable - the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.

Median Home Value

$827,200

Est. Remediation

$2,900

Remediation as % of home value 0.4%

Remediation costs in Fairfield are relatively low compared to home values. The $1,883–$4,067 estimated range is a small fraction of median property value. Home values are 103% above the Connecticut average.

Fairfield: Lead Risk & Vulnerable Populations

Homes Built Before 1986

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.

Even where utility-side monitoring meets Lead and Copper Rule requirements, the 83% pre-rule share in Fairfield keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Fairfield: NFIP Claim Records and Water-Quality Context

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

100%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Fairfield contains 2,199 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $28,757. Among ZIP codes with claim records, 100% 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>$2,900</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.
