Public water monitoring in Bronxville shows a safety record well above the NY median - health-based violations are isolated exceptions rather than recurring patterns, the city's systems have stayed compliant across recent reporting cycles, and no cluster of recurring exceedances appears in any single service area.

Data: EPA SDWIS

Overview

We track home safety data for 1 ZIP code in Bronxville, New York (population ~21,946), covering 3 community water systems serving approximately 432,194 people region-wide. The EPA snapshots used for this build directly map water systems to 1 of 1 ZIP codes.

1 of 1 ZIP code 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 Bronxville: A (99/100)

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

Housing Age Profile

Reading the housing age data for Bronxville - median build year 1946 - the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints - a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.

Over half of homes in Bronxville 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 Bronxville

Setting Bronxville remediation figures against its property market, the resulting ratio sits comfortably in the low tier - a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Remediation as % of home value 0.6%

Remediation costs in Bronxville are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 37% above the New York average.

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 95% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Bronxville.

Bronxville: 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 Bronxville contains 444 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $46,293. 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>$3,000</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.
