North Haven's water safety record falls below average in CT - compliance violations span multiple service areas, and several systems have recorded exceedances that trigger federal notification requirements under the Safe Drinking Water Act.

Data: EPA SDWIS

Housing Age Profile

For residents trying to assess tap water risk in North Haven, the median build year of 1966 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (43%) 1970–1986 (35%) Post-1986 (22%)

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

North Haven: Remediation Cost in Perspective

In North Haven, documented water and safety issues can be addressed without making a meaningful dent in home equity - the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.

Median Home Value

$359,800

Est. Remediation

$3,000

Remediation as % of home value 0.8%

Remediation costs in North Haven are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 12% below the Connecticut average.

Protecting Children from Lead in North Haven

78%

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.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 78% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in North Haven.

Avg Reported Sum With Payment Data

100%

A/V Share of Claim-Record ZIPs

Historical NFIP data for North Haven contains 161 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,679. 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.
