Housing Age Profile
What does a median build year of 1964 mean for water safety in Hazlet? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Hazlet 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 Hazlet Homeowners
In Hazlet, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Hazlet 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 6% below the New Jersey average.
Lead Exposure Risk for Children in Hazlet
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 86% of the Hazlet inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Flood & Climate Risk in Hazlet
Flood exposure in Hazlet is meaningful by NFIP measures — 99 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Hazlet has a moderate flood history with 99 FEMA claims averaging $15,156 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>$3,000</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.
