How Old Is Manasquan's Housing Stock?
With 66% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Manasquan's median build year of 1963 places it squarely in that category.
Over half of homes in Manasquan were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Manasquan: Remediation Cost in Perspective
Across Manasquan, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Manasquan 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 76% above the New Jersey average.
Protecting Children from Lead in Manasquan
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.
Routinely in Manasquan, where 66% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Climate-Related Water Risk for Manasquan
Unlike communities where NFIP data shows minimal flood history, Manasquan's record documents 2241 claims and 100% of ZIP codes inside FEMA flood zones — a combination that moves flood-related water quality risk from the background into the foreground of any complete local water assessment. Flooding can overwhelm treatment capacity, contaminate wells, and trigger distribution backflow; at this level of exposure, those mechanisms have likely been activated during significant flood events.
Manasquan has a significant flood history with 2,241 FEMA flood insurance claims on record, averaging $46,015 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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.
