Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Keansburg's Housing Stock?
With 83% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Decades of residential development in Keansburg took place before the two main regulatory milestones that reduced plumbing-era lead risk: the phase-out of lead pipes before 1970, and the federal ban on lead solder in 1986. With a median build year of 1969, the housing stock here is anchored in that earlier period. The distinction between pre-1970 and 1970-to-1986 construction matters: the oldest homes may have lead pipes in the service line and lead solder in the copper joints, while the 1970-to-1986 tier still carries the solder risk even after lead pipes became less common. Together, these two risk layers affect a majority of the residential properties in the city — a fact the aggregate water quality data doesn't directly reveal.
Over half of homes in Keansburg were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Keansburg: Remediation Cost in Perspective
Across the Keansburg housing market, the estimated remediation share lands in a middle tier — not a minor footnote, but not a prohibitive burden either; the cost-to-value ratio reflects a moderate equity commitment, one that sits above routine maintenance territory and warrants a dedicated line in the household budget.
Remediation costs are moderate relative to home values in Keansburg. The estimated $2,550–$5,400 range is manageable for most homeowners but still worth budgeting for. Home values are 36% below the New Jersey average.
Protecting Children from Lead in Keansburg
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.
Locally, 83% of Keansburg homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Climate-Related Water Risk for Keansburg
Over the multi-decade span covered by the National Flood Insurance Program, Keansburg has accumulated 1366 flood claims — a total that reflects a community where significant flooding is a recurring, documented feature of the local environment. That history has direct relevance to water quality. Each major flood event activates contamination pathways that are absent or dormant during dry conditions: treatment plants handling floodwater-saturated intake face sharply elevated contaminant loads; private wells in low-lying FEMA-designated zones — which cover 100% of local ZIP codes — can be infiltrated by surface runoff carrying bacteria, sediment, and chemical residue; distribution systems under pressure during flooding can experience backflow that draws untreated water into the supply.
Keansburg has a significant flood history with 1,366 FEMA flood insurance claims on record, averaging $34,285 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>$3,900</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.
