Housing Age Profile
Because the majority of Bellmore's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1952 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Bellmore 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 Bellmore

Bellmore: Lead Risk & Vulnerable Populations
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 Bellmore, where 89% 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.

Bellmore: Flood History & Water Damage Risk
Unlike communities where NFIP data shows minimal flood history, Bellmore's record documents 2217 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.
Bellmore has a significant flood history with 2,217 FEMA flood insurance claims on record, averaging $35,959 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.
