Marco Island: 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.
Lead risk in Marco Island appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Marco Island: Flood History & Water Damage Risk
Marco Island carries a substantial flood exposure profile — 2023 claims filed over the program's long tracking window and 50% of ZIP codes within FEMA flood zones. For water quality, that exposure level means flooding has likely stressed local treatment and distribution infrastructure on multiple occasions, creating periodic windows of elevated contamination risk.
Marco Island has a significant flood history with 2,023 FEMA flood insurance claims on record, averaging $24,773 per claim. With 50% 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>$2,400</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.
