Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Bahama — it's the dominant profile. The median build year of 1983 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Bahama were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Bahama
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Bahama have approached or crossed the regulatory action level on multiple occasions. Combined with 50% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Climate-Related Water Risk for Bahama
Across the NFIP's long tracking period, Bahama shows 2 claims and 100% of ZIP codes within FEMA-designated flood zones — figures that place it in moderate flood exposure territory. At this level, the water-quality implications of flooding — contaminated wells, stressed treatment intake, distribution backflow — move from theoretical edge cases to genuine periodic risks, particularly during higher-severity events.
Bahama has a moderate flood history with 2 FEMA claims averaging $3,955 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>$1,200</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.
