Natural hazards significantly impact drinking water availability
and reliability, posing challenges in accessing sufficient quality
and quantity. Understanding the connection between water access and
perceptions of psychological resilience (defined as how individuals
bounce back after facing a major trauma) can clarify its role in well-being
postdisaster. This study surveyed 208 older adults in Puerto Rico
(May–July 2021), aged 64–104 years, 65% of whom were
female, to explore this linkage following Hurricane Maria. Results
show a strong preference for bottled water with 86% of participants
using it as a drinking source. Municipal tap water is the second most
preferred at 71%, while well water is the least favored, used by less
than 4%. A gender-specific effect was found in the association between
municipal tap water consumption and psychological resilience, where
municipal tap water consumption was associated with higher psychological
resilience only among women. The findings suggest that although bottled
water is the preferred choice, municipal tap water use is positively
associated with psychological resilience among women postdisaster.
Research is needed to replicate these findings to attempt to determine
their consistency in other similar contexts and identify underlying
reasons and future implications for disaster response and preparedness.
