Karst aquifers and water resource contamination in Haiti

Abstract Shallow alluvial and karst aquifers widespread inadequate sanitation practices combine to impact water resources in Haiti. The vulnerability of is complicated by complex cultural, ecological, geological, hydrological, hydrogeological considerations. Roughly 84% the rocks exposed Haiti consist calcareous alluvium. These lithologies serve as an efficient reservoir transport mechanism for water-borne pathogens, which negatively health many Haitians. Data from 9,837 points indicate that 75% sources Centre, 55% Nord (North), 12% Ouest (West) departments are considered unsafe or high risk based on World Health Organization standards. Inadequate and, some cases, improper siting installation pit latrines contribute poor quality. Numerous safe-water intervention technologies exist effective at removing pathogens contaminate sources; however, Haitians lack means obtain these solutions. Future regional precipitation climate trends will have important implications selecting appropriate interventions. Additional efforts collect compile quality data needed better understand country-wide contamination patterns.
