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

浅层冲积层和喀斯特含水层以及普遍存在的卫生措施不足共同影响了海地的水资源。含水层的脆弱性因复杂的文化、生态、地质、水文和水文地质因素而变得复杂。海地大约 84% 的岩石由钙质岩石和冲积层组成。这些岩性是水传播病原体的有效储层和运输机制，对许多海地人的健康产生负面影响。来自 9,837 个取水点的数据表明，根据世界卫生组织的标准，中部 75% 的水源、北部（北部）部门的 55% 和西部（西部）部门的 12% 被认为是不安全或高风险的。卫生设施不足，在某些情况下，坑式厕所的选址和安装不当会导致水质变差。存在许多安全水干预技术，并能有效去除污染水源的病原体；然而，许多海地人缺乏获得这些解决方案的手段。未来的区域降水和气候趋势将对选择合适的水源和安全水干预措施产生重要影响。需要进一步努力收集和汇编区域水质数据，以更好地了解全国范围的污染趋势和模式。
