The aquifer flowing beneath the Yucatan Peninsula, México, is one of the largest in the world and is in direct contact with the surface through “cenotes” (sinkholes) that have been documented to be contaminated with various classes of pollutants. The objective of this study was to evaluate the environmental status of the Great Mayan Aquifer through a review of data published on pollution of the cenotes. Approximately 1000 known georeferenced cenotes on the Yucatan Peninsula were geographically located. A map was generated using the geographic information system software. High-resolution satellite images were processed to complement the “QuickMap Services” and the formatting service of the Environmental Systems Research Institute. From the literature, 173 cenotes were identified as being sampled for various pollutants, and of these, one or more classes of pollutants were detected in 160 (i.e., greater than 92%) of the cenotes. Pollutants reported to be present included bacteria and viruses of human origin, fecal sterols, polycyclic aromatic hydrocarbons (PAHs), pesticides, pharmaceuticals, illicit drugs and personal care products. From the review of the literature, only 13 cenotes were reported to be free of the target pollutants. From this study, it can be concluded that the aquifer system with the Yucatan Peninsula is vulnerable to contamination from pollutants originating from wastewater, as well as surface runoff and infiltration from urban and agricultural lands.

墨西哥尤卡坦半岛下方流动的含水层是世界上最大的含水层之一，通过已被证明被各种污染物污染的“天然井”（天坑）与地表直接接触。这项研究的目的是通过审查已发表的有关 cenotes 污染的数据来评估大玛雅含水层的环境状况。尤卡坦半岛上大约有 1000 个已知的地理参考天然井在地理位置上。使用地理信息系统软件生成地图。处理高分辨率卫星图像以补充“快速地图服务”和环境系统研究所的格式化服务。从文献中，确定了 173 个 cenotes 被采样用于各种污染物，其中，在 160 个（即大于 92%）的 cenotes 中检测到一种或多种污染物。据报道，存在的污染物包括人类来源的细菌和病毒、粪便甾醇、多环芳烃 (PAH)、杀虫剂、药物、非法药物和个人护理产品。从文献回顾来看，只有 13 个 cenotes 被报告为不含目标污染物。从这项研究可以得出结论，尤卡坦半岛的含水层系统容易受到来自废水的污染物以及城市和农业用地的地表径流和渗透的污染。多环芳烃 (PAH)、杀虫剂、药品、违禁药品和个人护理产品。从文献回顾来看，只有 13 个 cenotes 被报告为不含目标污染物。从这项研究可以得出结论，尤卡坦半岛的含水层系统容易受到来自废水的污染物以及城市和农业用地的地表径流和渗透的污染。多环芳烃 (PAH)、杀虫剂、药品、违禁药品和个人护理产品。从文献回顾来看，只有 13 个 cenotes 被报告为不含目标污染物。从这项研究可以得出结论，尤卡坦半岛的含水层系统容易受到来自废水的污染物以及城市和农业用地的地表径流和渗透的污染。
