Intensive land development as a result of the rapidly growing tourism industry in the "Riviera Maya" region of the Yucatan Peninsula, Mexico may result in contamination of groundwater resources that eventually discharge into Caribbean coastal ecosystems. We deployed two types of passive sampling devices into groundwater flowing through cave systems below two communities to evaluate concentrations of contaminants and to indicate the possible sources. Pharmaceuticals and personal care products accumulated in the samplers could only have originated from domestic sewage. PAHs indicated contamination by runoff from highways and other impermeable surfaces and chlorophenoxy herbicides accumulated in samplers deployed near a golf course indicated that pesticide applications to turf are a source of contamination. Prevention and mitigation measures are needed to ensure that expanding development does not impact the marine environment and human health, thus damaging the tourism-based economy of the region.
由于墨西哥尤卡坦半岛“里维埃拉玛雅”地区旅游业的迅速发展，密集的土地开发可能导致地下水资源受到污染，最终排入加勒比沿海生态系统。我们在两个社区下面的洞穴系统中部署了两种类型的被动采样设备，以评估污染物的浓度，并指示可能的来源。在采样器中积累的药物和个人护理产品只能来自家庭污水。多环芳烃表明，污染来自高速公路和其他不透水表面的径流，而在高尔夫球场附近部署的采样器中积累的氯苯氧酸除草剂表明，草坪农药的使用是污染的一个来源。需要采取预防和缓解措施，以确保不断扩大的发展不会影响海洋环境和人类健康，从而破坏该地区以旅游业为基础的经济。
