Municipal and industrial trash is frequently disposed of in solid waste dumps or landfills. However, these dump sites have a substantial impact on the quality and availability of groundwater, which is essential for supporting ecosystems and providing for human requirements in terms of water. In this article, the effect of solid waste disposal yards on groundwater is examined, along with any possible repercussions. Leachate, a fluid that introduces contaminants into the groundwater, can occur as a result of poor trash compaction, inadequate liners or barriers, or incorrect management of dumping yards. Although leachate composition varies, it frequently contains toxic materials, organic contaminants, and heavy metals. Since individuals might be exposed to these toxins through irrigation and drinking water, groundwater contamination poses serious dangers to the public’s health. Ecosystems and biodiversity are also disrupted, and rehabilitation attempts may be financially costly. Proper landfill site selection, the installation of liners and leachate collecting systems, as well as routine groundwater monitoring, are essential to reducing the impact. In order to avoid the negative effects of solid waste disposal yards on groundwater resources, effective waste management practises are crucial.
