This landfill leachate issue is significantly exacerbated by the increasing occurrence of overheating, where internal temperatures exceed safe limits, thereby accelerating chemical reactions and amplifying leachate production within landfills. A comprehensive investigation by Bloomberg in 2025, focusing on sites like Chiquita Canyon Landfill in Los Angeles County, has detailed how these elevated temperatures, often exceeding 200\u00b0F (93\u00b0C) create a vicious cycle of heat and accelerated waste decomposition.
