Residents of Avenal, California, have filed a federal lawsuit against Waste Connections US Inc. and Madera Disposal Systems Inc., alleging that the Avenal Regional Landfill has caused severe health issues and degraded quality of life for about 43 residents and workers due to toxic gases and noxious odors. The landfill, situated just 500 feet from residential areas in a town with around 14,000 people, is accused of emitting harmful substances that have led to symptoms like headaches, breathing problems, and heart issues, prompting some residents to restrict outdoor activities.
