Landfills in California, including DUNNIGAN, must address key environmental factors such as landfill gas generation and methane leakage, which contribute to greenhouse gas emissions. Leachate management is critical to prevent groundwater contamination, especially in areas with agricultural land use. Proximity to communities and traffic from waste hauling also require careful planning to minimize odors, noise, and air quality impacts.
