Regulations play a critical role in managing leachate to protect public health and the environment. In many countries, environmental agencies set guidelines and standards for landfill design, leachate collection, and treatment processes. For instance, the United States Environmental Protection Agency (EPA) enforces the Resource Conservation and Recovery Act (RCRA), which mandates specific criteria for hazardous waste management. These regulations ensure that leachate is properly contained and treated to minimize its toxicological impact.
