What are the types of Class I wells?
Class I wells are classified as either hazardous, non-hazardous industrial, municipal, or radioactive depending on the characteristics of the fluid injected. The construction, permitting, operating, and monitoring requirements are more stringent for Class I hazardous wells than for the other types of injection wells. The four types of Class I wells are: • Hazardous Waste Disposal Wells. These wells inject hazardous waste, as defined by the Resource Conservation and Recovery Act ( RCRA). Hazardous waste disposal wells are stringently regulated by the Safe Drinking Water Act and RCRA. Most Class I hazardous wells are located at industrial facilities. Only a few Class I wells are at commercial operations that can accept hazardous waste generated offsite. Class I hazardous waste wells operate in 10 states with the majority in Texas and Louisiana. Approximately 22 percent of Class I wells are hazardous waste disposal wells. Animation: Protective Aspects of Hazardous Waste Wells A five minut
