Hasn the EPA lowered regulatory limits for water quality after some ISR operations?
The EPA groundwater standards include what is referred to as an alternate concentration limit (ACL), if all practical efforts to meet the baseline condition of an element are unsuccessful. ACLs apply only to water in the mine area, which is already high in minerals and exempt from human use. The altered concentration limits are not applied to drinking water, and still provide an equivalent protection of human health and the environment.
