A wave of change rising from EPA’s National Nutrient Strategy may mean profound consequences for Florida’s wastewater utilities. Florida’s water reclamation plants already operate within a complex system of water quality regulations that are among the most stringent in the world. If the numeric nutrient criteria now being considered by EPA and FDEP are implemented in the state’s water quality regulations, all Florida wastewater facilities that discharge reclaimed water to rivers, streams, and lakes may be required to meet new, very low limits on the discharge of nitrogen and phosphorus. This article provides an overview of the proposed water quality criteria that would be imposed under EPA’s reference stream approach, the types of treatment technologies required to meet these effluent criteria, and cost implications.
