Wastewater discharge refers to the intentional release of treated or untreated wastewater from point or non-point sources into receiving environments such as rivers, lakes, coastal waters, or groundwater. As a research topic, it encompasses the characterization of effluent composition (e.g., nutrients, organic load, pathogens, micropollutants), hydrodynamic and dispersion processes, and the assessment of impacts on physicochemical water quality, ecological status, and human health. It also includes development and evaluation of regulatory standards, discharge permits, and best available technologies to minimize pollutant loads, as well as modeling and monitoring strategies to quantify emissions and their environmental fate.
The Florida Department of Environmental Protection has issued a draft proposal that would allow nearly 500,000 gallons of wastewater daily at Blue Origin's Merritt Island facilities that would affect the Indian River Lagoon.
