Water Pollution & Effluents evaluates how a company prevents, treats, monitors and discloses the quality of wastewater and process discharges that leave its sites and supply chain. It encompasses:

• mapping of point-source (e.g., process drains, cooling-tower blow-down, sanitary effluent) and non-point-source releases (storm-water runoff, leachate) to surface water, groundwater or municipal systems;
• identification and quantification of pollutants - nutrients (N, P), heavy metals, solvents, priority organic compounds, endocrine-disrupting chemicals, microplastics, pathogens, salinity and thermal loads;
• on-site and off-site treatment technologies (physico-chemical, biological, advanced oxidation, membrane, zero-liquid-discharge) and spill-prevention measures;
• monitoring, sampling and reporting against regulatory limits (e.g., EU Water Framework Directive, U.S. NPDES), voluntary standards (IFC EHS Guidelines) and frameworks such as GRI 303-4/5, EU ESRS E2/E3 and SDG 6;
• disclosure of key metrics - volume of effluent discharged, mass of pollutants, compliance incidents - and continuous-improvement targets to protect freshwater and marine ecosystems.
