Detalles de Calidad del Agua

Washington D.C.’s drinking water is supplied under United States’s national standards and monitored by local utilities and health authorities. The system draws primarily from a mix of surface and groundwater sources and uses chlorination, chloramination, ozonation, filtration, coagulation/flocculation, UV treatment before distribution through the city network. Taste and mineral content can vary by neighborhood and building age, and the water is typically hard with an estimated TDS around 350 mg/L. If you notice a chlorine or mineral taste, chilling the water or using an activated carbon filter can improve flavor without affecting safety.
