What is being done to ensure the safety of our drinking water?
Arlington County Department of Environmental Services works with the Washington Aqueduct Division and our partners at DC Water and Sewer Authority and the City of Falls Church to ensure that the treatment plants are producing water in compliance with all existing regulations and that we are positioned to address forthcoming regulations. A significant improvement in water quality was the conversion to disinfection with Chloramines starting in 2000. This change resulted in significant reductions in disinfection by-product formation as compared to our previous practice of treating with free chlorine all year.
