Question

The chloride content in the water for community supply should not be more than

Answer 1

Answer is - 250 ppm

Public drinking water standards require that chloride level in water should not exceed 250 mg/L. The EPA requires that treated tap water should have a detectable level of chlorine to prevent contamination. It recommends a maximum concentration of 250 mg/1 for chloride ions and 250 mg/1 for sulfate ions. The level of chlorine that is allowed by the EPA does not pose any known health risk.
