What is Safe Drinking Water?

Standards for Safe Drinking Water
Fluoride: For drinking purposes, water should be tested for fluoride ion concentration. Its deficiency in drinking water is harmful to humans and causes health issues such as tooth decay etc.
Lead: Drinking water gets contaminated with lead when lead pipes are used for transportation of water. Lead can damage kidney, liver, reproductive system etc.
Sulphate: Excessive sulphate (>500ppm) in drinking water causes laxative effect, otherwise at moderate levels it is harmless.
Nitrate: The maximum limit of nitrate in drinking water is 50 ppm. Excess nitrate in drinking water can cause disease such as “blue baby” syndrome.
