Water from rivers, lakes, ponds and streams can contain bacteria, parasites, viruses and possibly other contaminants. To make surface water fit to drink, treatment is required. Remember, we use our drinking water in many different ways.the most dangerous contamination in water is invisible to the naked eye. Microscopic impurities like bacteria, viruses and parasites that contaminate water cannot be smelled, tasted or even seen. Hence even if your water is clear, it doesn't mean it is safe to drink.
