Turbidity is the measure of water clarity. The more suspended solids in the water, the cloudier it becomes. Here on the west coast of Canada, most of our drinking water is rain water. When it runs off the hills, it picks up sediment and it flows into the reservoirs. This murkiness not only affects the waters “drinkability”, the suspended particles absorb heat from the sun and warm the water. The warmer water holds less oxygen and is less healthy to drink.
When the water becomes cloudy, extra chlorine is added to kill any organisms attached to the particulate matter. When the chlorine comes in contact with organic matter in the water, a chemical reaction takes place which creates toxic chlorine by-products that you really don’t want to be drinking.… Read the rest
