To most people not professionally involved in water quality issues, water is either drinkable (technically potable) or contains potentially harmful or toxic substances (suffering from water pollution). However, the vast majority of surface water on the planet is neither potable nor toxic. This remains true even if we eliminate from consideration the more than 97% of the earth's water found in the oceans (sea water)—too salty to drink. Another general perception of water quality is that of a simple property that tells whether water is polluted or not. In fact, water quality is a very complex subject, in part because water is a complex medium intrinsically tied to the ecology of the planet.
Overview
Interest by individuals and volunteer groups in making local water quality observations is high, and an understanding of the basic chemistry of many water quality parameters is an essential first step to making good measurements. Most citizens harbor great concern over the purity of their drinking water, but there is far more to water quality than water treatment for human consumption.
