Dissolved Oxygen, also known as Oxygen Saturation, is a measure of the amount of gaseous oxygen that is present in natural bodies of water – ponds, lakes, rivers, streams – as well as stormwater runoff, wastewater, ﬁsh farms and aquariums. It gives an indication of the health of the water and its ability to sustain a balanced aquatic ecosystem. DO levels are also important in drinking water and many other industries.*
*Our drinking water tastes better with high DO levels; however, industry prefers low DO in its water supply as the oxygen promotes corrosion in piping.
