  • Biological Oxygen Demand (BOD) is one of the most widely used water quality indicators, measuring the degree of organic pollution of water — an umbrella proxy of river health;
  • Nitrogen (nitrate-nitrite) is used to capture water pollution from excessive nutrient loading in water bodies, which is primarily caused by agricultural run-off and untreated wastewater, and which can be harmful to both human and ecosystem health in sufficient concentrations; and
  • Electrical Conductivity (EC) is used as a proxy for salinity balance and changes to pH levels as saline water can be disastrous for both agriculture and human health, particularly of young children.
