A meter is used to measure total dissolved solids. Turbidity Clarity of the water, or the amount of suspended particles in the waterbody. In addition to blocking out the light required by aquatic plants and animals, suspended sediment can carry nutrients and pesticides throughout the system. Turbidity is measured with a meter, turbidity tube or Colorimetrically. The amount of nitrates in the water indicate organic enrichment and consequent health of a waterway.
High levels can lead to increased algal growth.
Phosphates Phosphorous in the water primarily comes from human and animal faeces runoff from rural and urban areas. This parameter indicates the nutrient status and consequent health of the waterbody. High levels may stimulate algal blooms, large swings in DO and imbalances in aquatic communities. Temperature Indicates the approximate temperature of the water which varies with depth season and time of day. Many of the physical, chemical and biological characteristics of a stream are directly affected by this parameter.
