The upper Mbagathi River study has set key measurement parameters to be analysed.
In this post,we are going to breakdown and explain the key indicators of a clean river system.
These are the key water-quality indicators:
•Dissolved oxygen (DO)
The DO test measures the amount of oxygen
dissolved in the water.
Oxygen is essential for both plants and animals, but high levels in water can be
harmful to fish and other aquatic organisms.
Non-point-source pollution can decrease the amount of dissolved oxygen in water, which can be harmful to fish and other aquatic organisms.
The decomposition of leaf litter, grass clippings, sewage and runoff from livestock feedlots decreases DO readings.
Dissolved oxygen is measured in milligrams per liter (mg/L).
Expected levels: 4.0 to 12.0 mg/L
Aquatic organisms are dependent on certain
temperature ranges for optimal health.
Temperature affects many other parameters in water, including dissolved oxygen, types of…
