Water turbidity
Turbidity relates to the clarity of water. There are a number of ramifications of having turbid (cloudy/muddy) water, If water is very turbid less light is able to penetrate the waters surface preventing photosynthesis and effecting a number of under water organisms. Highly turbid waters can also effect the visibility of organisms effecting their eating habits and patterns. Turbidity is measured using a turbidity tube. A reading of 400 NTU indicates the water is very turbid whereas a reading of 0 NTU implies the water is clear.
Materials:
- Turbidity tube
- Water sample
Method:
1. Gradually pour the water sample into the turbidity tube, looking vertically down at the turbidity tube.
2. Stop pouring in the water sample when the black mark at the base of the turbidity tube is just visible.
3. Note the reading on the side of the tube to the point where the water has reached.
The turbidity of the water measured at Home bush was 10 NTU which was between the average of below 40 NTU.
