Questions using turbidity
Problem 1
Which statement correctly uses turbidity in Watersheds, Water Quality & Sampling Limits?
- One illustrative result establishes every real condition and needs no further evidence.
- Clear-looking or filtered water is automatically safe to drink.
- One sample represents every place, season, and water-quality property.
- turbidity: A measure of water cloudiness associated with suspended material under a stated method.
Answer and explanation
turbidity: A measure of water cloudiness associated with suspended material under a stated method.
A measure of water cloudiness associated with suspended material under a stated method. A’s mean dissolved oxygen is 8 mg/L; B’s is 5 mg/L. A has lower recorded turbidity under the stated method. These indicators support different physical/ecological comparisons, but the small record does not identify every cause, represent all seasons, or certify either water as safe to drink.
