1.	Turbidity of raw water is a measure of ___________(a) Suspended solids(b) Acidity of water(c) B.O.D(d) AnywhereI have been asked this question during an internship interview.The doubt is from Water Supply, Electrical and Road Work in section Rules and Methods of Measurement of Civil Engineering Drawing
Answer» Right answer is (a) Suspended solids To explain I would say: The definition of Turbidity is the cloudiness or haziness of a FLUID caused by suspended solids that are USUALLY invisible to the naked eye. The measurement of Turbidity is an important test when trying to determine the quality of water. It is an aggregate optical property of the water and does not identify INDIVIDUAL SUBSTANCES; it just says SOMETHING is there.
