Beyond these two main methods, there are also alternative measures of turbidity measurement that are used to complement data from more direct methods such as the use of turbidimeters. These include indirect optical measurement through various techniques such as spectral absorption, light scattering, buoyancy tests and ultraviolet measurement.
To summarize, there are several methods to measure turbidity in water, from the most direct such as the use of turbidimeters, to the most indirect such as the Jackson-Turck scale and indirect optical measurement. The choice of the most appropriate method depends on the objectives of the monitoring and the preferences of those responsible for water resources management. Whatever method is chosen, it is important to remember that measuring turbidity is an important way to determine the quality of water resources and to take action to prevent pollution.
