Turbidity is measured by nephelometric turbidity units (NTU) and can be initially.Noticed by the naked eye above approximately 4.0 NTU. However to ensure,,Effectiveness of disinfection turbidity should, be no more than 1 NTU and preferably.Much lower. Large well-run municipal, supplies should be able to achieve less than 0.5.NTU before disinfection at all times and should be able to average 0.2 NTU or less.Surface water (and groundwater under the infl uence of surface water) treatment systems.That achieve less than 0.3 NTU prior to disinfection will have demonstrated that.They have signifi cant barriers against pathogens that adsorb to particulate matter. Of.Particular importance is the fact that this will be a good indicator that they are removing.Chlorine-resistant pathogens such as Cryptosporidium.
