Question

Which statement is true regarding the Interim Enhanced Surface Water Treatment Rule for conventional or direct filtration?

A. Turbidity of the combined filter effluent must be less than 0.5 NTU in at least 90% of samples collected every month
B. The turbidity of the combined filter effluent must be less than or equal to 0.4 NTU in 90% of samples collected every month
C. Turbidity of the combined filter effluent must be less than or equal to 0.3 NTU in at least 95% of samples collected every month
D. The turbidity of the combined filter effluent must be less than 0.2 NTU in 95% of samples collected every month

Answer 1

The correct answer is A. Turbidity of the combined filter effluent must be less than 0.5 NTU in at least 90% of samples collected every month. Option a.

Step-by-step explanation:

The correct answer is A. Turbidity of the combined filter effluent must be less than 0.5 NTU in at least 90% of samples collected every month.

The Interim Enhanced Surface Water Treatment Rule for conventional or direct filtration sets a turbidity standard to ensure that the water is adequately treated. Turbidity refers to the cloudiness or haziness of the water caused by suspended particles. In this rule, the turbidity of the combined filter effluent must be less than 0.5 NTU (Nephelometric Turbidity Units) in at least 90% of samples collected every month.

This rule is important because turbidity is an indicator of how effectively the filtration process is removing particles and microorganisms from the water. By ensuring the turbidity is below the specified standard, the rule helps to ensure the safety and quality of the treated water.
