A turbidity reading of 0.25 NTU is compliant with the turbidity standard.

Explanation:
Turbidity compliance for treated water is based on keeping water clear enough after treatment. The standard requires finished water turbidity to be no more than 0.3 NTU in at least 95% of samples each month, and no single sample may exceed 1 NTU. A reading of 0.25 NTU is below the 0.3 NTU threshold and well under the 1 NTU cap, so it meets the standard for that measurement. Turbidity measurements are taken on the finished water after filtration to reflect how well the treatment process is performing. So, a 0.25 NTU reading is compliant.
