In reporting the water quality, turbidity is expressed in which unit?

Explanation:
Turbidity measures how cloudy water is from suspended particles, not the amount of dissolved substances. It’s determined by how much light is scattered by those particles using a nephelometer, and the result is recorded in nephelometric turbidity units (NTU). This unit directly reflects the cloudiness caused by particulates, which is why NTU is used for reporting turbidity. The other options describe concentration (mg/L, ppm) or pH, which relate to different water quality aspects, not turbidity.
