Question

Which of the following is an indicator of a good water quality.

Ph higher then 9.0
Low levels of fecal coliform
All the above

Answer 1

Ph in ground water ranges from 6.5 to 8.5 any higher would be low-quality so the answer would most clearly be Low levels of fecal coliform.

Answer 2

Low levels of fecal coliform

Step-by-step explanation:

The pH (hydrogen potential) of a water considered pure is 7. Since the ideal pH for consumption is between 6.5 and 8.5 (neither too alkaline nor too acidic), so the first statement is false.

A low level of fecal coliforms indicates lower risk of contamination by various types of microorganism, allowing water to be consumed. So the second statement is true.
