Answer:

Low levels of fecal coliform

Explanation:

The pH (hydrogen potential) of a water considered <u>pure</u> 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.
