Answer:

The concentration of impurities in the filtered water is 33 ppm.

Explanation:

Initially, the concentration of impurities is 330 ppm. If the filter removes 90% of impurities, then only 10% of the original impurities remain in the filtered water. Therefore, their concentration will be 10% of 330 ppm, that is, 33 ppm.
