Bottled Water Purity: Is Fish Urine Contamination a Concern?

The answer to this question is: no

Bottled water is typically sourced from underground aquifers or springs, which are naturally filtered and free from contaminants. Fish pee is found in the ocean or other bodies of water where fish live. These two water sources are completely separate and do not mix. Therefore, it is not possible for fish pee to get into bottled water.
