Plum Point Spring (mold warning)

Visited this spring in August of 2023. Indeed, spring was gushing clear cold water. However, a week later I noticed mold growing in the water bottle that was filled with this water. I deep cleaned this water bottle with a strong enzyme cleaner, apple cider vinegar & hot water, and warm water & soap multiple times. I waited a few days and filled this water bottle again with the water from Plum Point spring and noticed mold growing again. I tossed out all the water from Plum Point Spring and have been drinking other water. Since drinking other water, I’ve noticed no signs of mold.

Not sure what’s going on here with the water. Could be bacteria in the pipe or bacteria in the water. I definitely recommend someone test this water!
