I bet that is some pure water though
I would drink it before tap water.
Even then, it's surprising that there have been a bunch of chemicals found in samples from glaciers. Here's a couple paragraphs about fluoride compounds.
My friend worked at an aluminum plant for years. He said that they had a chimney that they'd open to release fluoride gasses out into the air. Countries like China and India are even worse about that.

xic chemicals found at antarctica
Toxic chemicals have been found in Antarctica, specifically fluorinated forever chemicals, also known as PFASs (per- and polyfluoroalkyl substances). These chemicals are used in various industrial products, such as non-stick cookware, food packaging, and clothing. They can harm wildlife and humans if ingested or inhaled.
Research suggests that these chemicals are reaching Antarctica through the release of volatile precursors into the atmosphere at industrial manufacturing sites. These precursors waft in the global atmosphere until they eventually degrade in the presence of sunlight to form the more persistent PFASs.
Studies have found that PFASs have increased markedly in the remote environment of Antarctica in recent decades. For example, a study published in 2022 found that seven out of nine snow samples taken on land in Antarctica contained PFASs. Another study published in 2024 found that levels of PFASs in Antarctica have been increasing, with scientists believing that CFC-replacements could be among the likely sources."
