Review Summary
The Gray Bearded Green Beret, (a sort of authority in his field) is demonstrating how to use the Grayl GeoPress to purify water collected from a pond. The reviewer mentions that the pond has a lot of plants and small fish and amphibian egg sacs in it, which would suggest its not heavily contaminated by toxins but notes that it is always a good idea to treat water collected in the wild as if it is contaminated, as it is impossible to know what may be in it, even in pristine water, especially bacteria. The reviewer then goes on to explain how to use the GeoPress, which uses an activated charcoal filter and mechanical filtration to remove bacteria, protozoa, and other contaminants from the water. The reviewer also mentions that it is possible and recommendable to pre-filter the water by using a cotton bandana to remove larger debris, but in this instance, they choose not to do so. Finally, the reviewer tastes the water after filtering it and confirms that it is clean and safe to drink.
