San Antonio — Very Hard to Extremely Hard WaterRenowned for The Alamo and its beautiful River Walk, San Antonio also has a reputation for some of the hardest water in the country. San Antonio is also where Jason's Water Systems headquarters is located.
The Mississippi RiverThis once pristine waterway is perhaps the most polluted in the United States. Part of the problem stems from agriculture. The Mississippi River traverses much of America's heartland, drawing no end of runoff from factory farms. Animal waste isn't the only problem.
While there are a few places that boast extremely clean water, such as Canada, Iceland, Antarctica, or even Upstate New York, the team of scientists determined that the cleanest water in the world was in the Patagonia region of Chile, Puerto Williams.
