Thanks. I’ve looked at some, but I guess I’ve been suspicious that they will actually make, say, suburban creek water potable.
Well. I was suspicious of the claims as well. So I sent off a filtered water sample to a testing company. It was rather expensive. The test results said that the filtered water from our catch basin was potable. So if you want peace of mind ya have to test the filtered water. I had no confidence in the cheaper test kits I found on Amazon.
