The Mississippi River is the most contaminated Fresh Water source in the United States. The HYDRO was taken to the Arch in Saint Louis and down to the bank of the Mississippi River. The HYDRO purified the river water, on camera–the footage is unedited and uncut! Unbelievable? In seconds we can filter out 99.99% of the contaminants in the good ol’ Mississip! Watch the video for the demonstration and lab test results of the BEFORE and AFTER! Believe it!
