Okavango Challenge

I’m doing a project about water pollution. I need the total percentage that Earth’s water pollution has increased, if it has, or decreased, which I doubt. I mainly need it for the United States, but overall is fine.
I’m doing a project about water pollution. I need the total percentage that Earth’s water pollution has increased, if it has, or decreased, which I doubt. I mainly need it for the United States, but overall is fine. I need to know impurities in bottled water, tap, drinking, rivers, oceans, etc. All types of water.

For many years the U.S. was making great headway in cleaning rivers, but the Bush administration placed pro-business people in charge of the E.P.A. and other federal agencies charged with guarding water quality. These appointees undercut monitoring of water quality. They ignored issues like power plant emissions that cause mercury pollution of waterways. Their intent is to lower costs for businesses.

Below are some links. However, it is difficult to find an easy-to-read chart with the info you ask for.
