According to the US. Environmental Protection Agency, stormwater runoff is the #1 source of surface water pollution.

The Mississippi River carries an estimated 1.5 million metric tons of nitrogen pollution into the Gulf of Mexico each year, creating a "dead zone" in the Gulf each summer about the size of New Jersey.

Each year 1.2 trillion gallons of untreated sewage, stormwater, and industrial waste are dumped into U.S. water.

Approximately 46% of the lakes in America are too polluted for fishing, aquatic life, or swimming.
