Water Pollution

In America 40% of rivers and 46% of the lakes are polluted and unsuitable for swimming, fishing or any other activity.

In 1975, the National Academy of Sciences estimated that ocean-based sources, such as cargo ships and cruise liners dumped 14 billion pounds of garbage into the ocean.

As per U.S. EPA estimates, every year in the U.S, 1.2 trillion gallons of sewage from household, industry, and restaurants is dumped into U.S. water annually.

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

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.

Approximately 40% of the lakes in America are too polluted for fishing, aquatic life, or swimming.

About 10% of America’s beaches fail to meet the federal benchmark for what constitutes safe swimming water.

Federal authorities estimate that the headwaters of 40 percent of Western rivers are tainted with toxic discharge from abandoned mines.

In the United States there are thought to be over 20,000 known abandoned and uncontrolled hazardous waste sites and these sites could contaminate the groundwater if there is a leak.

About 27 trillion gallons of groundwater are withdrawn for use in the U.S. each year.

Colorado Department of Natural Resources records show 450 abandoned mines are known to be leaking measurable toxins into watersheds. So far, 1,300 miles of streams have been impaired.

Colorado’s 7,300 abandoned mine sites contain about 17,000 point sources of pollution, such as open mine shafts and tunnels.

Point-of- use drinking water treatment through chlorine and safe storage of water could result in 122.2 million avoided DALYs (Disability Adjusted Life Years, a measure of morbidity), at a total cost of US 11.4 billion.

An estimated 500,000 abandoned mines in the U.S. will cost $20 billion in management and remediation of pollution; many of these sites will require management in perpetuity.
