10 'dying' rivers of America (Part 1)

Do you know more than 250,000 large and small rivers exist in the Americas? It is a very large number and it is inevitable that one of those rivers is polluted. For many different reasons, but most of the people living near the river basin or improper mining can push large rivers, supplying water to millions of people and being threatened. threatening, causing bad influence.

Here are the names of the rivers that are being alarmed on the list of " Rivers in America in danger" .

1. Susquehanna River

Susquehanna River

With a total area of ​​71,000 square kilometers, the Susquehanna River consists of two-thirds of Pennsylvania, part of New York and part of Maryland. This flow also passes through the Marcellus Shale area (where people use gas) before pouring into Chesapeake Bay.

Although environmental researchers have referred to the Susquehanna River as "the most threatening US river in 2005", it is a source of water for more than six million people.

After 26 years, the list of "dangerous rivers in the United States" not only refers to the most polluted river, but a warning to the river that will "rise to the throne" next year. And Susquehanna led the list this year, because it flows through the region as the nation's goal of storing natural gas Marcellus Shale.

Marcellus Shale natural gas storage area

The process used a large amount of water to extract gas. They mixed water with sand, other chemicals and pumped them into the ground to create great pressures. It will cause cracks in the rocks and allow natural gas or oil to be kept on the ground.

Scientists are worried because most water treatment facilities cannot afford to handle hazardous substances and cause cancer by waste water.

They also fear that the current regulations cannot prevent the contamination of groundwater and people's drinking water. The oil spills threatened the Susquehanna River and its tributaries.

After becoming the most threatened river in the United States last year, due to gas leaks, Upper Delaware River Basin managers increased strict regulations to limit that.

Certainly, the Susquehanna River basin managers will also offer appropriate solutions to reduce and prevent current pollution here.

2. Bristol Bay

The stream near Pebble mine

Bristol Bay in Alaska is home to a wide range of rivers, including Nushagak and Kvichak, so it has become a "home" of the world's wildest trout. For more than 10,000 years, indigenous people have harvested a lot of salmon because they still come back here after the migration season.

But there was a proposal to build a good mine in the Nushagak and Kvichak watersheds. There are many people who oppose the Pebble mines producing this copper and gold, because they calculate that it will consume 35 billion gallons (140 billion liters) of water of the nearby stream every year.

At the same time it produces 10 billion tons of waste including antimony, arsenic, copper, manganese, molybdenum, zinc, selenium , and sulfate.

3. Roanoke River

The Roanoke River flows from the Blue Rigde Mountains in Virginia to northern California. Its flows provide drinking water to more than one million people on Virginia, Norfolk, and other communities.

The Commonwealth of Virginia's state legislature is considering lifting the ban on uranium mining in 1982, which will provide an opportunity for the company to exploit.

Other environmentalists say that if green light is exposed to uranium, it could threaten Roanoke's ecosystem as well as the supply of drinking water in areas with radioactive contamination and toxic chemicals. . In Virginia often has heavy rains, it will be difficult to protect waste containing radioactive substances. Uranium mining at other locations, including the Southwestern United States, will have health impacts in nearby communities: both cancer, birth defects, hormonal disorders, and photo-inducing Enjoy important organs.
