Was the Mississippi River ever clean?
Bacteria, lead, toxic chemicals have plummeted since 1972 The Mississippi River doesn’t have the cleanest reputation. Long treated as a drain for Midwest farms, factories and cities, the river has coursed with a nasty mix of bacteria, lead and toxic chemicals.
Does the Mississippi River have a history of pollution?
At least 144 million gallons of sewage and garbage were being tossed into the river every single day by the 1930’s. The pollution in the river caused disease outbreaks such as the typhoid outbreak in the late 1800’s to the early 1900’s.
Why does the Mississippi River look so muddy?
As the Mississippi River snakes past St. Cloud and the Twin Cities and eventually flows south into the Gulf of Mexico, it often appears brown or yellowish and is sometimes referred to as the Muddy Mississippi. The sediment runs off from farm fields and or washes into the river from eroding stream banks.
How has the Mississippi River been polluted?
Pollutants from booming farms combined with record wet weather are contaminating the nation’s mightiest waterway. Fertilizer and manure used on farms contain nitrogen and phosphorus. Flushed into waterways, they can taint drinking water and foster algae that chokes out marine life.
Is the Mississippi river the most polluted?
More than 12.7 million pounds of toxic chemicals such as nitrates, arsenic, benzene and mercury were dumped into the Mississippi River in 2010, according to a report released today by the advocacy group Environment Missouri.
What’s wrong with the Mississippi river?
The Mississippi River and its tributaries have been plagued by nutrient runoff, specifically excess nitrogen and phosphorous. All of that nitrogen and phosphorous runoff ultimately ends up in the Gulf of Mexico, triggering rapid overgrowth of algae.
What makes the Mississippi River toxic?
Agricultural Runoff is one of the leading causes of water pollution in the United States. Current agricultural practices lead to nutrient loading and in turn to eutrophication. One of the main problems in attempts to regulate this type of pollution is that it is non-point source.
Does the Mississippi River stink?
Another smell not all towns have is the smell of the mighty Mississippi. The tangy, often faint smell wafts over Vidalia and Natchez if the wind is just right.

Why is the river water brown?
The most common cause for water to change color is minerals. Erosion from river banks brings soil into the river, changing the color. After heavy storms, many rivers run brown from all the runoff flowing into the river. Clay can cause rivers to be murky whiteuddy brown, or yellow.
Where is the Mississippi River Clear?
From its headwaters at Lake Itasca and down through northern and central Minnesota, the Mississippi River is relatively clean and clear. But the river’s color — and water quality — changes rather dramatically as it flows south through farmland and urban areas.
Is the Mississippi River losing water?
The Mississippi River Delta and coastal Louisiana are disappearing at an astonishing rate: a football field of wetlands vanishes into open water every 100 minutes. Since the 1930s, Louisiana has lost over 2,000 square miles of land, an area roughly the size of Delaware.
What’s wrong with the Mississippi River?
The Upper Mississippi River is known for its pristine water quality near its headwaters in north-central Minnesota. But just downstream, too much sediment — small particles of sand, silt and clay — is a problem for the iconic river.
Why is there a sediment problem in the upper Mississippi?
In addition, soil particles absorb warmth from the sun, increasing the water temperature in streams and rivers. The draft report is a follow-up to a 2017 MPCA study, which identified excess sediment as a problem in this stretch of the Upper Mississippi.
What was one of the pollutants of the Mississippi River in the 1800s?
This was one of the pollutants of the Mississippi River in the 1800’s. Other pollutants such as garbage waste and chemicals were being dumped into the river. At least 144 million gallons of sewage and garbage were being tossed into the river every single day by the 1930’s.
What is the drainage basin of the Mississippi River?
The Mississippi River has the world’s fourth-largest drainage basin (“watershed” or “catchment”). The basin covers more than 1,245,000 square miles (3,220,000 km 2), including all or parts of 32 U.S. states and two Canadian provinces. The drainage basin empties into the Gulf of Mexico, part of the Atlantic Ocean.
