Toxicity in the Mississippi River<\/h2>\n

Among the sources of water pollution in the United States, the Mississippi River stands out as a prime example of environmental harm caused by human activity. Its waters are contaminated with toxic chemicals, sewage, agricultural runoff and other pollutants that have built up since the industrialization of the Mississippi basin. While the river provides important ecosystem services and supports human life, its poor quality is a serious threat to public health, fish and wildlife, and other life forms. <\/p>\n

The Mississippi River is the fourth-longest river in the world, with a total length of 2,320 miles and covering 41 percent of the continental United States. Beginning in Minnesota and ending in the Gulf of Mexico, the Mississippi flows through 10 states and 45 different cities. It is a vital source of water for agricultural, recreational, and domestic purposes. It also provides refuge for countless birds, fish, and other wildlife. As the major outlet for the majority of the waters flowing into the Gulf of Mexico, the Mississippi has been significantly affected by human activities.<\/p>\n

Toxic chemicals like PCBs, petroleum, and pesticides are some of the main pollutants responsible for making the Mississippi River unsafe. The pollutants enter the river in various ways. For example, runoff from agricultural land, forestry, urban runoff and industrial discharge all contribute to the toxic mix. In addition, the untreated sewage that flows into the river contains dangerous bacteria and other pathogens, which can cause diseases in both humans and natural species. The discharge of wastewater from industries, such as paper mills, also adds to the amount of toxins pressed into the Mississippi’s waters. <\/p>\n

The danger posed by these pollutants varies greatly depending on their concentration in the river. The U.S. Environmental Protection Agency (EPA) has set limits for certain chemicals, yet due to the large amounts of pollutants entering the river, some concentrations still exceed EPA standards. For instance, phosphorus, one of the major sources of water pollution due to agricultural runoff, can have adverse effects on aquatic life. The EPA has set the threshold for phosphorus concentrations to 0.10 parts per million, yet in some parts of the Mississippi River, it is found at levels as high as 0.35 parts per million. <\/p>\n
