The Mississippi River is the fourth longest and tenth largest river system in the world; it runs through many United States cities including Minneapolis and New Orleans. In the 19th century, it became a lifeline and a major economic hub along its 2,320 miles of waterway. Unfortunately, the Mississippi River has become so polluted that it has earned the title of the most polluted river in America.<\/p>\n

Long before development and population growth spread along the Mississippi, the waterway was one of the most pristine and beautiful in the United States. As the population began to grow, the development along the banks led to increases in industrial runoff, sewage, oil and other pollutants entering the river. This, combined with the effects of oil spills, caused bacteria levels to skyrocket, resulting in many areas of the river becoming devoid of water life.<\/p>\n

The most significant cause of the Mississippi River’s pollution is the increased agricultural runoff from rural areas of the states along the river. This runoff carries with it high levels of nutrients such as nitrates and phosphates which can cause algal blooms – resulting in oxygen depletion and death of fish. Additionally, this nutrient runoff is often contaminated with various chemicals, herbicides and pesticides, further damaging the quality of the riverwater.<\/p>\n

The next major cause of the Mississippi’s pollution is the excessive amounts of industrial wastewater that are discharged directly into the river. These wastewater releases often contain high concentrations of heavy metals, chemical additives and industrial compounds that have contributed to the death of fish and other wildlife, as well as hazardous health dangers to humans. In addition to this, these contaminated wastewaters create an oxygen-depleted environment in the river, inhibiting the growth of fish and other species.<\/p>\n
