As communities across America struggle to come to terms with pollution, it becomes increasingly crucial to understand which rivers are the most polluted and why. The Mississippi is often seen as the most polluted river in America, however, the St. Croix river is also home to significant pollution. Both rivers suffer from industrial and agricultural pollution, with long-term effects on the environment, local populations, and the wildlife that calls each body of water home. The question then remains, is the Mississippi more polluted than the St. Croix?<\/p>\n

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

In terms of volume and scale, there is no denying that the Mississippi has some of the worst water pollution in the United States. This is in part due to its vast size, however, its geographic location also contributes to its contamination. Multiple states and cities use the Mississippi River as a wastewater dumping ground, with many of the bigger cities located within its watershed. Combined, they discharge millions of tons of industrial waste and agricultural runoff into the river. Additionally, pharmaceuticals, nutrients and hazardous materials such as heavy metals and chemicals are found in the river, creating contaminated hotspots along its banks.<\/p>\n

The consequences of this have been severe, with a drastic decline in water quality since the 1960s. Several species of fish have become endangered, including the American eel, the pallid sturgeon, and the shortnose sturgeon. The bottom-dwelling organisms in the river have also suffered as a result of erosion and sedimentation. Furthermore, this water contamination poses a threat to the health of local communities, and the river has become increasingly inhospitable to various species of birds, mammals, and aquatic life. <\/p>\n

Pollution in the St. Croix River<\/h2>\n

The St. Croix River is significantly smaller than the Mississippi and is located in Minnesota and Wisconsin. Similarly, the St. Croix is subject to agricultural and industrial pollution, with toxic runoff from animal agriculture and wastewater being a major concern. The effects are far-reaching, and some species in the St. Croix have been contaminated with heavy metals and PCBs. Additionally, extreme acid mine drainage in nearby waterways taints the water, and the nearby Lake St. Croix has registered phosphate levels around nine times higher than the maximum recommended levels.<\/p>\n
