Soil Pollution

Today is World Soils Day, time to talk about soil pollution and wetlands! Soil pollution is often referred to as “invisible” because, although pollution can be detected through testing, it is much more difficult to see with the naked eye. Some of the biggest players in soil pollution today are improper waste management, agricultural runoff, and industrial processes. You may not think you are directly impacted by soil pollution, but you are.

Polluted soil in agricultural fields is arguably the most direct impact to humans because the pollutants are taken into the crop, whether it is a plant or animal, and make it into our food stream. [1] Pollutants in soils are also less hospitable to plant recruits, which is terrible news for coastal Louisiana. Our coastal wetlands provide us with many things that we rely on, and we cannot afford to lose our wetlands to preventable pollution. When soils do not incorporate healthy plant roots, they are much more susceptible to erosion. When moving sediments around, CWPPRA wants to make sure that plants can re-establish effectively, so they want healthy soils. [2]

Areas with unsustainable levels of pollution are spreading, and non-point source pollution, which includes road and agricultural runoff, is very hard to track and very hard to remedy. Pollutants are not easily scrubbed from soils on a mass scale and so they follow the flow of water. Runoff travels through watersheds just like clean water and makes its way into our coastal wetlands with damaging consequences. Coastal wetlands are resilient ecosystems, but they have limits. We cannot overburden them with harmful, carefree attitudes towards pollution. Our coast deserves to be protected. Our coast deserves to be respected.
