Polluted Rivers, Streams and Lakes Unfit for Use
Covering about 70 percent of the earth, surface water is what fills our oceans, lakes, rivers, and all those other blue bits on the world map. Surface water from freshwater sources accounts for more than 60 percent of the water delivered to American homes. But a significant pool of that water is in peril. Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff. Municipal and industrial waste discharges contribute their fair share of toxins as well. There’s also the garbage and toxins that industry and individuals dump directly into waterways.
Farms, factories, municipalities, and individuals all contribute to this issue.
Surface water pollution greatly harms human health, and low-income communities are disproportionately at risk because their homes are often closest to the most polluting industries. Surface water pollution also has damaging effects on the environment, including the destruction of entire ecosystems.
