Farms are a large nonpoint source because of the fertilizers and pesticides used. Unfortunately, runoff is becoming a major factor in water pollution. Sometimes after heavy rainfall, beaches have to be closed off due to runoff that includes sewage and other waste. Pollutants are becoming a tremendous problem and can destroy entire ecosystems. Biomagnification is organisms that are high on the food chain, which includes people, that are ingesting more pollutants since humans consume other foods that contain remnants of runoff. Runoff is also an economic downfall because many agribusinesses lose millions of dollars from runoff, which carries away the fertile layer of topsoil, a vital crop factor. Luckily, there are still actions that can be done to prevent runoff from becoming a bigger problem. One solution that everyone can do is for farmers to reduce the amount of fertilizers that are used, decrease the amount of materials that do not allow liquid to pass through, and communities can plant more native vegetation, which could prevent erosion and runoff from entering waterways. An engineering solution that can be invented is the Soil
