Agricultural Runoff: Pesticides and fertilizers from farms run off into nearby water bodies, affecting water quality

Agricultural runoff is a significant contributor to water pollution in Mexico City, and it poses a critical environmental challenge. When it rains, pesticides, fertilizers, and other chemicals used in farming practices are carried by rainwater from fields into nearby rivers, streams, and eventually, the city's water sources. This process has detrimental effects on water quality and the overall health of aquatic ecosystems.

Farms often use pesticides to protect crops from insects and diseases, and while these chemicals can be effective, they are not without consequences. When it rains, the pesticides wash off the fields and enter the water bodies, leading to a process known as pesticide contamination. This contamination can result in the accumulation of toxic substances in the water, making it unsafe for human consumption and harmful to aquatic life. The impact is particularly severe in urban areas where agricultural activities might be less regulated.

Fertilizers, another common agricultural chemical, play a role in this pollution as well. Farmers use fertilizers to enhance crop growth, but excess nutrients, such as nitrogen and phosphorus, can be washed off the fields during heavy rainfall. These nutrients act as pollutants when they enter water sources, causing a phenomenon known as eutrophication. This process promotes excessive growth of algae and aquatic plants, depleting the water of oxygen and creating dead zones where fish and other organisms cannot survive.

The consequences of agricultural runoff are far-reaching. As polluted water flows into the city's water bodies, it can contaminate drinking water sources, posing risks to human health. Additionally, the pollution affects the city's aquatic biodiversity, disrupting the delicate balance of ecosystems. To address this issue, sustainable farming practices should be adopted, including precision agriculture techniques, to minimize the use of chemicals and reduce the impact on water quality.
