Explain why reducing surface runoff is the most general way to reduce water pollution.?

Reducing surface runoff is crucial for minimizing water pollution because it directly decreases the amount of contaminants, such as fertilizers, pesticides, and sediments, that enter water bodies. By managing runoff through techniques like vegetation buffers, permeable surfaces, and proper land use practices, we can filter and absorb pollutants before they reach rivers, lakes, and oceans. Additionally, less runoff helps maintain the natural hydrology of ecosystems, promoting healthier water quality and biodiversity. Ultimately, controlling runoff serves as a proactive approach to protecting water resources from pollution.
