Which of the following is a consequence of increased runoff in urban areas?

• A. Improved water quality
• B. Reduction in local flooding
• C. Increased pollution in nearby waterways
• D. Enhanced soil fertility

Answer: (C)

Increased runoff in urban areas often leads to greater volumes of water flowing into nearby waterways during rain events. This runoff typically picks up various pollutants, including heavy metals, oil, chemicals, and sediments from impervious surfaces such as roads, rooftops, and parking lots. Consequently, the water that is discharged into rivers, lakes, or oceans becomes contaminated, leading to increased pollution levels in these aquatic systems. This pollution can harm aquatic life, disrupt ecosystems, and degrade water quality, highlighting the negative environmental impact of urban runoff. The other options do not accurately reflect the typical outcomes of increased runoff; instead, they present scenarios that are contrary to what generally occurs in urban runoff situations.
