Which of the following is a benefit of using green infrastructure for stormwater management?

• A. Increased runoff
• B. Improved water quality
• C. Higher construction costs
• D. Increased vulnerability to flooding

Answer: (B)

Using green infrastructure for stormwater management provides several benefits, one of which is improved water quality. This method incorporates natural processes and features, such as vegetation, soils, and natural hydrology, to manage stormwater. By allowing rainwater to infiltrate the ground and encouraging evapotranspiration, green infrastructure helps filter pollutants from the water before it reaches waterways. This approach can significantly reduce the quantity of pollutants, such as sediments, heavy metals, and nutrients, entering the stormwater system. For example, bioswales, rain gardens, and green roofs effectively remove contaminants and improve the overall health of local water bodies by mitigating water pollution. Hence, the emphasis on improving water quality stands out as a clear advantage of green infrastructure in managing stormwater effectively. Other options like increased runoff, higher construction costs, and increased vulnerability to flooding do not align with the primary advantages of green infrastructure, as these strategies primarily aim to enhance water management rather than exacerbate existing issues.
