What issue arises from special water users like golf courses in Arizona?

The issue that arises from special water users, such as golf courses in Arizona, primarily concerns the degradation of water quality. Golf courses often require large amounts of water, which can lead to the over-extraction of local water resources. This over-extraction can result in changes to the hydrological balance in the area, potentially leading to lower water tables and reduced availability of clean water.

Furthermore, the use of fertilizers and pesticides on golf courses can contaminate water sources and contribute to pollution. When runoff occurs, these chemicals can make their way into nearby waterways, negatively impacting water quality for both local ecosystems and human consumption. This situation underscores the tension between the recreational and commercial benefits provided by such water users and the need to protect the overall quality of water in the region.

In contrast to the other options, economic output and groundwater recharge would not directly address the concerns raised by water consumption practices, while increased water conservation, while beneficial, does not specifically relate to the unique challenges posed by special water users like golf courses in the context of degraded water quality.
