What impact can aging infrastructure have on water quality?

Aging infrastructure can significantly increase the risk of leaks and contamination in water systems. As pipes and other components of the water distribution system age, they may suffer from corrosion, structural failure, or cracks. These issues create vulnerabilities in the system, allowing contaminants from the surrounding environment, such as soil or wastewater, to enter the drinking water supply. Additionally, leaks can lead to water loss, reduced pressure in the pipes, and potential backflow issues where contaminated water can be drawn into the clean water supply.

In contrast, the other options do not accurately describe the impacts of aging infrastructure. Boosting water pressure, decreasing water demand, or improving the taste of water would not logically result from aging infrastructure. Instead, aging systems tend to compromise water quality due to physical deterioration and increased likelihood of contamination.
