Which of the following is a consequence of well casings not being properly sealed?

• A. Groundwater contamination
• B. Increased water pressure
• C. Better water taste
• D. Decreased risk of contamination

Answer: (A)

Groundwater contamination is a significant consequence of well casings not being properly sealed. Well casings are intended to protect the groundwater source from surface contaminants and to prevent the migration of unfiltered water from the surrounding environment into the water supply. When the casing is improperly sealed, it creates a pathway for contaminants, such as bacteria, chemicals, or sediments, to enter the aquifer. This can lead to potential health risks for individuals consuming the water, as well as adverse environmental impacts. In contrast, the other options do not accurately reflect the consequences of improper sealing of well casings. Increased water pressure, better water taste, and decreased risk of contamination are not outcomes associated with defective sealing. Rather, they imply scenarios that could lead to either water quality improvements or reduced risks, which are not feasible in situations where the integrity of the well casing is compromised.
