Select the best answer for the question. Which process causes wells on land to become saline, making them unusable for drinking water?
A. Echo sounding
B. Eutrophication
C. Groundwater infiltration
D. Erosion
Answer (2)
Wells become saline due to groundwater infiltration, which allows seawater to intrude into freshwater aquifers, particularly in coastal areas. This intrusion can result from over-extraction of groundwater and reduced aquifer pressure. Recognizing this process helps highlight environmental management practices to maintain water quality. ;
The best answer to the question about wells becoming saline is Groundwater infiltration , which occurs when saltwater intrudes into freshwater aquifers due to over-extraction and reduced pressure. This is particularly problematic in coastal regions where sea levels rise. Understanding this process is crucial for managing water quality effectively.
