What is the main purpose for developing monitoring wells?

• A. To obtain representative water samples
• B. To increase groundwater levels
• C. To reduce pumpage
• D. To prevent contamination

Answer: (A)

Monitoring wells are installed to access groundwater from a specific part of the aquifer and to collect samples that truly represent the conditions there. The main purpose is to obtain representative water samples so you can measure the concentration of constituents, track changes over time, and detect or monitor contamination and plume movement or remediation effectiveness. Achieving representativeness relies on proper well design, including the screen interval and placement, and on sampling practices such as purging before collection to avoid biased results from stagnant water or mixing with other layers. This sampling-focused role is what makes monitoring wells essential. The other options describe actions that involve management or protection measures rather than the core function of the well itself.
