Humber/Ontario Real Estate Course 3 Exam Practice

When buyer Colby decides to purchase a property with a well, what should they ensure to avoid water contamination?

1. Ensure the well cap is properly sealed as it prevents contamination.

2. Only sample water once every two years.

3. Make sure the well contractor prepares a record only if the well exceeds a 50-feet depth.

4. Sample water once after installation is sufficient.

5. The depth of the well is not related to contamination prevention.

The correct answer is: Ensure the well cap is properly sealed as it prevents contamination.

Ensuring that the well cap is properly sealed is crucial for preventing water contamination. A well cap acts as the first line of defense against surface contaminants such as bacteria, chemicals, and debris that can enter the well. When the cap is secure and sealed properly, it minimizes the risk of these pollutants seeping into the well water, thereby preserving the quality and safety of the water supply. Although other factors can contribute to water quality, such as regular testing of the water and the well’s depth, the immediate structural integrity of the well, represented by the condition of the well cap, plays a vital role in protection against contamination. Regular monitoring, sampling practices, and construction details are also important, but ensuring the well cap is sealed is a fundamental step in safeguarding the water source against potential contaminants from the surface.
