Humber/Ontario Real Estate Course 2 Exam Practice

What is the best course of action if contamination is found in a water well on a property?

1. Investigate surface water drainage issues.

2. Seal off the well from outside sources.

3. Redrill the well with larger diameter piping.

4. Check for natural underground contamination.

5. Verify structural integrity of the well casing.

6. Test for shallow water penetration.

The correct answer is: Redrill the well with larger diameter piping.

When contamination is found in a water well on a property, the best course of action is to redrill the well with larger diameter piping. This is because larger diameter piping can help in ensuring that the water supply is not affected by the contamination present in the previous well. By drilling a new well with larger piping, the property can avoid the risk of continuing contamination and provide a safer water source for the inhabitants. The other options are not the best course of action in this scenario: - Investigating surface water drainage issues (Option A) may be necessary to prevent future pollution, but it does not address the current contamination in the water well. - Sealing off the well from outside sources (Option B) might not completely solve the contamination issue if the source of contamination is already within the well. - Checking for natural underground contamination (Option D) is a general step that should be taken, but it does not directly resolve the contamination in the water well. - Verifying the structural integrity of the well casing (Option E) is important for ongoing maintenance but will not eliminate the current contamination. - Testing for shallow water penetration (Option F) is important for understanding potential sources of contamination but does not directly address the issue at hand.
