Humber/Ontario Real Estate Course 3 Exam Practice

Buyer Taylor interested in a property with a drilled well, should take which precautionary measure to ensure clean drinking water?

1. Ensure the well remains open for regular inspections.

2. Ensure the well casing is buried completely for protection.

3. Ensure the well seal and cap are secure against water entry.

4. Ensure adjacent ground elevation slopes towards the well.

5. Ensure the well location is in a low-lying area.

6. Use only plastic covers for the well opening.

The correct answer is: Ensure the well seal and cap are secure against water entry.

The correct choice emphasizes the importance of maintaining the integrity of the well's seal and cap. A secure well seal and cap are critical for preventing contaminants from entering the well water. Over time, factors such as weather, animal activity, and debris can put the water quality at risk if the sealing is compromised. A robust cap and seal help safeguard the water from surface contaminants and pathogens, which can pose serious health risks. In terms of the context of the other options, while regular inspections (the first option) are indeed vital for overall maintenance, they do not serve the same immediate protective function as a secure well seal and cap. The second choice regarding the casing suggests that burial is beneficial, but it does not address the direct impact of covering the water source itself. Ensuring proper drainage away from the well (the fourth option) is often good practice, but it does not prevent contamination at the entry points of the well. The fifth option, discussing low-lying areas, poses additional risks since water accumulation can increase flooding possibilities, thereby contaminating the well. Finally, using plastic covers (the last option) may not address the critical concern of secure sealing against contaminants, assuming that plastic material itself is inherently safe.
