Humber/Ontario Real Estate Course 3 Exam Practice

If a water test for a rural home shows fecal coliform, what does it indicate?

1. It's not a concern as a minor amount is typical.

2. Disinfecting the well with chlorine is a permanent solution.

3. There has been recent sewage contamination.

4. The water is safe for drinking but should be monitored.

5. The issue can be ignored if the home is not used frequently.

6. No other action is required if the property is not sold.

The correct answer is: There has been recent sewage contamination.

The correct answer indicates that the presence of fecal coliform in a water test is a clear sign of recent contamination, likely from sewage or animal waste. This suggests that harmful pathogens may be present in the water supply, which can pose serious health risks. Fecal coliform bacteria are often used as an indicator of potential contamination and the safety of drinking water. Therefore, identifying this type of contamination necessitates prompt action to address the underlying issue, such as investigating the source of the contamination and implementing measures to purify the water. It’s important for homeowners, especially in rural areas where wells are common, to understand the implications of such test results, as they can lead to serious health concerns if not treated properly.
