When it comes to preventing well water contamination, what is an important preventative measure?

1. The amount of well water depends solely on well depth

2. Ensure that the well cap is properly sealed

3. One water sample every three years is adequate

4. Well records are only prepared for wells over 100 feet in depth

The correct answer is: Ensure that the well cap is properly sealed

Ensuring that the well cap is properly sealed is an important preventative measure when it comes to preventing well water contamination. The well cap acts as a barrier, preventing surface substances such as bacteria, insects, or other contaminants from entering the well and affecting the water quality. A properly sealed well cap helps to maintain the integrity of the well system and safeguard the water supply. The other options are incorrect: A. The amount of well water does not solely depend on well depth; the well depth is just one factor that can affect the amount of water available in a well. C. Testing water samples more frequently than once every three years is typically recommended for ensuring water quality and identifying any contamination issues promptly. D. Well records should be prepared for all wells, regardless of their depth, to document important information about the well construction and history for future reference and maintenance purposes.
