What preventative measure relates to well water contamination?

1. A sound preventative measure relating to well water contamination is to ensure that the well cap is properly sealed.

2. One water sample every three years is adequate for most recreational property wells.

3. Well contractors only prepare well records for wells that exceed 100 feet in depth.

4. The amount of well water available for use in a well system is solely related to the depth of the well.

The correct answer is: One water sample every three years is adequate for most recreational property wells.

The most effective preventative measure concerning well water contamination is ensuring that the well cap is properly sealed. A well cap acts as a barrier protecting the water supply from contaminants, such as bacteria, chemicals, and debris. If the well cap is not sealed correctly, it can allow surface water or foreign objects to enter the well, which poses a significant risk to water quality. While testing well water periodically is important for detecting contamination, relying on one water sample every three years may not provide a complete picture of the water's safety, especially for recreational properties that might experience varying levels of contamination due to factors like seasonal use or nearby pollution sources. The idea that well contractors only prepare records for wells deeper than 100 feet does not encompass the need for proper documentation of all wells, regardless of depth, especially since both shallow and deep wells can be susceptible to contamination. Finally, the accessible amount of well water is influenced by various factors like geological conditions, aquifer characteristics, and well design, not solely by the well's depth. A comprehensive approach to well management and maintenance is essential for ensuring water safety.
