In the holding tank example, which distance is cited as being too close to the uncased water supply well?

• A. 10 meters
• B. 7 meters
• C. 5 meters
• D. 35 meters

Answer: (A)

The key idea is protecting drinking water by keeping wastewater sources at a safe distance from water wells. An uncased water supply well has exposed soil around it, so contaminants can move more easily from nearby sources into the well through groundwater or surface pathways. In this holding tank example, the distance identified as being too close is the smallest measurement listed. When a source like a holding tank sits near a well, that close proximity increases the chance that wastewater could reach the well, especially during spills or groundwater movement. Distances that are farther away provide more separation and typically meet regulatory setback requirements, making them not considered too close. Always follow local codes for the exact minimum distance, but the principle remains: the closer the holding tank is to the uncased well, the higher the contamination risk, so the smallest distance in the given options is the one flagged as too close.
