What distance is required for wells and underground cisterns from drip irrigation systems?

The correct requirement for the minimum distance between wells and underground cisterns from drip irrigation systems is 100 feet. This regulation is in place primarily for health and safety reasons. Maintaining this distance helps to prevent potential contamination of groundwater sources. Drip irrigation systems often utilize fertilizers and other chemicals that, if improperly handled or disposed of, could seep into the ground and migrate towards a well or cistern. A buffer of 100 feet significantly reduces the risk of chemical leaching, ensuring that the integrity of the water supply remains uncompromised.

In contrast, shorter distances such as 10, 20, or 50 feet might not provide adequate protection against contamination, which is why they do not meet the required standards for safe separation between these systems. The importance of adhering to such guidelines is critical in preventing adverse health impacts associated with contaminated water supplies.
