Which of the following is NOT allowed within 50 feet of a well?

The correct response indicates that all the provided options are activities that are not permitted within 50 feet of a well. This regulation is in place primarily to protect groundwater resources from potential contamination.

Septic tanks can introduce pathogens and other contaminants into the groundwater, making their proximity to water sources detrimental. Pumping stations can also pose risks due to the potential for fuel leaks or other hazardous materials that might enter the water supply. Cemeteries, while perhaps not an obvious threat, can lead to issues with leachate containing nutrients and pathogens from decomposing materials.

By prohibiting all these structures within 50 feet of a well, regulations ensure that the quality of the water drawn from wells remains safe for consumption and use, protecting public health and the environment.
