In a grounding system, the recommended distance between the pipe and the anodes is critical for effective corrosion protection through cathodic protection systems. The correct understanding is related to maintaining an optimal relationship between the protective anodes and the structure being protected.

The concept of "within the area of influence" is essential in cathodic protection, where the anodes need to be positioned so that the protective current effectively reaches the entire area of the pipeline that requires protection. Keeping the anodes too far away can lead to inadequate protections, making option "within the area of influence" more favorable in practical applications.

When anodes are too close to the pipe, it can lead to localized areas of high current density, which might accelerate corrosion in those areas rather than prevent it, contradicting effective cathodic protection principles. Thus, having them "as close as possible" would not necessarily yield the best results, as it might cause unintended negative effects.

Setting up a distance "at least 5 feet apart" might not consider the specifics of the ground resistivity and the design parameters for the grounding system needed for effective electron flow and current distribution. Each grounding system is unique and may require specific distance settings based on those parameters.

Therefore, the focus is on achieving
