Which two water sources share the same minimum distance of 100 feet?

The main idea is that certain surface water features used for drinking water protection require the same setback distance from a septic system. Class I reservoirs and permanent stormwater retention ponds are both surface water sources with a high potential to affect water quality, so the rule assigns them a 100-foot minimum distance. That shared distance helps reduce the chance that effluent could contaminate drinking water or degrade surface water quality. Other water sources listed have different regulatory distances due to their classification or use, and nitrification fields or repair areas are parts of the septic system, not separate water sources, so the same 100-foot rule doesn’t apply to them in the same way.
