For those serviced by a private well, what is the minimum lot size required?

The minimum lot size required for those serviced by a private well is typically established based on the need to ensure safe drinking water and to protect the water quality. In many jurisdictions, a one-acre lot is deemed sufficient to provide adequate space for a well, septic system, and any necessary setbacks to prevent contamination from surrounding activities.

The one-acre requirement is based on health standards that consider factors such as the distance from potential contamination sources, the capacity of the well to provide adequate water supply, and the ability of the land to assimilate wastewater without adversely affecting the groundwater. Larger lot sizes, such as two or three acres, while they may offer additional protection, are not universally necessary for all private wells, making one acre the minimum standard in many areas.

The other options imply larger lot sizes than what is typically mandated, which could lead to unnecessary restrictions in areas with adequate water resources and management practices in place.
