What is the isolation area distance for the land surrounding a well?

The isolation area distance for the land surrounding a well is established to protect the water source from contamination and to ensure safe drinking water. The correct answer reflects the widely accepted standard of a 200-foot isolation zone around a well. This distance is designed to provide a buffer that minimizes the risk of pollutants infiltrating the well through surface water or groundwater pathways.

Establishing this zone is a critical part of safeguarding public health and maintaining water quality, particularly in areas where potential contaminants might be present, such as agricultural land, septic systems, or industrial facilities. The 200-foot measurement is a balance between providing sufficient protection and being practical regarding land use, allowing for the responsible management of surrounding areas.
