Under Virginia environmental regulations, what is the minimum distance a septic system drain field must be from a private well?
Correct Answer
C) 100 feet
Virginia environmental regulations require septic system drain fields to be located at least 100 feet from private wells to prevent groundwater contamination.
Why This Is the Correct Answer
Virginia environmental regulations require septic system drain fields to be located at least 100 feet from private wells to prevent groundwater contamination.
Why the Other Options Are Wrong
Option A: 75 feet
75 feet is insufficient under Virginia regulations. While some jurisdictions use this distance, Virginia's groundwater protection standards require a greater separation to prevent bacterial and pathogen contamination.
Option B: 150 feet
150 feet is more than required and may be confused with setbacks from public water supplies or streams. Virginia's minimum for private wells is 100 feet.
Option D: 50 feet
50 feet is dangerously close and well below Virginia's minimum. Such a short distance could allow effluent to migrate through soil and contaminate the well before adequate filtration occurs.
Memory Technique
100 feet = 1 football field end zone to end zone is 100 yards, but think of 100 feet as your 'private well protection zone.' If the drain field is within one basketball court length (roughly 94 feet), it's too close — round up to 100 feet to be safe and code-compliant.
