What is the minimum separation distance between a water well and a school well?

• A. 100 feet
• B. 250 feet
• C. 150 feet
• D. 300 feet

Answer: (B)

Keeping wells far enough apart reduces the chance that contaminants or changes in groundwater flow around one well will affect the other, and it also minimizes interference between the wells’ draw zones. In Wisconsin practice, the minimum separation distance between a water well and a school well is 250 feet, which provides a buffer so surface or subsurface contamination sources near the school aren’t able to impact the other well, and so each well can reliably produce drinking water without shared contamination risks. If wells are closer, overlapping capture zones and faster potential transport paths increase the risk of cross-contamination and variability in water quality.
