Delineation of Ground Water Protection Zones Mobile App
Three zones are delineated around a well (see specific guidance for springs and horizontal wells), using the Calculated Fixed Radius method.
How does it work?
The default shape of these zones is circular and the radius of the zones is based on the Time of Travel (TOT) of water from a point in the aquifer to the well. There are more complicated methods for determining the size, shape and location of zones. Water systems interested in these methods should consult with a hydrogeologist or other knowledgeable professional. The Delineation of Ground Water Protection Zones mobile app has been developed to assist water systems and regulators in determining the procedures to use in delineating protection zones.
