(r) “Wellhead Protection Zone 1 (WHPZ1)” means at a minimum, the area within the one year time-of-travel contour. The boundary can be changed to add areas outside the one year time-of-travel contour to ease its definition (i.e. use of street boundaries).
(s) “Wellhead Protection Zone 2 (WHPZ2)” means at a minimum, the area within or inside the five year time-of-travel contour, and outside the one year time-of- travel contour. The boundary can be changed to add area outside the five year time-of-travel contour to ease its definition (i.e. use of street boundaries).
