A Public Water Supply Protection Overlay District is hereby created and divided into Zone A, Zone B and Zone C as follows.
(A) Zone A is identified as the primary source of water for the municipal well aquifer and as the area most likely to transmit ground water contaminants to the municipal wells. Zone A is more restrictive than Zone B. Zone A represents the area in which the time of travel of a contaminant to a well is one year or less.
(B) Zone B is identified as a secondary source of water for the municipal well aquifer and as an area where there is a lower probability of surface contaminants reaching the municipal well fields. Zone B is less restrictive than Zone A. Zone B represents an area in which the time of travel of a contaminant to a well is one year to five years.
(C) Zone C is identified as a tertiary source of water for the municipal well aquifer and as an area where there is an even lower probability of surface contaminants reaching municipal well fields. Zone C is less restrictive than Zone B. Zone C is an area in which the time of travel for a contaminant to a well is five years to ten years.
