There are hereby established use districts to be known as Zones One, Two, Three, and Four of the drinking water source protection area, identified and described as follows.
(A) Zone One is the area within a 100-foot radius from the wellhead or margin of the spring collection area.
(B) Zone Two is the area within a 250-day groundwater time of travel to the wellhead or margin of the spring collection area, the boundary of the aquifer(s) which supplies water to the groundwater source, or the groundwater divide, whichever is closer. If the available data indicate a zone of increased groundwater velocity within the producing aquifer(s), time-of-travel calculations shall be based on this data.
(C) Zone Three is the area within a three-year groundwater time of travel to the wellhead or margin of the spring collection area, the boundary of the aquifer(s) which supplies water to the groundwater source, or the groundwater divide, whichever is closer. If the available data indicate a zone of increased groundwater velocity within the producing aquifer(s), time-of-travel calculations shall be based on this data.
(D) Zone Four is the area within a 15-year ground water time of travel to the wellhead or margin of the spring collection area, the boundary of the aquifer(s) which supplies water to the groundwater source, or the groundwater divide, whichever is closer. If the available data indicate a zone of increased groundwater velocity within the producing aquifer(s), time-of-travel calculations shall be based on this data.
