The purpose of the Wellhead Protection District
3 is to protect the zone of contribution to the aquifer that recharges
the Alfred Water District wells from land uses which pose a threat
to the quality and/or quantity of the groundwater extracted for public
use.
The boundary of the Wellhead Protection District
3 corresponds to the area defined as "Approximate Zone of Contribution
for PW-1; " established by geologic study and numeric modeling, performed
by Emery & Garrett Groundwater, Inc., in February 2004 (Job Number:
ME 0366) and approved by the Maine Department of Health and Human
Services Drinking Water Program on February 20, 2004. The location
and boundaries of the Wellhead Protection District 3 are established
as shown on the Official Zoning Map and are hereby made a part of
this chapter.
