Introduction


Purpose of this Document
The purpose of this document is to provide recommendations to the State of Minnesota for public
drinking water suppliers relying on surface waters regarding the:
Identification of the meaning of protection.
Identification of the lead state agency for coordinating the development of protection.
Identification of the content of a source water protection plan.
Identification of the method(s) and criteria for the delineation of source water protection areas.
Identification of a method of potential contaminant source inventory that is practical.
Identification of a consistent statewide procedure for the development and implementation of the
source water protection plans.
Identification of a review and endorsement/approval process.
Exploration of the establishment of an oversight entity to guide the development and
implementation of source water plans within a watershed or throughout a river basin.
Identification of funding sources for the development and implementation of source water
protection plans; and
Relationship of source water protection plans with other plans, such as local water plans, watershed
plans, basin plans, and other local land-use plans.

It is recognized that the development of source water protection plans is voluntary. However, if a plan
is to be endorsed/approved by the state and local units of government, there are certain minimum
