A wellhead protection plan must identify a strategy for evaluating the progress of the plan of action and the impact of a contaminant release on the aquifer supplying the public water supply well.
The evaluation strategy must:
be conducted throughout the drinking water supply management area;
be based on the health risk the specific potential contaminant source presents to the public water supply well; and
specify the evaluation approach used for specific potential contaminant sources.
Evaluation approaches are:
sampling the quality of the groundwater throughout the drinking water supply management area;
documenting inventory control of potential contaminants;
documenting the implementation of wellhead protection measures; and
using monitoring data already required by existing laws and rules in effect at the time of plan adoption.
An evaluation must be conducted:
every 2.5 years or less; and
An evaluation conducted in accordance with subpart 4, item B, must be submitted to the department at the first scoping meeting held to amend an existing plan.
