7.7.2.1 Source of Action City staff 7.7.2.2 Cooperators State and Anoka County agencies conducting geologic and hydrogeologic studies, well drilling companies, Wellhead Protection Consultant, and others. 7.7.2.3 Time Frame Ongoing beginning with approval of this WHPP. 7.7.2.4 Estimated Cost Approximately $1,000 to $1,500 for compiling data from other public sources. 7.7.2.5 Goals Achieved More accurate hydrogeologic data will be available for use in siting future wells and for future revisions of the delineated WHPAs and the DWSMAs for existing and proposed municipal wells. Updated and more accurate vulnerability assessments may be possible as a result of new information. Success criterion: Compilation of a geologic/hydrogeologic dataset that can be used in the future. 7.7.3 Updating of the Groundwater Model Used in the WHPA Delineations Any new local geologic and hydrogeologic data for the Ramsey area will be periodically reviewed to determine if the groundwater model used in the WHPA delineations will need to be updated. In addition, pumping from high capacity wells often changes over time. Changes in pumping from high capacity wells in or near the Ramsey DWSMAs could affect the DWSMA boundaries. Therefore, the City will work with the Wellhead Protection Consultant to review available information and determine if the groundwater flow model should be updated so that future WHPA/DWSMA delineations will be consistent with available information. 7.7.3.1 Source of Action City staff 7.7.3.2 Cooperators Wellhead Protection Consultant 7.7.3.3 Time Frame Five to seven years after approval of this Plan 7.7.3.4 Estimated Cost Approximately $1,000 to $5,000 depending upon the magnitude of the revisions needed to make the groundwater flow model consistent with the most current available information. 34
