7.7.3.5 Goals Achieved <br />The groundwater flow model used in the WHPA delineations will be consistent with available information. <br />Since the groundwater flow model used to delineate the WHPAs will be consistent with current <br />information updating of the WHPAs in the future can be done more efficiently. <br />Success criterion: An updated groundwater flow model that can be used for future updates to Part 1 of <br />the City's WHPP. <br />7.7.4 Potential Contaminant Source Database <br />The City will periodically update the information on potential contaminant sources within the DWSMAs <br />collected during the development of this WHPP, with the assistance of the Wellhead Protection <br />consultant, if needed. The City will add information to the potential contaminant source database as <br />additional potential contaminant source sites are identified or as sites are closed through working with <br />the MPCA, the MDH, the MDNR, the U.S. EPA, and Anoka County. New information for the PCSI database <br />will be obtained by contacting appropriate MPCA, MDH, MDNR, U.S. EPA, and County programs between <br />years four and six of Plan implementation. <br />7.7.4.1 Source of Action <br />City staff. <br />7.7.4.2 Cooperators <br />MPCA, MDH, MDNR, U.S. EPA, Anoka County staff, and the Wellhead Protection Consultant, if needed. <br />7.7.4.3 Time Frame <br />Between years four and six after approval of this Plan. <br />7.7.4.4 Estimated Cost <br />Approximately $500-$2,500 that includes City staff time and, if needed, Wellhead Protection Consultant <br />costs. Actual costs will depend upon the amount of new potential contaminant source location <br />information that must be added to the potential contaminant source database (including location <br />verification) and in any year could be higher than the estimated range shown. <br />7.7.4.5 Goals Achieved <br />This database will be a useful tool to track, catalog, and document the status of potential contami nant <br />sources within the DWSMAs. <br />Success criterion: Maintaining an up to date potential contaminant source database. <br />7.7.5 Potential Contaminant Source Verification <br />Potential contaminant sources were identified within the DWSMAs during the PCSI. As part of the <br />development of this WHPP, all locations of identified potential contaminant sources were verified by the <br />Wellhead Protection Consultant to the extent possible based on the available data.
