Determine whether existing pumping information for community wells offsets the need to conduct pumping tests to satisfy the wellhead protection rule requirements. - 1. Cities will compile the test pumping information for each well in their system that was collected when the well was constructed or after it has been serviced or repaired. Pumping tests should consist of at least 24 hours of pumping or recovery data for wells completed in a confined aquifer or at least 72 hours for wells completed in unconfined aquifers. Target date for completion - April 1, 1997. 2. Review pumping test data to determine whether additional pumping tests will be needed to characterize transmissivity for the aquifers used by the communities in the Anoka joint powers boar group. Target date - May 1, 1997. Lead agency - MDH. 3. If needed, identify locations where additional pumping tests should be conducted to characterize aquifer transmissivity. Target date - June 1, 1997. Lead agency - MDH 4. Conduct needed pumping tests. Target date for completion of tests and data analysis - October 1, 1997. Lead agency - MDH with participation by the city in which a pumping test is conducted. Characterize groundwater withdrawal by community wells. - 1. Collect the annual amount of groundwater pumped by each well in a community water system for the previous five years (1991 - 1996). Also, estimate the amount to be pumped annually for the next five years. Target date for completion - May 1, 1997. Lead agency - Each community will collect its own data. MDH will compile it into a county-wide table by November 1, 1997. 3
