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