A suite of geophysical logs were run in both wells under non-pumping conditions to identify the major aquifers and confining units and estimate the flow between aquifers under static conditions.  A second suite of logs was run in each well while pumping.  The wells were pumped at a rate of 430 to 550 gpm to purge the individual producing zones.  Flow meter logs were run while pumping to determine the relative production of each producing zone.  The results of the dynamic logs were used to select water sampling depths using a down hole discrete sampler.  The water samples were analyzed for major ions, radium and gross alpha.
In Well 2, we sealed a high radium interval in the upper part of the borehole by hanging a packer on the pump column at 870 feet and pumping from below the packer.  In Well 3 we sealed a high radium zone in the lower portion of the borehole by backfilling to 1,130 feet with grout.  Several low radium zones were selectively stimulated in both wells using the Airburst^TM method.  Radium levels in Well 2 were reduced from 5.7 pCi/l to 3.2 pCi/l with a reduction in specific capacity of about 30%.  Radium levels in Well 3 were reduced from 5.3 to 3.5 pCi/l, with a reduction in specific capacity of about 25% to 35%.
