PUBLIC HEARING MINUTES FOR LAKE JANE JULY 24, 1985 PAGE 2 <br />The following are the <br />alternatives <br />that were suggested: <br />ALTERNATIVE <br />COST <br />COMMENTS <br />1. <br />Pump to Shafer Pit <br />$14,500 <br />tight underlying soils <br />2. <br />Excavate Shafer Pit <br />$35,000+ <br />questionable feasibility <br />3. <br />Excavate Shoreline <br />--- <br />questionable feasibility <br />4. <br />Irrigate Cropland <br />--- <br />not feasbile, pump limitations <br />5. Pump to alternate $16,000- appears most feasible <br />location 20,000 46 acre feet initial <br />3 acre feet/day <br />a. underlying soils <br />b. owner's concerns <br />c. counties' concerns <br />An area immediately south of the landfill was looked into and the <br />property is owned by Mervin Nippoldt. The City Engineer had not <br />been successful in reaching him. The Washington County Soil <br />Survey indicates that this depression which is about eight acres <br />in size should be able to percolate the amount of water necessary <br />to be removed. <br />There are about ninety days left in September, October and <br />November that effective pumping can be done. This should come <br />close to the 300 acre-feet of water that needs to be disposed of. <br />Because this proposal is new and there was limited time for <br />investigation, there are three unanswered questions. <br />a. Underlying soils - Not much is known about the soils. Don't <br />think there is a limiting layer under here like in the Shafer Pit, <br />but need more investigation. <br />b. Owner's concerns - have not been able to find out the owner's <br />concerns. Do know that the land is rented out for agricultural <br />purposes. There is small grain planted on there now and due to be <br />harvested in about three weeks, so the land may be available at a <br />crop standpoint. <br />C. Counties' Concerns - there are two concerns. There may be <br />some areas of trash in the old landfill that are below the present <br />water table. Therefore a greater volume of water in the water <br />table percolating may produce more leachate which will take a <br />longer time to clean up. When you deposit a large amount of water <br />in one.location, that creates a new slope on the ground water <br />table and it may interfere with the operation of their system. <br />They might have to operate that system longer to remove the same <br />amount of contaminants. <br />
