Special Meeting-Council <br />A,pri. t ~30,~ 1979. ?age 7 <br /> <br />M. Gallagher - what is the depth of the monitoring wells? <br /> <br />Mr. Otter 10 to 15 feet below highest known ground water level which is <br />about 32 feet. <br /> <br />M. Gallagher - asked about the well on the northwest side, nitrates now that are <br />traceable in it. <br /> <br />Mr. Otter - recent hydro-geologic tests, passed on ground water flow, there <br />were some nitrates in the well. The ground water flow~to the southwest <br />gradient and it can be affected by several different things. <br /> <br />M. Gallagher - Is there a big change in this well? <br /> <br />Mr. Otter - He turned this question over to Anoka County and State because they <br />have charted water quality of that well. <br /> <br />Mr. Hutchison - the nitrate that was present iLn that well var!~ed from 3 <br />grams per liter to a high of'20 in January of thl~ year ~ ~n Apr%t 1it was <br />down to 6.8. These wells are ~ins'talted oily for purpose Of'monltor!ng first <br />ground water encountered. The sample comes'r.~ght off the top~ It don~t <br />necessarily mean it is com%ng from'the landf~ll~ Sulfer~n the well system <br />creates a routine egg smell. <br /> <br />Mr. Sha - suggests disinfecti.ng the well once a year t0 get r~d of the black <br />water. <br /> <br />Mr. Hutchison -this problem doesn't necessari]S have to D.e'related to the <br />landfill ~t can even be found in munici?al ~_ells. <br /> <br />M. Gallagher - asked if the swamps ~ere tested? <br /> <br />Mr. Knudson (DNR) said he d~d not test the swamp~ but pCA may have tested <br />wetland areas. He has observed ~oodduck~ and Mallard on swamps nearest the <br />landfill. <br /> <br />Mr. Hutchison - data was given to Mr. Sba, so many th_~ngs that can happen to the <br />swamp unrelated to the landfill~ every' year there h~s been at least one <br />family of ducks there, he never saw a dead duck~ <br /> <br />M. Gallagher - asked if they could request that the s~amps be tested at least <br />once a year. <br /> <br />Mr. Knudson said the swamps get runoff from places ot~er than the landf%ll <br />and if there was any pollution they would have to find where it's com?ng <br />from, but it is a good idea to check_ it periodically. <br /> <br />The citizens did not feel enough, testi.ng is being done, there are contaminates <br />that could filter into the water systems. <br /> <br />Mr. Otter - there are two ground water lisymeters test tubes in the ground to <br />determine what would be leaching through the ground. These have been concerns <br />of the regulatory agencies. <br /> <br /> <br />
