Cen~ers City of Ramsey c/o Lloyd Schnelle 15153 Nowthen Blvd. N.W. Ramsey, Mn. 55303 Dear Mr. Schnelle: June 24, 1983 ~,., .,'i) Reference is made to your correspondence of June 17, 1983 concerning monitoring data at the Anoka Landfill. The nitrate nitrogen increase and pH decrease noted in the April 1983 sampling at well la was a substantial departure from the history pre- sented by this well. For this reason, we have requested that Waste Man- agement have this well resampled. We will forward this new data to you as soon as it is received. The noted changes in nitrate nitrogen at wells la and 3 and pH at well la are unusual but they do not necessarily indicate leachate impact on these wells. Since these are very shallow wells they can be subject to significant and rapid impacts from the infiltration of surface water which can affect the nitrate and pH measurements. If these changes were a result of leachate we would expect a history of continuing nitrate increase or pH decrease which has not occured. We would also expect to see similar changes in some of the other parameters, especially chlorides, if this change represent a leachate impact. Hopefully the resampling data will clarify this matter. We will continue to monitor this and advise you of any significant changes. If you have any questions, please call on me. Yours very truly~, R. M.
