PROGRESS REPORT <br />Project: EIS Review for Proposed Landfill Site G in Lake Elmo <br />Project #: 5175.001 <br />Date: March 19, 1991 <br />Reporting Period: 1/26/91 - 2/25/91 <br />Activities Undertaken Durinq the Reportinq Period <br />During the reporting period (January 26 - February 25, 1991) DPRA reviewed <br />existing research literature to determine "typical" municipal landfill <br />leachate constituent concentrations for use in landfill release and ground- <br />water modelling. Technical assistance was provided to Holly Glovatsky of <br />Colle & McVoy Public Relations in the development of the Lake Elmo landfill <br />siting video. Site maps and photographs were provided and discussions held <br />regarding the significant environmental conditions at Site G. In addition, a <br />meeting with Kelton Barr of Geraghty & Miller was conducted on February 25 to <br />discuss their progress on the groundwater modelling task, review preliminary <br />results, and coordinate modelling activities. Subcontractor labor and expen- <br />ses for December are included on this invoice. During that time period, <br />Geraghty and Miller continued their groundwater modelling analysis of hydro - <br />geologic conditions at Site G. <br />Activities Anticipated Next Month <br />Fletcher Driscoll of Geraghty & Miller will provide expert testimony on Site <br />G hydrogeologic conditions during an on -camera interview for a video being <br />produced on the landfill siting process. A final list of leachate consti- <br />tuent concentrations will be compiled and incorporated in DPRA's source term <br />model to assess constituent release rates and concentration profiles for <br />input to Geraghty and Miller's groundwater transport model. Initial source <br />term model results are anticipated during the latter half of the month. <br />Changes in Personnel and Schedule <br />No changes in personnel are anticipated. <br />
