Re: Additional Requested Information Refuse Hideaway Landfill Site
Dear Ms. Reiner:
us EPA RECORDS CENTER REGION 5
431866
As you requested, I have gathered additional information to assist John Wilson, CH2M-Hill, and you in evaluating existing conditions at the Refuse Hideaway Landfill and the Predesign and Additional Studies Work Plan. The enclosed information relates to:
• Existing source control measures (cap, leachate, and gas extraction systems). • Groundwater quality trends at monitored locations near the landfill.
EXISTING SOURCE CONTROL MEASURES
Information enclosed related to the landfill cap, leachate extraction, and gas extraction systems includes:
• Drawing B3, Leachate and Gas Extraction Well and Gas Probe Locations, from the June 1997 Predesign and Additional Studies Workplan.
• Drawing 15292-Dl, Gas and Leachate Extraction System Layout, Warzyn, November 1991.
• Geologic Cross Sections A-A', B-B', and C-C from the Infield Conditions Report, RMT, January 1988.
• Conceptual Cross Sections A, B, and C, from the Infield Conditions Report, RMT, January 1988.
• Table of leachate heads prior to and including extraction system startup.
The geologic cross sections from the RMT report illusfrate geologic conditions below and around the landfill. The Conceptual Cross Sections A, B, and C all show the landfill and geology along a fourth section line. The conceptual views (A, B, and C) demonsfrate three potential interpretations of the relationship between leachate and groundwater. Comparison of leachate levels from subsequentiy installed gas weUs (summarized on the attached table) will be integrated into these cross sections during preparation of the Additional Studies and Predesign Report.
You will also want to refer to Tables 4-1 through 4-5 of the Remedial Investigation, which includes general data on leachate and landfill gas quality. As stated in the Predesign and Additional Studies Workplan, changes in the volumes and quality of the leachate and landfiU gas since completion of the RI/FS, and ROD may have significantiy reduced the mass flux of contaminants to groundwater.

Serving the World's Environmental Needs
allowing significant improvements to groundwater quality. Evaluation of the effect of source control measures is a key objective of the proposed additional studies.
MONITORING WELL DATA
I have also included tables of historic groundwater monitoring results and log-concentration graphs for wells near the landfill that have been regularly sampled (we will be receiving a copy of the WDNR's data base for all wells within the next several weeks). The graphs showing the log of contaminant concentrations over time allow a visual assessment of first-order concentration reductions. The monitoring wells included are: P17S, P20SR, P21S, P22S, P22D, P27S, and P27D.
Several observations suggest the importance of source confrol for groundwater contaminant concentration reductions, including:
• The wells nearest the landfill and downgradient (P21 and P27) show the greatest rates of reduction in contaminant concenfrations, with the shallower wells at both locations showing the highest rates.
• Well P17, located adjacent to the landfill on the upgradient side also shows a significant rate of contaminant concenfration reduction, although it is located in lower permeability material, which retards the rate at which the effects of source confrol are realized.
• Wells located sidegradient (P20) or at some distance downgradient (P22) have been essentially unaffected by source control measures as evidenced by relatively stable concentrations at these locations.
CLOSING COMMENTS
Please call if you have any questions as you review the enclosed information. We look forward to your comments on the Predesign and Additional Studies Workplan.
Sincerely,

General Notes:
1. Leachate heads greater than 10 ft are shaded. 2. Leachate extraction system started August 13,1991. 3. Leachate head measured directly in well risers GW3 through GW13 on November 21, 1990 and
April 16, 1991; otherwise leachate head measured in 1-in. risers located at each wellhead. 4. NA = Leachate head measurement not available due to unidentified blockage in 1-in. riser pipe.
