Services Provided

• Black Oak Landfill horizontal expansion engineering, design and permitting.
• CML Cell 6 sump investigation in support of engineering services to determining groundwater level and engineering design implications.
• Perform semi-annual groundwater sampling, statistical analysis, and reporting for multiple landfills throughout the Midwest.
• Conduct background quarterly monitoring for new network wells and perform statistical analysis at multiple landfills to evaluate data quality and representativeness.
• Prepare Assessment of Corrective Measures reports and well installation work plans.
• Perform proactive geochemical analysis for monitoring wells showing statistical exceedances comparing leachate analytical and surface water analytical to well data.
• Prepared work plans, executed fieldwork, and prepared final reports for two investigations into volatile organic compound detections in groundwater. Fieldwork included collection of groundwater, leachate, and SUMMA cannister air samples.
• Prepared an Assessment of Corrective Measures and Selection of Remedy resulting in the design and installation of a passive landfill gas cutoff trench.
• Preparation of stormwater and leachate management plans.
• Designed and installed a groundwater monitoring network including analysis of lithological and hydrogeological site conditions. Borings were logged and field interpretations made in order to properly screen monitoring wells in a low-yield aquifer.
