• NJPDES permit compliance assistance. Completed a statistical analysis of groundwater analytical data samples to identify statistically significant increases of targeted analytes in monitoring wells downgradient of the landfill over background concentrations. The analysis was completed in accordance with the requirements of a Groundwater Protection Program Plan (GWPP) prepared pursuant to 40 CFR 258.
• NJPDES permit compliance assistance. Performed a statistical analysis on stormwater analytical data associated with detention basins.
• Contract administration associated with refurbishment of landfill gas flare that included replacement of flare burner assembly, replacement of thermocouples, re-insulation of flare stack, and stack surface preparation/painting.
