Project:   Railroad Embankment Fire Assessment
Location:   Fulton, Kentucky
Client Type:   Railroad

CEG personnel were involved in a project which advanced numerous borings within an active railroad bridge approach to assess the effects of a recent brush fire on the materials used to construct the approach.  CEG personnel determined the lateral and vertical extent of the embankment which was effected by the fire and identified areas which remained as “hot spots”.  Additional borings were advanced along the perimeter of the “hot spots” and were filled with high solids bentonite grout in an effort minimize the potential for spreading and re-ignition of the smoldering areas.

Project:   Peizometer, Observation Well, and Slope Inclinometer Installation
Location:   Grand Rivers, Kentucky
Client Type:   General Contractor/U.S. Army Corps of Engineers

CEG personnel were involved in the installation of several piezometers, groundwater observation wells, and slope inclinometers in support of a highway construction project adjacent to a U.S. Army Corps of Engineers (USACE) dam.  All work was performed in accordance with USACE specifications and under direct USACE and material manufacturer’s supervision.

Project:   Monitoring Well Installation - Property Transaction Assessment
Location:  Fulton, Kentucky
Client Type:  Consultant

CEG personnel installed in excess of 10 permanent groundwater monitoring wells in support of a Phase II Site Assessment at an active rail yard. Site activities included working in close proximity to, and in some cases on, operational rail lines.

Project:  Geotechnical Investigation – Bridge Construction
Location:   Mars Hill, North Carolina
Client Type:  State D.O.T.

CEG personnel were involved in a geotechnical investigation in support of a bridge construction project over the North Toe River in western North Carolina.  This project included wireline core drilling in excess of 100 feet total depth all with difficult set-ups, including utilization of a skid-mounted drilling rig and angle drilling set-ups.

Project:  Monitoring Well Abandonment – Inactive Solid Waste Facility
Location:  Benton, Kentucky
Client Type:  Municipality

CEG personnel abandoned a cluster of four 4-inch diameter monitoring wells at an inactive solid waste landfill.  Abandonment included removal of the surface completions and protective covers, over-drilling of the well casing using both hollow-stem auger and air-rotary drilling techniques, removing the well casing, and backfilling of the boreholes with high-solids bentonite grout via tremmie pipe.  This project was completed in accordance with Kentucky Division of Waste Management regulations and under the supervision of Kentucky Division of Waste Management inspectors.

Project: Soil Sample Collection/Monitoring Well Installation – Property Transaction Assessment – RCRA (and proposed NPL) Facility
Location:  Joppa, Illinois
Client Type: Industrial

CEG personnel completed a complicated sample collection and well installation plan at an abandoned creosote treating facility.  This includes hollow-stem auger sampling, installation of stainless steel monitoring wells, abandonment of damaged monitoring wells, rehabilitation of existing monitoring wells, and near-surface sampling utilizing hand augers and direct-push technology.

Project:  Monitoring Well Rehabilitation
Location:  Calvert City, Kentucky
Client Type:  Industrial

CEG personnel conducted a rehabilitation project to correct biofouling and sedimentation problems in several monitoring wells at a major chemical production facility.  This included the controlled introduction of acetic acid into the wells, surging and scrubbing of the interior of the casing, sediment removal, re-development and pre and post-project aquifer testing.

Project:   RCRA Facility Investigation – Monitoring Well Installation
Location:  Louisville, Kentucky
Client Type:  Industrial

CEG installed eleven monitoring wells, some in excess of 70 feet total depth, at an active industrial complex.  Project duties included well installation and surface completion in strict accordance with USEPA Region 4 Guidelines, well development, aquifer characterization,  and groundwater sample collection.

Project:   Monitoring Well Installation – Inactive Industrial Dump Site
Location:  Jefferson City, Tennessee
Client Type:  Industrial

CEG personnel installed multiple monitoring wells into a thrust fault zone in support of an on-going assessment of an inactive industrial dump site.  Due to the karst nature of the surrounding topography, including the presence of subterranean caverns and sink holes, several specialized double casing techniques were employed to insure the integrity of the wells while minimizing the potential for contaminant migration along the annular space of the borehole.
