Soil Conductivity Profiles

EPS was contracted by a nationwide consultant firm to provide soil conductivity investigations at several landfills in central Nebraska. EPS successfully defined landfill cells as well as potential migration pathways for contamination beyond the landfill's outer boundaries. EPS is currently authoring a technical paper explaining the results of these investigations. EPS was contracted by a Nebraska consultant firm to perform a soil conductivity investigation at a manufacturing facility in Omaha. The soil conductivity profile was to provide information concerning migration pathways of chlorinated solvents discovered during a previous investigation. The conductivity profiles were located within glacial till and loess deposits. Confirmation soil samples were collected from zones indicating low conductivity. The soil conductivity profile successfully showed that where conductivity levels were low within the Environmental Priority Service, Inc. soils, the majority of the chlorinated contamination was found. Upon further interpretation of the soil conductivity logs, it was discovered that extensive silt, sand and gravel seams could be easily correlated. EPS was contracted by a Nebraska consultant firm to provide information as to the various soil types at an industrial facility in eastern Nebraska. The soil conductivity information was utilized during the remedial design phase of the project. The data was utilized to determine screen depths within recovery wells as well as soil vapor extraction wells. EPS was contracted by a Wichita consultant firm to perform soil conductivity profiles adjacent and within landfills located in south-central Kansas. The information was utilized to determine groundwater sampling intervals as well as to determine well screen intervals. EPS was contracted by a nationwide consultant firm in conjunction with the Corps of Engineers to perform a soil conductivity investigation at the former Schilling Air Force Base in Salina, Kansas. The conductivity data was utilized to verify soil types as well as potential migration pathways of contaminants EPS was contracted by a Nebraska consulting firm to conduct a soil conductivity investigation at a manufacturing facility in Norfolk, Nebraska. The investigation was utilized to determine bedrock depths as well as potential migration pathways for contaminants. The soil conductivity data was then utilized to determine groundwater sampling depths. EPS was contracted by a nationwide consultant firm to conduct a brine investigation near Conway, Kansas. Several major oil and gas companies were involved in the investigation to determine whether brine contamination had impacted the Equus Beds, a vital water source for central Kansas. Electrical soil conductivity in conjunction with soil sampling, mini-well installation and groundwater collection were utilized in this investigation. EPS was contracted by a Colorado consultant firm to conduct a soil condcutivity investigation at a former refinery in south-central Kansas. Testholes were located throughout the refinery and data was utilized to determine optimal screen intervals for monitoring wells, and to determine soil types below the water table. The soils were successfully identified, and cross-sections drawn. Electrical soil conductivity in conjunction with soil sampling, mini-well installation and groundwater collection were utilized during this investigation. EPS was contracted by a Kansas City consultant firm to conduct a soil and groundwater investigation at a former missile silo site located in central Kansas. Testholes were located throughout the former silo site and along adjacent properties. Electrical soil conductivity in conjunction with soil sampling, mini-well installation and groundwater collection with on-site analysis were utilized during this investigation following strict Corps of Engineers' guidelines. EPS was contracted by a nationwide consultant firm to conduct a soil and groundwater investigation at a former army ammunition plant located in western Missouri. Testholes were located throughout the site. Electrical soil conductivity in conjunction with soil sampling, mini-well installation and groundwater collection with on-site analysis were utilized during this investigation following Corps of Engineers' guidelines. EPS was contracted by a Colorado consulting firm to conduct a soil conductivity investigation at a former manufacturing facility in Abilene, Kansas. The soil conductivity investigation was utilized to determine bedrock depths as well as potential migration pathways for subsurface contaminants. The soil conductivity data was then utilized to determine groundwater sampling depths. EPS was contracted by a nationwide consulting firm in conjunction with the Kansas Department of Health and Environment to conduct a soil conductivity investigation at a grain elevator near Pratt, Kansas. The soil conductivity investigation was utilized to determine bedrock depths as well as potential migration pathways for known fumigants discovered at the site. The soil conductivity data determined groundwater sampling intervals.
