MONITORING WELL INSTALLATION

Enviroprobe's monitoring well installation capabilities include:

  • 2" I.D. monitoring wells to depths of approximately 150 feet

  • 4" I.D. monitoring wells to depths of 100 feet

  • Maximum depth achievable in unconsolidated formations

  • ATV mounted units for optimum site access

The Dando SDC375 is a powerful, fully equipped roto-sonic drill rig. It is track mounted for superior site access and its 50K Sonicor drill head enables Enviroprobe to effectively achieve drilling depths to 150 feet or greater in unconsolidated formations. The SDC375 is also a capable rock coring machine and is a good choice for some rock coring projects.

 

Geoprobe's powerful 6610DTs, 6620DT, 7720DT and 7822DTs provide powerful auger drilling capabilities in small packages. These unit can also be equipped with a 140 lb. drop hammer to provide SPT tests and DPT drilling in remote locations.

 

The Simco EP200 is mounted on a Toro Dingo mini skid-steer. This unit offers excellent off road capabilities where site access is a problem. This combination is a great choice for unique situations where common drill rigs cannot access. In addition to its Direct Push Technology (DPT) drilling capabilities, it can also install 2"monitoring wells.

The Simco highlights consist of:

  • Auger Capabilities To Install 2" Monitoring Well

  • 35" inch wide skid-steer carrier

  • Shallow Concrete Cutting Capabilities

  • Low Overhead Clearance (9')

  • Able to be operated with remote hydraulic powered unit option from 100' away

  • Can be combined with exhaust hose for indoor drilling

2D Electrical Resistivity Profiling

A sinkhole is the result of erosion of the subsurface. When underground water dissolves carbonate bedrock such as limestone, dolomite, or other soluble rock it creates subterranean passages, cavities and caves. This irregular, subsurface rock topography is known as karst. These voids in the bedrock are inclined to sudden surface collapses (sinkholes). Sinkholes can also occur in areas with soft soil, in mining areas, or where some other subsurface disturbance has occurred.

Human activities which accelerate sinkhole formation

  • New development demands for ground-water resources

  • Lowering the water table

  • Changes in surface water flow

  • Increased weight from structures upon the cavernous bedrock.

Locating sinkholes and subsidence without digging, probing, or drilling can be accomplished using non-destructive field surveys. The two main methods for detecting sinkholes are aerial photography and geophysical procedures.

Various geophysical investigation techniques can be used in Karst terrains including ground penetrating radar, electrical conductivity, electrical resistivitymagnetic field, very low frequency measurement (ELF), gravity field recording and seismic velocity measurements.
