Talon/LPE provides environmental drilling for government, private, and industrial clients. Talon/LPE has extensive drilling experience in a vast array of drilling conditions utilizing traditional and technical methods. Talon/LPE is licensed to drill in Texas, Oklahoma, New Mexico, Kansas, Colorado and Louisiana. In the ever-changing world of emerging contaminants, we consistently train our staff in every aspect of drilling to ensure quality within all phases of a project, from planning to field execution, through final reporting and closeout. We recognize that drilling is one of the pillars of an accurate conceptual site model and is the first step of intrusive field work that transforms a site from a liability back to an asset through remediation.
Sonic Drilling Technology provides a straight, plumb, and gauge borehole in a time efficient manner while providing a continuous log and high sample quality throughout a boring. In addition, Sonic tooling provides a cased and smaller total diameter borehole which eliminates potential washouts and over generation of waste. This reduction of waste generation lowers waste disposal costs and allows us to continue to strive for more efficient operations with less environmental impact.
AIR ROTARY DRILLING
Air Rotary Drilling uses compressed air as the circulation medium. The drill bit cuts the formation and the air clears the cuttings from the boring.
MUD ROTARY DRILLING
Mud Rotary Drilling utilizes pumped water and/or additives as the circulation medium. The drill bit cuts the formation and the mud clears the cuttings from the boring. The cuttings are separated at the surface from the mud and the mud is recirculated back down into the boring.
HOLLOW STEM AUGER
Hollow Stem Auger uses auger flights to remove cuttings while the bit face allows the insertion of a sample tube to collect representative samples. As the drill bit cuts the formation, the cuttings travel up the spiraled flights of the auger and are removed from the boring. This process is very similar to that of a drill bit and a hand drill. As an alternative to hollow stem auger, solid flight auger may be used in stable formations.
Direct Push uses a hydraulic/pneumatic hammer in conjunction with static force to advance the sampler. These rods create the borings and collect soil samples. Although many manufactures create direct push machines, Talon/LPE utilizes Geoprobe® manufactured machines. Talon/LPE offers track mounted, truck mounted, and skid mounted Geoprobe® platforms for varied access.
The Geoprobe® machines accommodate several sampling tools that can be readily attached to the boring rods in order to collect groundwater samples, soil, and soil-gas samples. They are also utilized to install small diameter wells.
In addition, electronic probes can be readily attached to the steel rods providing the Geoprobe drilling machine with the capability to provide in situ or in-place measurements of subsurface properties on a continuous basis. For example, contaminant distribution via a Membrane Interface Probe, hydraulic characteristics via a Hydraulic Profiling Tool, non-aqueous phase liquid characterization using LIF, DyeLIF, OIP, UVOST,® TarGOST,® or a combination of these tools simultaneously.
MONITORING WELL INSTALLATION
When boring the holes for monitoring well installations, Talon/LPE’s choice of drills and rigs will depend on the subsurface formations and any contaminants present. Talon/LPE ensures that the design and installation of all monitoring wells meet project and client needs and follow legal and regulatory standards.
WATER WELL INSTALLATION
Talon/LPE has the equipment and expertise to drill, install, maintain, and decommission water supply wells. Talon/LPE will ensure adequate permitting, drilling, pump installation, maintenance, and water treatment system installation as well as instruct the final operator in maintenance and use of the water system. Talon/LPE has experience drilling in every major and minor aquifer in the state of Texas.
RECOVERY WELL INSTALLATION
When installing recovery wells, Talon/LPE factors in proper lithologic characterization, well design, and the product being recovered in order to yield maximum product recovery. Talon/LPE’s installation approach includes: correct drilling method, proper installation of screen and casing, selecting the correct size screen slot, filter pack, proper development, and surface completion for site conditions.
