When is environmental drilling needed?
When samples are necessary for the purpose of evaluating an area of suspected contamination, or when remediation wells or borings are required for treatment of groundwater or soil, environmental drilling is needed.
Tilley Environmental Services will help you choose the best method that fits your needs.
Direct-push, or soil probing, is a comparatively simple method where a hollow sample liner is driven by a high-speed hammer to collect soil samples, install groundwater monitoring wells and to install varies remediation data points. Direct push technology is the preferred method advancing through softer unconsolidated formations.
Hollow-stem augering is a drilling technique that utilizes flight-style augers with hollow centers to drill to a desired depth. By periodically driving hollow spoons inside an auger and ahead of the bit, undistributed soil samples are collected. Hollow-stem sampling is the preferred method advancing through tough consolidated formations.
Tilley Environmental Services operates the following drilling methods:
Continues or discrete soil samples with Dual Tube (DT) technology, DT22
4.25” or 6.25” Hollow Stem Augers for the installation of 2” or 4” groundwater and recovery wells, respectively.
Installation of soil gas points with DT22 technology.
Discrete groundwater samples using Screen Point (SP22) sampler system or temporary monitoring well screen in an open bore hole.
