Expediting site investigations using cone penetrometer testing and HydroPunch{reg_sign}
- IT Corp., Martinez, CA (United States)
Expedited site investigations can be implemented by the combined utilization of cone penetrometer testing (CPI) and HydroPunch{reg_sign} (HP) groundwater sampling. Hydrogeologic data obtained from these two methods can be employed to maximize the cost-effectiveness of conducting a site investigation and the design efficiency of a groundwater monitoring system. The use of CPT and HP can reduce the lengthy period of time needed to conduct site investigations, accelerating the corrective action process. CPT can be used to delineate a site stratigraphy and differentiate between aquifer and aquitard materials. The HP is used to collect groundwater samples at depths determined by the CPT. HP sampling provide a single groundwater sample at each location. Information from two to four CPT and HP paired locations can be collected in one day as compared to one to two monitoring wells being installed. CPT and HP provide a clean and less intrusive means of hydrogeologic or environmental investigations, with minimal risk of exposure to subsurface contaminants. Site disturbance and waste generation are minimized; no soil cuttings are generated and only a small hole is created to be sealed with grout. Therefore, a key benefit of using the CPT and HP methods is that few soil or groundwater ``drilling`` products are produced, minimizing disposal, personnel exposure, and cost. With the use of CPT and HP, an effective groundwater monitoring system can be designed. Location of wells and screened interval placements are optimized. Based on an efficient groundwater monitoring system, the characterization of the nature, extent, and rate of migration can be expedited. With adequate characterization, appropriate corrective measures can be identified.
