Groundwater sampling tool for accurate measurement of harmful aquifer sand and groundwater contaminants

Summary: Alexander van Geen, Ph.D.

Technology Benefits: Pristine sample collection from a single extraction sight provides insight to the origin of aquifer contamination.Peltier effect may freeze samples in under 6 minutes allows for improved process control and improved core acquisition rates.Deployable on a variety of platforms, facilitation its incorporation into already available equipment.Screw-on cutting tip of high alloy steel prevents damage associated with normal coring tips, thus preserving rock/water arrangement.Patent information:Patent Pending

Technology Application: Aquifer sampling to increase the safety of drinking water sources in developing countries.Collection of deep ocean sediment samples for oil exploration.Sediment and groundwater sampling in sites of natural gas exploration (e.g., hydraulic fracturing).Exploration of oil sands petroleum deposits.
