HPT Webinar: Using HPT Logs for Site Characterization
Recorded March 28th 2013
The HPT is a direct push tool that produces a hydrostratigraphic log by measuring the response of soil to the injection of water as the HPT probe is advanced in the soil. HPT usage for site characterization has been growing both as a stand-alone logging tool and as an add-on tool to MIP. Geoprobe Systems® Geologist Wes McCall has many years of experience working with the HPT logging system. Wes will start this webinar with the principles of operation of the HPT, show special functions such as hydrostatic measurements and K estimations, and then show example logs from a variety of geologic settings. This training webinar will be useful to consultants and regulators who specify the usage of HPT logging on their sites and for field operators of HPT tools.
LL MIP Webinar: An Introduction to the new LL MIP (Low Level Membrane Interface Probe) Probe Technology
Recorded April 30th 2013
Presented by Thomas M. Christy, PE, Vice President of Geoprobe Systems® and Dan Pipp, Geoprobe® Chemist.
The MIP direct-push tool for logging VOC contamination has been in use for site investigation for more than 15 years. MIP technology is now widely used for site characterization in the U.S. and Europe and is growing in usage in Australia, and parts of Asia and South America.
This seminar will introduce our latest development in MIP technology; the Low Level system (LL MIP). The LL MIP is a gas flow control system adaptable to most existing MIP systems. Application of this system typically results in an order of magnitude increase in the sensitivity of a standard MIP system. This increased sensitivity (reduction in detection limit) will greatly broaden the number of sites where MIP can be applied.
This webinar will describe the operational theory of Low Level MIP and will describe the altered gas flow control system of Low Level MIP along with the practical aspects of setting up and applying this system in the field. Example Low Level MIP logs from contaminated sites will be shown and compared with standard MIP logs. Case studies will also be shown comparing Low Level MIP measurements with co-located groundwater samples at VOC contaminated sites.
