Discussion originally posted in the Direct-Sensing Specialists group on LinkedIn, “Ten Reasons/Tips for Using Direct Sensing Tools”

Below is a discussion topic on direct-sensing tools posted by an experienced high resolution site characterization specialist, Roger Lamb. We found this note extremely relevant and thought his comments were particularly insightful.

Guest blog post by Roger Lamb, Principal Scientist at OTEK Australia

Last week I had the opportunity to speak at the Australasian Land and Groundwater Association Forum on Advances in Soil, Groundwater and Gas Sampling Technologies on Contaminated Sites in Melbourne. The goal of my presentation was two-fold: 1) to encourage consultants who have never used Direct-Sensing (DS) tools to give them a try, and 2) to provide technical tips on how to use DS tools to their maximum capability. I presented ten reasons/tips as follows: Read the rest of this entry »

Hydraulic Permeability: The Key to Identifying Contaminant Transport Zones at LNAPL and DNAPL Sites for Remediation-Focused Site Investigations

February 19th, 2013

For the remediation-focused site investigation professional, we believe that hydraulic permeability is no longer an option, but a requirement. As this post will outline, hydraulic permeability is key to identifying contaminant transport zones at LNAPL and DNAPL sites for remediation-focused site investigations. Hydraulic permeability data, which is collected with a Hydraulic Profiling Tool (HPT), enables decision makers to understand contaminant mobility and migration. Today, responsible parties and involved stakeholders are looking for more than just lab results from samples and screened well intervals, and are instead looking for data which enables them to minimize risk, reduce costs, and enhance remediation design efforts.

Below is an example of an HPT log from a site with multiple contaminants at concentrations up to and including NAPL. The combined Membrane Interface Probe-Hydraulic Profiling Tool (MiHpt) was used to delineate the horizontal and vertical extent of contamination and collect hydraulic permeability data simultaneously.

Key takeaways from this log include: Read the rest of this entry »
