August 28th, 2012

ITRC 2-Day LNAPL Classroom Training in Novi, MI on October 16-17

COLUMBIA Technologies is pleased to sponsor the upcoming ITRC LNAPL Classroom Training course. The Interstate Technology and Regulatory Council (ITRC) is offering a 2-day training class from the ITRC LNAPL team on October 16-17, 2012 in Novi, MI, in cooperation with ITRC state member, Michigan Department of Environmental Quality.

ITRC offers this 2-day classroom training course, based on ITRC’s Technical and Regulatory Guidance document, Evaluating LNAPL Remediation Technologies for Achieving Project Goals (LNAPL-2) to assist environmental practitioners with applying science-based solutions for LNAPL sites. The ITRC guidance was developed through the combined efforts of environmental professionals including state and federal regulators, consultants, industry, and community stakeholders. This 2-day ITRC classroom training led by internationally recognized experts should enable you to: Read the rest of this entry »

John H. Sohl III is founder of Columbia Technologies, a Maryland company that maps underground pollution from large manufacturing facilities, oil terminals, pipelines and military bases. The company is a client of the Baltimore Export Assistance Center.

Barry:  How do you map underground pollution?

Sohl:  Mapping involves deployment of sensor technologies that track leakage and migration of pollutants.  Following analysis by our technicians, customers can make decisions on risk assessment, disposition of the property and proper cleanup actions.  Read the rest of this entry »

Five Steps to Developing Weighted Lines of Evidence During Site Characterization

May 30th, 2012

One of the most critical points to remember when developing a site closure work plan is that it simply costs too much to assess, remediate, and make decisions on information that is incomplete, inaccurate, and too late. Traditional approaches to characterizing subsurface conditions by drilling, soil sampling, and monitoring wells screened over large intervals are too incomplete to accurately deal with site heteregoneity.

Therefore, a high resolution site characterization approach is a more attractive option as it enables projects to move forward with remediation focused activities such as corrective action, free product recovery efforts, and site closure.

Let’s face it, the heterogeneity geology of a site is going to impact the migration of subsurface contamination opposed to the age old myth that it always follows the direction of groundwater. Introduction of the Hydraulic Profiling Tool (HPT) for site investigation and remediation efforts supports contaminant mapping activities to provide a greater understanding of subsurface conditions. By measuring direct pressure response, HPT develops weighted lines of evidence indicating the tight (or loose) grains and low (or high) flow zones in order to determine the migration pathways, remediation injection regions, and placements for monitoring wells. With an integrated Soil Electrical Conductivity (EC) array this tool also defines zones of lower conductivity which allows for the movement of contaminants into the subsurface.

Separate different types of petroleum products identified by LIF-UVOST®

Since 2008, our team at COLUMBIA Technologies has supported site managers in evaluating petroleum contamination at 125 and growing projects using direct sensing or imaging tools. These projects include a wide-range of application from gasoline and diesel fuel retail stations to Superfund sites, as well as petroleum terminals, petroleum storage facilities, pipeline terminals, railyards, oil refineries, complex underground storage tank (UST) sites, military installations, and truck refueling facilities. These sites have spanned across 28 states in the United States including Hawaii, and multiple provinces in Canada. One primary technology deployed at these sites is the Laser Induced Fluorescence, specifically LIF-UVOST® to determine the LNAPL distribution at these facilities. These experiences have provided us with a number of lessons learned about accurately, rapidly, and cost-effectively characterizing these sites using this technology. Read the rest of this entry »
