7 Steps for a High-Resolution LNAPL Conceptual Site Model (LCSM)

Posted by John Sohl on Dec 27, 2017 12:11:17 PM

So, you’ve decided that a high-resolution 3D assessment of your site would help clear up the uncertainty in where any residual product is hiding and what its spatial relationship is to the soil permeability and the installed monitoring and recovery wells.  How do you get started?

Multiple organizations including U.S. EPA (www.epa.gov/ust), ASTM International (astm.org), the Interstate Training and Regulatory Council (ITRC.org), the American Petroleum Institute (API.org), the Australian Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRCCare.com), and the individual state jurisdictions all have published guidelines for undertaking a systematic assessment of petroleum contaminated sites. 

Turns out, you probably have a lot of important information readily available to get started.  Your key to success going forward will be both a systematic review of where your current LCSM stands to identify data gaps and uncertainties followed by a systematic data collection effort to close those data gaps with multiple lines of evidence.

6 Reasons For High-Resolution Characterization of Your UST Site

Posted by John Sohl on Dec 18, 2017 10:15:00 AM

The EPA's Office of Underground Storage Tanks (OUST) reports the number of cases of Leaking Underground Storage Tanks remaining unresolved exceeds 70,000 across the U.S. The EPA data also indicates the average cost of cleanup as US$130,000.  As with any data, it's important to look at the distribution of data, not just averages.  A vivid (maybe too vivid) example of this “flaw of statistics” is the fact that the average age of diaper wearer is somewhere near middle age, let’s say 45 years old.  Drilling down into the data available from individual state UST cleanup funds, we find many examples of cleanup costs exceeding US$1.0M, sometimes with no end in sight.  We can reasonably infer from the OUST data that the less complex sites have been resolved at a lower cost of cleanup, leaving the more complex sites yet to be addressed.  This begs the question – WHY?

Tracking Diffuse TCE Plumes with Low-Level MIP - Webinar Available

Posted by John Sohl on Aug 16, 2017 3:17:20 PM

 Mature groundwater plumes for environmental contaminants pose a complex challenge with regards to accurate delineation of sources, vertical and lateral extent, dominant pathways, and likely storage zones for residual contaminants.  It is not uncommon for plumes from multiple sources to commingle and diffuse across a relatively large distance and a varied hydrogeological spatial volume. As a result, uncertainty in the accuracy of the conceptual site model (CSM) increases, and in turn the associated risk assessment, and the costs contemplated for cleanup alternatives.  Better data resolution and scale are required to reduce these uncertainties.  Low-Level Membrane Interface Probe Technology with Hydraulic Profiling (HPT) provides one approach for obtaining cost-effective and reliable high-resolution data, at a more informative scale in order to improves CSMs and enable better decision-making.

High-Resolution LNAPL Assessment at Persistent Former Retail Station

Posted by John Sohl on May 23, 2017 1:11:35 PM

COLLABORATIVE TEAM EFFORT HELPS MONETIZE THE COST OF LNAPL CLEANUP FOR TDEC

COLUMBIA Technologies was selected by PM Environmental to support a high-resolution assessment of a former retail gas station with persistent LNAPL contamination.  The goal of the assessment was to evaluate for the Tennessee Department of Environment & Conservation the impact of better information on monetizing the cost of long-term correctives action at these types of sites.  The site is one of 246 remaining "difficult to resolve" sites in Tennessee and is typical of the many of over 16,000 remaining Leaking Underground Storage Tank sites in the U.S.  The project involved a careful review of historical documents, cleanup activities, and extended field activities after hours and at night.   

Detailed information gained through this effort delineated an extensive amount of residual gasoline within difficult soil conditions highlighting the need for careful consideration of remedial alternatives.  The team employed the guidelines of the ITRC Technical and Regulatory Guidance for Evaluating LNAPL Remedial Technologies for Achieving Project Goals.

Should Site Assessments Be Conducted Through Traditional Sampling, Groundwater Monitoring Wells, or Direct Sensing Methods?

Posted by John Sohl on May 16, 2016 10:15:10 PM

 It is safe to say that 99% of all site assessments are either conducted through traditional sampling, groundwater monitoring wells, or direct sensing methods. As a leading site investigation partner to environmental consultants throughout North America and Hawaii, COLUMBIA Technologies specializes in soil and groundwater contamination assessments.

Since 1999, we have completed over 750 site assessments for some of the most discriminating clients including oil companies, government agencies, commercial real estate owners, developers, as well as architectural and engineering firms. Throughout all of our testing and experiences to date, we believe that using a comprehensive High Resolution Vertical Profiling approach seems to be the most cost-effective and accurate method to assess a contaminated site. This consists of direct sensing technologies to delineate the vertical and horizontal extent of the contamination to pinpoint the location. Once this information is known, following up with confirmation soil and groundwater samples would take place to validate the contaminant of concern.

The direct sensing technologies may cost more up front, however they assure that accurate information is being collected to move forward with designing remediation plans. In addition, our patented real-time data services platform, SmartData Solutions®, is able to produce high resolution visualizations through a secured website for online review of project data.
