Verifying LNAPL Plume Stability

Posted by John Sohl on May 1, 2019 10:57:45 AM

Spring is here!  In addition to springtime blooms and new wildlife it's also conference season.  It's always a pleasure to hear industry leaders advancing our our level of understanding of the complex biosphere tainted with man-made contamination.  This past month I had the pleasure of attending the Fifth International Symposium on Bioremediation and Sustainable Environmental Technologies close to home in Baltimore 2019.  Dr. John Cherry's presentation on what we know compared to what don't know through ignorance was a real eye-opener!  The symposium was also highlighted with an awesome panel speaking on Contaminant Geology.

Last week I had the opportunity to speak at the Alabama Conference on USTs on the lessons learned through high-resolution investigations, and in particular the value of high-resolution soil sampling to isolate the residual LNAPL mass on our more complex and difficult sites.  Several others emphasized the importance of improved characterization before implementation of expensive and most likely financially unsustainable remediation systems. 

ITRC guidance document LNAPL-3: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies refers to several lines of evidence to verify LNAPL plume stability.   Accurately mapping the residual LNAPL and verifying stability are the first steps in building an effective LNAPL conceptual site model.  We were assured by ADEM staff that they hear this message and are supportive of better characterization focused on identifying any residual LNAPL and verifying the LNAPL body is stable. 

At COLUMBIA, our team takes pride in providing industry leading data reports to conduct a remedial optimization study to characterize the problem and identify cost saving alternatives through:

  • High-Resolution LNAPL Assessment
  • Low-Level Diffuse GW Plume Mapping
  • Direct Sensing (MIP, MiHpt, LIF, OIP)
  • Data Management and Visualization
  • Real Time Data & Results on any device

Try our Interactive Project Pricing Calculator!

We'll roll up our sleeves and work alongside you better understand those persistent and complex LNAPL sites.

Non-PFAS Highlights from REMTEC 2019

Posted by John Sohl on Mar 4, 2019 2:33:21 PM

I had the pleasure of attending REMTEC 2019 in Denver last week.  As always it was great to catch up with colleagues and hear about new developments in our industry.  While much of the discussion centered around the looming challenges of PFAS contamination, there were also many valuable presentations related to building reliable conceptual site models.

Most inspiring to me personally are the continuing efforts to systematize the process of sustainably restoring heavily contaminated properties back to useful life.  James Henderson with DuPont Corporate Remediation Group provided the benchmark process in his presentation of Harnessing the Value of Contaminated Lands to Achieve Global Environmental, Social and Economic Transformation.  

A leap forward in horizontal high-resolution was presented by Erik Piatt, with En Rx, and their Vertebrae Horizontal Well  system.  This system enables the practitioner to design the placement of individually isolated  horizontal well screens for monitoring or injection beneath buildings and structures without entry into the facility. 

The value of high-resolution site characterization as a key step in remediation design or an effective diagnostic in performing remedial optimization was highlighted in multiple presentations.  New technologies such of the Hydraulic Profiling Tool (HPT) and the HPT-GW groundwater profiler provide critical data on formation pore pressure to support any planning for fluid recovery or injection.  The HPT can be combined with both the Membrane Interface Probe (MiHpt) or Optical Interface Probe (OIP-HPT) for delineation of storage and transport zones for VOCs and LNAPL.  Call us  (+1-888-344-2704if you would like more information on these tools.

I look forward to meeting new friends and seeing old ones at the upcoming Battelle International Symposium on Bioremediation and Sustainable Environmental Technologies in Baltimore, 15-18 April 2019. 

Shoot me a note    if you're going to attend and let's connect.

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.
