Verifying LNAPL Plume Stability
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
