BOS 200® Defeats BTEX at Truck Stop

Shield Environmental Assoc. Defeats BedrockContamination with BOS 200® at Truck Stop

Shield Environmental Associates (Lexington, KY) has faced some daunting challenges over many years of successful service to their clients, but this one was remarkable.

The Problem: A 320 foot long dissolved BTEX plume in both shallow and deep zones in lithology very unfriendly to direct push sampling or injections.

The Team: Shield Environmental Associates and RPI Group affiliates AST Environmental(Midway, KY) and The Well Improvement Company (Fort Collins, CO).

The Solution: Air rotary drilling, “one of a kind” specialized straddle packer for discrete sampling and precision injections, electric resistivity imaging survey, geophysical logging, discrete groundwater sampling and high pressure/high flow injections of Trap & Treat® BOS 200® based on a thorough Remediation Design Characterization (RDC).

The Result: No Further Action (NFA) letter issued on Feburary 27, 2015 by the Kentucky Underground Storage Tank Branch. The compliance wells have been below the target criteria (< 400ppb BTEX) for 4 quarters. Further note, with the exception of one well, the wells have all been < 5ppb during the same time period.

The project leader, Mark Sweet, President of Shield Environmental Associates said“Application of BOS 200® at this site resulted in a remedial solution to a historically challenging site. It was the right solution to address the impacts in view of the complex geological setting posed by the site!”
