BOS Carbon Substrate Injection

KEMRON’s West Virginia office is in the process of conducting a large scale BOS carbon substrate injection at an active retail petroleum facility in western WV to remediate subsurface petroleum impacts at the facility. BOS injections are being performed using our specially designed high-pressure injection trailer in an attempt to aggressively move the site to No Further Action (NFA) status. Due to the large contaminant footprint, injection activities are being conducted in phases across four (4) separate treatment areas designated as Treatment Areas A through D. A total of 40 injection points were advanced in Treatment Area A. Treatment Area A was located towards the southern portion of the UST basin and encompassed approximately 1,000 square feet (ft2). BOS injection activities are currently underway in Treatment Area B (located east of the dispenser islands in the vicinity of monitoring wells MW-5 and MW-6) which will consist of 100 injection points and encompasses approximately 2,560 ft2, Treatment Area C (located east of the dispensers in the vicinity of monitoring well MW-10) which will consist of 34 injection points and encompasses approximately 845 ft2, and Treatment Area D (located northeast of the dispensers in the vicinity of monitoring well MW-9) which will consist of 39 injection points and encompasses approximately 980 ft2.

BOS injection activities at this facility include the injection of 18,805 lbs of BOS and 14,150 lbs of gypsum into a total of 213 injection points encompassing a total of 5,385 ft2. Kudos to KEMRON Project Manager Abdo Chaber and KEMRON injection crew members Tim Mihal, Christopher Hedrick, Evan Amick and Jac Jensen for their work on this large BOS injection project.
