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.

KEMRON would like to recognize and congratulate its Safety Light Superfund Site Team on a HUGE safety achievement! The team has worked more than 114,000 hours without an OSHA recordable or incident. This includes approximately 41,500 hours for radiation subcontractors on site and the removal and transport of 1800 loads of radioactive material. This strong safety record over the course of six years demonstrates the Safety Light crew’s dedication and commitment to the protection of worker safety on this very complicated project. KEMRON thanks the Safety Light Team – Dave Tiedman, Heather Garrison, Dan Jones, Guy Smith and Zach Smith. Safety Light is a $29M radiological ongoing cleanup under a contract with EPA Region 3.

KEMRON, under contract to USEPA, reengineered the water treatment process at the Mississippi Phosphate Corporation Superfund Site to accelerate treatment and maximize throughput. Water management volumes from low pH (<2) leachate and rainfall coming in contact with the gypsum stacks on this 400 acre site exceeds 1.5 billion gallons since KEMRON took over management. One inch of rain fall generates 9 million gallons of low pH contact water. The existing treatment process was able to effectively treat 1.5 million gallons a day. Through a series of modifications to include construction of mixing and settling ponds, KEMRON increased the treatment capacity to 4 million gallons per day.
KEMRON further reengineered the treatment process by installing an in-line mixing operation that introduces spent lime slurry from the mechanical plant into the low pH water before piping the lime slurry three miles to a series of mixing and settling ponds. This provided a marked improvement to pH adjustment through a much shorter treatment time frame further increasing overall efficiency by 20%. Cost savings in reduced quick lime are $22,000 per month. Savings on total treatment costs are in excess of $2.5M per year.
