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, 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.

Don Rigger is the most recent addition to the KEMRON team in the role of Program Manager. Don joins KEMRON from EPA Region 4 after a 31-year career in the Superfund program. For his first 12 years at EPA, Don served as an On-Scene Coordinator (OSC) in the Emergency Response program where he managed removal actions and responded to environmental emergencies. After a few years in a supervisory role in Emergency Response, Don transitioned to a program management role in the Region 4 Superfund Remedial program. In that role, Don had two primary management responsibilities: Region 4’s site assessment program which adds new sites to the National Priorities List (NPL), and Region 4’s remedial program which investigates and remediates NPL sites across the Southeast.
Don’s project management portfolio as an OSC includes the Jackson County Pesticide Site in the late 1990’s which was, at that time, the most expensive removal action in the history of EPA’s Superfund program. Under Don’s leadership, Region 4’s remedial program built a strong reputation for moving sites quickly and cost effectively through the Superfund pipeline from Remedial Investigation to cleanup completion.
Prior to joining EPA, Don served brief stints in the oil/gas exploration business and geotechnical consulting. He hold a BS degree in geology from Washington and Lee University and an MBA from Georgia State.

KEMRON, under a five year, $85M task order under the Huntsville WERS contract is conducting multiple studies of Advanced Geophysical Classification system application at Fort Ord, California under a task order with the USACE Sacramento. The following information is a brief update on the findings and conclusions of recent and ongoing activities.
The Munitions with Sensitive Fuzes Field Study conducted at Range 48 at Fort Ord was designed to compare the performance of the Geonics EM61 and the White River Technologies OPTEMA Advanced Geophysical Classification (AGC) system for locating 40mm HE projectiles in the near subsurface (0-12 inches bgs). DGM detection surveys were conducted with both the OPTEMA and EM61, and all detection targets were intrusively investigated to provide ground truth for the field study. The OPTEMA sensor was used in dynamic mode with dynamic data being used for anomaly detection. The detected target locations were then analyzed to classify the anomaly sources as targets of interest (TOI), which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. Detection targets not selected by the OPTEMA sensor but located by the EM61 were added to the OPTEMA target list to compile the final detection target list. Although a total of 11 acres were geophysically surveyed, because the anomaly density was found to be extremely high (2499 anomalies per acre) the area of investigation was subdivided into three (3) 25’x25’ grids that were used for the field study. A total of 412 DGM anomalies were selected as initial detection targets in these 3 grids. The dynamic OPTEMA AGC sensor data was then used to reduce the number of detection targets from 412 to 129 TOI. This is a 68.7% reduction in the number of targets that would need to be excavated in a production (non-field study) investigation. Of these 129 anomalies classified as potential TOI, a total of 44 MEC or MEC-like (inert) items were located.
The Munitions with Sensitive Fuzes Field Study conducted at Unit 23 at Fort Ord was designed to compare the performance of the Geonics EM61 and the Geometrics MetalMapper 2×2 (MM2x2) AGC system for locating 40mm HE projectiles in the near subsurface (0-12 inches bgs). DGM detection surveys were conducted with both the MM2x2 and EM61, and all detection targets were intrusively investigated to provide ground truth for the field study. The MM2x2 was used in both dynamic and cued mode, with dynamic data being used for initial anomaly detection. Cued MM2x2 measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. Detection targets not selected by the MM2x2 sensor but located by the EM61 were added to the MM2x2 target list to compile the final detection target list. A total of 1.1 acres were geophysically surveyed. A total of 1814 DGM anomalies were selected as initial detection targets. The MM2x2 classification analysis reduced the number of detection targets from 1814 to 375 TOI. This is a 79.3% reduction in the number of targets that would need to be excavated in a production (non-field study) investigation. Of these 375 anomalies classified as potential TOI, a total of 3 MEC and 6 MEC-like (inert) items were located.
The Risk Reduction in Units 11 and 12 conducted at Fort Ord was designed to remove large ordnance items (155mm and 8” projectiles) from the near subsurface (0-1 ft bgs and 0-2 ft bgs (area dependent)) prior to a controlled burn. This Risk Reduction used both the Geonics EM61 and the Geometrics Metal Mapper (MM) AGC system. The EM61 was used for initial anomaly detection over 468 acres that comprised Units 11 and 12. A total of 4625 anomalies were identified with the EM61 that were indicative of potential large MEC items (155mm and 8” projectiles) in the near subsurface. Cued MM measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. The MM classification analysis reduced the number of targets to be intrusively investigated from 4625 to 589. This is an 87.3% reduction in the number of targets requiring excavation. Of these 589 anomalies classified as potential TOI, a total of 237 MEC and MEC-like (inert) TOI were located. In addition to the recovered TOI, 437 non-TOI munitions items smaller than the risk reduction TOI were recovered from the intrusive investigation locations.
The Risk Reduction in Unit 23 conducted at Fort Ord was designed to remove large ordnance items (155mm and 8” projectiles) from the near subsurface (0-1 ft bgs and 0-2 ft bgs (area dependent)) prior to a controlled burn. This Risk Reduction used both the Geonics EM61 and the Geometrics MM2x2 AGC system. The EM61 was used for initial anomaly detection over 368 acres that comprised Unit 23. A total of 1217 anomalies were identified with the EM61 that were indicative of potential large MEC items (155mm and 8” projectiles) in the near subsurface. Cued MM2x2 measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. The MM2x2 classification analysis reduced the number of targets to be intrusively investigated from 1217 to 242. This is an 80.1% reduction in the number of targets requiring excavation. Intrusive investigation of the 242 anomalies classified as potential TOI is currently scheduled.
The Remedial Action at the area known as Broadway Bypass at Fort Ord was designed to locate and remove all MEC items to depth. This Remedial Action used the TEMTADS AGC sensor in both dynamic and cued mode over a 2 acre area. A total of 5021 detection anomalies were initially identified with the TEMTADS. Cued TEMTADS measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. The TEMTADS classification analysis reduced the number of targets to be intrusively investigated from 5021 to 2175. This is a 56.7% reduction in the number of targets requiring excavation. Of these 2175 anomalies classified as potential TOI a total of 50 MEC and MEC like (inert) items were located.
The Remedial Action at Unit B-2A at Fort Ord was designed to locate and remove 4.2-inch mortars to a depth of 18 inches bgs. This Remedial Action used the Geonics EM61 and the Geometrics MM2x2. The EM61 was used for initial anomaly detection over 73.5 acres that comprise Unit B-2A. A total of 749 anomalies were identified with the EM61 that were indicative of potential 4.2-inch mortars in the near subsurface. Cued MM2x2 measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. The MM2x2 classification analysis reduced the number of targets to be intrusively investigated from 749 to 69. This is a 90.8% reduction in the number of targets requiring excavation. Intrusive investigation of the 69 anomalies classified as potential TOI is in progress.
The Remedial Action at the Vernal Ponds at Fort Ord was designed to locate and remove all MEC items to depth. This Remedial Action used the Geonics EM61 and the Geometrics MM2x2. The EM61 was used for initial anomaly detection over 11 acres that comprised the Vernal Ponds. A total of 1007 anomalies were identified with the EM61 that were indicative of potential subsurface MEC. Cued MM2x2 measurements were then acquired at the detected target locations, and the cued data were analyzed to classify the anomaly sources as TOI, which would require intrusive investigation and removal, or non-TOI, which could be safely left in place. The MM2x2 classification analysis reduced the number of targets to be intrusively investigated from 1007 to 436. This is a 56.6% reduction in the number of targets requiring excavation. Intrusive investigation of the 436 anomalies classified as potential TOI is currently scheduled.
