KEMRON Environmental Services was recently awarded a $21M project for consolidating nearly 800K CY of slag/source material into a 35-acre on-site containment cell at the Old American Zinc Plant in Fairmont City, Illinois.
We are excited to work for USACE St. Louis District under our PRAC contract. Special thanks to Tom Thrower and Terry Lemasters for leading the proposal effort.
We are pleased to announce that KEMRON was recently awarded a PFAS sampling program at eight Army Reserve installations throughout the state of Georgia.
Congratulations to our Atlanta office for securing this award.

We’re proud ot announce that KEMRON was awarded a $4.4M abatement/demolition project at the former Cristex Drum Superfund site in Oxford, NC under our EPA Region 4 ERRS contract in July 2023.
The scope also includes the excavation and disposal of 20,000 CY of contaminated soils.
KEMRON-Arrowhead JV was awarded the Velsicol Superfund Site Remedial Action Task Order in May 2023, and the $55M award represents a continuation of KEMRON’s work at this highly complex site.
With over 200,000 drums of solvents and pesticides buried in unlined trenches, the selected remedy of vapor extraction and treatment is expected to operate for 12 years.

KEMRON Environmental Services was awarded two new task orders in March 2023 through EPA Region 2 under our Emergency and Rapid Response Services Contract.
The first order is for the cleanup at Compounders Inc. in New Jersey where a fire occurred leaving damaged drums, containers and other waste. At this point, KEMRON is providing security to safeguard the site and is assisting the EPA to develop a strategy to safely handle and address the drums of waste and their contents.
The second task order is for the cleanup of the Arsenic Waste site in New York, which includes the demolition of five residences including all ancillary tanks, piping, systems, etc.
KEMRON was awarded a project to package and remove approximately 575 containers of various sizes including lab packs, drums and vats from the Deptford Plating Site in Deptford, NJ under our EPA Region 2 ERRS contract.
Many of the containers are filled with hazardous substances associated with the plating wastes which included, acids, bases, cyanide, hexavalent chromium, cadmium, silver, lead, and various other metals.
In the fall of 2022, Leisnoi-KEMRON JV was awarded two projects through the USACE Fort Worth District to provide Programmatic Environmental Assessments (PEA) at 15 Army installations to support decisions on locating future weapons systems.
The PEAs will be performed pursuant to the National Environmental Policy Act and will include an analysis of baseline cultural and natural resources conditions and an evaluation of any environmental impacts.
Thank you to Edwards-Pitman, who will be our primary subcontractor.
In October 2022, KEMRON was awarded a subcontract through our 8(a) Protégé, Leisnoi, to install two extensions to the existing Permeable Reactive Barrier (PRB) Walls at Red River Army Depot (RRAD). These extensions will improve the performance of the PRB walls installed by KEMRON in 2007.
The PRB will be installed using long-reach excavators and will require hand excavation around several live utilities. KEMRON will also conduct performance groundwater monitoring in conjunction with the ongoing compliance groundwater monitoring program at RRAD.
Congratulations to Marilyn Zumbro for continuing to expand KEMRON’s work at RRAD.
In September 2022, KEMRON was pleased to receive the award of the $3.1M remedial action project at the former Smokey Mountain Smelters Site in Knoxville, TN.
KEMRON will consolidate existing waste on-site, install a geocomposite cap (comprised of a GCL and 60 mil HDPE liner) over the waste, and perform 2 rounds of injections to adjust geochemistry to oxidize/immobilize metals in groundwater.
In August 2022, KEMRON was awarded the $88.5M St. Louis Pre-placed Remedial Action Contract (PRAC) for projects in the Mississippi Valley Division (MVD) and for EPA Regions 5 and 7.
This contract will allow KEMRON to expand our ever-growing capabilities within the MVD and the Midwest.
KEMRON was contracted by the Crisp County Power Commission to close a coal combustion residuals (CCR) pond in Warwick, Georgia. KEMRON prepared an Erosion Sedimentation and Pollution Control Plan that was submitted to the Local Issuing Authority and approved for a Notice of Intent for construction. Best Management Practice (BMPs) for stormwater management in the form of over 3,000 linear feet of double row silt fencing and a sedimentation basin were installed. KEMRON implemented fugitive dust control in the form of dust suppression by maintaining appropriate moisture levels, dust control by spraying of water as the dryness of the CCR/soil material warranted and Onsite monitoring of dust levels.
Initially, 10 acres of organic content was removed from the surface material within pond. Once the stripping operations were complete, the area inside the ash pond was prepared inside the pond to spread out wet/saturated CCR and allow it to decant, evaporate, and dry. A blending area and a ready to load out stockpile area was prepared. Onsite paint filter testing was conducted of CCR and blended materials prior to load out and disposal to ensure that material was within compliance for landfilling. Once materials met disposal criteria, they were transported for off-site disposal at the Crisp County MSW landfill. Over 117,000 cubic yards of CCR has been excavated and disposed followed by backfilling over 20,00 cubic yards of clean backfill for site restoration. Project activities included 12,000-man hours without a recordable incident.
KEMRON designed and implemented a wastewater treatment system (WWTS) to treat contact water pumped from the ash pond prior to discharge to the Flint River in compliance with Georgia Environmental Protection Division NPDES Discharge Permit. The WWTS consisted of: 42,000-gallon weir/equalization/sludge tanks; 800-gallons per minute suction and discharge pumps; 23 Bag Filtration Units; pH adjustment unit; 42,000-gallon effluent tanks; Coagulant/flocculent mix system; flow meters; static mixer and static mixer injection manifold; and aluminum chloride hydroxide sulfate flocculant mix. Water samples were collected from the effluent sampling point on a weekly basis and from the Flint River and tested. Effluent and instream monitoring results were submitted to the GA EPD through an online submittal system each month following the sampling period in accordance with the NPDES Permit.
