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 Environmental Services, Inc. is pleased to announce it has been awarded a Multiple Award Environmental Services (MAES) contract with the U.S. Army Corps of Engineers (USACE)–Baltimore District. This contract has a 5-year term, with a maximum total shared contract value of $230 million to be executed among the 10 selected contractors. Task orders under the contract will support USACE–Baltimore District and its customers primarily at locations across the USACE’s North Atlantic Division with incidental use in CONUS, Alaska and Puerto Rico. Services to be provided under this contract may include a wide range of environmental services for hazardous, toxic, radioactive waste as well as support for munitions constituents as well as other explosives of concern.
KEMRON was an incumbent on this contract having been awarded multiple task orders under the previous contract to include work at Fort Detrick, Lone Star Army Ammunition Plant, Fort Pickett and the former Water Reed Medical Center.
“The MAES contract allows us to continue our work in support of the Baltimore District’s environmental mission,” said John M. Dwyer, President. “We’ve assigned a qualified team of environmental professionals to lead this contract, including the Program Manager Marilyn Zumbro.”
KEMRON is proud to support Mississippi Power’s Renew Our Rivers program through the volunteering of our employees! We thank our employees for their hard work and dedication during their off-time to help with the clean up of both the Pascagoula River and Gulfport Lake. The program is one of the state’s premiere, national award-winning environmental stewardship programs. These efforts partner corporate, national, regional and community volunteers to help make and keep our waterways in Southeast Mississippi healthy.

KEMRON is pleased to announcement that it has been awarded a fixed-price task order for the Mississippi Phosphate Superfund site in MS. The scope is for construction of the Phase 1A cap, which focuses on the closure of the western slope of the East Gypsum Stack (EGS). Closure activities include grading of side slopes, benching, and installation of the downslope channels; and placing geomembrane cover; access road construction (~3200 LF); and temporary storm drainage culvert installation. Since 2017 under a separate task order, KEMRON, with a staff of approximately 35, has operated the wastewater treatment facility treating almost 3 billion gallons of water. KEMRON has also been responsible for maintaining the structural integrity of miles of dikes and levees that are used to contain and treat water at the 1500-acre facility. With this new task order, KEMRON’s on-site staff increased to 60 employees.
