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’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.”
