Southeastern Wood Preserving Site
The Southeastern Wood Preserving site conducted wood-treating operations from 1928 to 1979. Wood treating operations utilized coal tar, creosote and pentachlorophenol as wood preservatives. The EPA listed the site on the Superfund program’s National Priorities List (NPL) in March 2012 and worked with the Mississippi Department of Environmental Quality (MDEQ) to investigate site conditions […]
DOE Oak Ridge Environmental Management Disposal Facility (EMDF)
Project Overview The Environmental Management Disposal Facility (EMDF) is a cornerstone project for the Oak Ridge Reservation, designed to provide the waste disposal capacity necessary to continue large-scale cleanup at the Y-12 National Security Complex and the Oak Ridge National Laboratory. Strategically located within the Bear Creek watershed, the facility’s design is guided by watershed hydrology, groundwater dynamics, and long-term closure […]
Colton Landfill
Project Overview A landfill site in Southern California faced numerous challenges in its closure process. The site was soil-deficient, with only one road available for access. Importing the large volumes of soil typically required for traditional vegetated cover systems posed significant financial and logistical burdens. Additionally, the landfill’s steep 2H:1V slopes created concerns regarding long-term […]
Kpone Landfill Closure

Because of its geographic […]
Newton County Landfill
In 2016, the Newton County Landfill received funding which applied the benefits of ClosureTurf for repair of landfill slopes, mitigation to prevent future leachate issues, and reduced post-closure maintenance. The project was funded by FEMA as a hazard mitigation project in response to leachate seeps and slope erosion and a GEFA Georgia Fund Loan. The […]
Baldwin County Landfill
The Baldwin County Landfill marks a historical final closure as not only the first of its kind in the state of Georgia, but one of the first in the country to feature an entirely new landfill design process utilizing the ClosureTurf® system. Featuring an innovative benchless design, the system eliminated the need for diversion berms, […]
Saufley Field Landfill
Saufley Field Landfill marked the first deployment of ClosureTurf® in Florida, where the system had not previously been permitted or constructed. Today, it demonstrates one of the cleanest, easy-to-maintain closure sites in the state, even after several large weather events. In 2008, Saufley Landfill was abandoned by its previous owner. Prior to the abandonment of […]
South Hilo Landfill
In 2019, South Hilo Landfill reached its capacity. Having been established in the 1960s, the more than 50 year old landfill contained a total of 3,208,204 tons of refuse. The closure of the landfill had been a long time coming. The last load of rubbish was deposited in the landfill in December 2019, but the […]
MIRA Hartford Landfill
Owned by the Materials Innovation and Recycling Authority (MIRA), the state-of-the-art 39-acre and one megawatt Solar Electricity Generating Facility (Solar EGF) is the first in Connecticut to use the ClosureTurf® system and the first to generate solar power. ClosureTurf was chosen as the final cap system because of numerous environmental benefits, including having only 18% […]
EPA Mississippi Phosphates
Mississippi Phosphates, a former diammonium phosphate fertilizer plant in Pascagoula, MS, ceased operations in December 2014 following bankruptcy, leaving more than 700,000,000 gallons of acidic, nutrient-rich wastewater behind. Because of environmental impacts to the community, the EPA, who inherited the site in 2017, was on a mission to close the deemed superfund site as quickly […]
City of Portola Landfill
The Portola Class III landfill is located approximately 1.5 miles northeast of the City of Portola. The landfill was an unlined landfill with highly erosive soils on site causing long-term maintenance issues and ground water contamination problems. When the city began the closure process, they began looking at options outside of the traditional Subtitle D […]
Lemons Sanitary Landfill
Lemons Sanitary Landfill is the first approved final closure in Missouri to use ClosureTurf®. The site struggled with availability and quality of soil to close with a traditional vegetative cap. Because ClosureTurf requires no soil to close, it reduced the number of truckloads required to bring in soil and reduced the over carbon footprint. It […]
Timber Ridge Landfill
In December 2010, Progressive Waste Solutions (formerly IESI-BFI Canada) installed ClosureTurf® on ten acres of its Timber Ridge Landfill in Richwoods, MO. The installation at Timber Ridge was the second of its kind. It resulted because of the positive experience IESI had with the very first installation of ClosureTurf at the La Salle Grant Landfill […]
Lanchester Landfill
The Lanchester Landfill, owned and operated by Chester County Solid Waste Authority (CCSWA), is located 50 miles east of Harrisburg and 40 miles west of Philadelphia. It provides service to 49 communities in the Chester County area. The site has reached capacity on three different occasions requiring on-going expansions. When the need arose to provide […]
Central Landfill
Central Landfill is a state-of-the-art landfill facility in Johnston, Rhode Island, that provides disposal service to about 97% of the state’s residents.
