Site Investigation and Assessment

Agrico Chemical The Agrico Chemical site is a 35-acre Superfund site in Pensacola, Florida. The plant began operation in 1889 and produced sulfuric acid, superphosphate, and monosodium phosphate. When the plant closed in 1975, all equipment and buildings were removed. To initiate a Remedial Investigation/Feasibility Study (RI/FS) under EPA oversight, aerial photographs and interviews were…

Streamlined and Innovative Assessment

Specific methods used for expediting complete assessment and to combine assessment with other phases are summarized in the examples below. Earth Systems has used these methods for individual sites of special concern and for a group of sites simultaneously. Special techniques for fast-track project completion won’t work unless the management team rises to the occasion…

Source Removals

Earth Systems is an advocate of using source removal as a primary means of remedial action. When properly implemented, source removal quickly and cost effectively reduces contaminant mass levels. All of the excavations successfully reduced dissolved hydrocarbon levels to below NA Monitoring levels, and most of the source removals resulted in approval of a No…

Soil and Groundwater Remediation

In-Situ Bioremediation-Sages Dry Cleaners Earth Systems is directing cleanup of the Sages Dry Cleaners site under a contract with the Florida Department of Environmental Protection’s Bureau of Waste Cleanup. The site has residual PCE DNAPL and associated dissolved CEs in three zones. Earth Systems recommended and is implementing In-Situ Bioremediation (ISB) that consisted of injecting…

Risk Based Cleanup

Four Georgia Coastal Plain Sites At four contaminated sites in Georgia, Earth Systems derived alternate risk based cleanup levels based on results of a potential receptor survey and analytical, three dimensional, solute transport modeling. The sites are located in the coastal plain with hydrogeology similar to many Florida sites. The potential receptor survey identified points…

Vapor Intrusion

Vapor intrusion is the general term given to migration of hazardous vapors from any subsurface contaminant source, through the vadose zone and into indoor air. Vapor intrusion is widely recognized as a potentially significant cause of human exposure to volatile hazardous chemicals in indoor spaces. Earth Systems, along with one other consulting firm, designed and…

Exploration & Production Support

Brine Release Assessment & Cleanup, Keene, North Dakota Produced brine water leaked from a disposal pipeline and impacted the surrounding soil, groundwater, and nearby creek. Earth Systems used a geophysical survey including Electro-magnetic (EM) and Electrical resistivity (ER) to non-intrusively assess the horizontal and vertical extent of impacts. Geochemical mechanisms prohibiting plant growth at the…
