Helping others clean up the earth by clearing up brownfield remediation odors. Helping others clean up the earth by clearing up brownfield remediation odors. Brownfield remediation consists of removing large amounts of soil that have been saturated with tar, oil or other contaminating substances. Not only dangerous to handle, the disturbed soil is often infused with very unpleasant and in some cases potentially nauseous odors.
Sitelab's UVF-3100D is used to test soil to help investigate and clean up sites contaminated by above ground or underground storage tanks (USTs). Soils can be analyzed for extended diesel range organics (EDRO) or extractable petroleum hydrocarbons (EPH). Results correlate well to confirmatory lab methods.
For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at...
The use of H2O2 to chemically oxidize the contaminants into mineralized products (CO2 , salts, and readily biodegradable organic fragments) offers a number of advantages over these current treatment methods.
Benefits of Soil Decontamination by Chemical Oxidation:
The reagent used (H2O2) is inexpensive, readily available, and has as its reaction products water and oxygen;
The chemistry of the process (Fenton's Reagent) has been known for over 50 years and its applicability to a wide variety of contaminants is...
Several industries and industrial processes may contribute to soil and groundwater contamination. AdEdge Technologies has supplied filtration equipment for several remediation efforts to remove arsenic, lead, and other inorganic contaminants to meet state and federal mandates.
The remediation division of Anguil Environmental Systems (formerly known as Global Technologies) is focused on treating emissions and water contaminants extracted from below the earths` surface. Formed shortly after the 1990 Clean Air Act targeted emissions associated with the extraction of polluted compounds from contaminated sites, Global subsurface remediation equipment has been successfully applied on contaminated sites in North and South America, Europe, Asia and Australia.
The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from...
Characterization of contaminated groundwater requires detailed monitoring to eliminate data gaps, improve predictive numerical models, and track remedial efforts. The Westbay System is a reliable, cost-effective technology for obtaining detailed information, enabling groundwater professionals to carry out comprehensive and defensible contaminant site investigations and long-term monitoring.
Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.
Regenesis Remediation Services (RRS) is a dedicated team of scientists and engineers whose primary function is to provide environmental engineering and consulting firms with specialized groundwater and soil remediation planning, design, verification and application services.
based in San Clemente, CALIFORNIA (USA).
BioSolve Pinkwater is used at major remediation and construction work-sites where excavation of contaminated soils may release noxious organic odors or hazardous VOCs. The dilute solution is sprayed directly onto newly exposed soil surfaces or stockpiles of contaminated material where volatilization is taking place. Used as an alternative to foam, Pinkwater creates a barrier that keeps vapors in the soil, allowing work to continue safely without disruption to workers or neighbors.
Nanoremediation represents a modern method of treatment of environment polluted by chlorinated hydrocarbons, heavy metals, radionuclides and other contaminants. This technology started to be used tentatively in USA and it already takes place on various sites around the world at present.
Toxic hydrocarbons in groundwater can be found dissolved in water diffused over the area. At higher concentrations they can be present as DNAPLs (dense non-aqueous-phase liquids) or LNAPLS (light non-aqueous-phase liquids) creating an enduring source of toxic contaminant supply to the water phase.
Sites with soil contamination often are also subject to contamination of the groundwater. Groundwater contamination can be very complex and a thorough understanding of the geology of the aquifer and contaminant sources is critical in planning remediation efforts. EnterVol offers C Tech’s proven technology within the ArcGIS environment.
Use iSorb at major remediation and construction sites where excavation of contaminated soil or draining of ponds can release unpleasant odors or hazardous VOCs. Spraying a thin-viscosity MioGel onto newly exposed soil or stockpiles of contaminated material keeps vapors in, provides a safe environment for workers, and protects the public from toxic fumes.
The OVT container is an innovative product and a highly effective tool for the preliminary testing of media/soils that have been impacted by a wide variety of volatile organic contaminants of concern (COC’s).
• No preparation or modification needed prior to use in field
• Air tight OVT lid has built in sealed sampling ports of varying sizes to accommodate different size OVA probes.
• Lids snap together so all samples from one well/boring can be easily grouped together.
• Reduced potential for injury to...
