Remediation Well Applications on Environmental XPRT

Horizontal Remediation Well Systems

Horizontal wells are a proven and effective remedial technology for site cleanup. For environmental applications, horizontal wells offer several advantages in comparison to traditional vertical wells. The first horizontal wells were installed using a mid-sized directional drill rig in 1993 by Directional Technologies, Inc. The three (3) horizontal Soil Vapor Extraction wells installed at John F. Kennedy International Airport was the beginning of a new industry. Directional Technologies, Inc. founders transferred their experience from the oil fields to the environmental industry. This has resulted in the installation of over 1,000 horizontal wells for site remediation worldwide. Horizontal Remediation Wells are a time-tested and proven technology that can provide solutions for problems previously considered unfeasible.

Hazardous waste treatment solutions for site remediation

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 the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

Solutions for the in-situ soil remediation

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 down gradient recovery wells or trenches.

In-Situ Soil & Groundwater Remediation

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 well documented; The process is easily applied and controlled; The treatment occurs rapidly, lasting from a few hours to a few weeks; The process produces no by-product wastestreams, and can be tuned for the degree of contaminant removal desired. This allows it to be used synergistically with other technologies such as biotreatment or soil washing.

Uremediate soil and water remediation of Uranium

Please see files for more information. The following mechanisms of direct bacteria-uranium interactions are described: i) oxidation of U(IV) to U(VI) resulting in solubilization; ii) bioaccumulation, which includes processes of bio-sorption by cell surface iii) reduction of U(VI) to insoluble U(IV); polymers and/or uptake inside the cells. iv) The U(VI) accumulated both on the bacterial surfaces or inside the cells as well as biologically reduced U(IV) precipitates can initiate bio-mineralization processes, which result in immobilization of additional amounts of uranium. v) Dose rate: 300 gm per Ton Biomass (for soil treatment). vi) Dose rate: 100 gm per KL (for water treatment).

Data analysis and visualization tools for monitoring well decommissioning

Contaminated groundwater sites worldwide are engaged in regular sampling of monitoring wells at a typical cost of $1,500 per well-sampling event. On most sites, many wells are redundant or geostatistically insignificant and can be decommissioned.
EVS-PRO and MVS`s Well Decommission module analyses all available data and quantifies the impact on site assessment quality associated with removing each well. The impact of removing a well is quantified in terms of its impact on the geostatistical plume extent.
During remediation plumes are shrinking and may drift. This can necessitate decommissioning of some wells and adding new wells. C Tech`s well decommissioning and DrillGuide© technology provide the tools to properly monitor and guide the remediation efforts at the lowest possible cost.

In-situ Reduction Technology of Groundwater Remediation Industry

In-situ groundwater remediation method is based on injection of Fe(0) nanoparticles through application wells directly into the contaminated water. nZVI injection is very fast, reaching significantly lower operating costs compared to commonly used remediation methods (expensive construction of reactive barriers, building of pump&treat stations, excavation of contaminated soil etc.). In comparison to other in-situ technologies a far lower quantities of injected chemical is needed due to high efficiency of the product and thus the time and cost of remediation is reduced.

Complete Bioremediation of site contaminated with Fraction 2 petroluem hydrocarbons

Delta had been contracted during the 2014 remediation at the well site to apply their bioremediation process to excavated and stockpiled soil contaminated with Fraction 2 petroleum hydrocarbons (F2 PHC). Soil sample results from a 2014 Phase II ESA showed F2 PHC concentrations ranging from 170 mg/kg to 1210 mg/kg, with an average of 586 mg/kg in the four samples from the disposal area. Delta was on the site for around 10 hours using their hopper and amendment sprayer machine to treat the approximately 600 cubic meters of fine–grained contaminated soil. The treated soil was conveyed back into the excavation so the bioremediation process could continue. The client retained Gulo Environmental for sampling of the amended soil piles in May of 2015. Results from the analysis of the samples, taken approximately nine months after the bioremediation process, showed non-detection for F2 PHC, resulting in successful closure of the site.

Waste recovery for construction industry

Construction waste consists of unwanted material produced directly or incidentally by the construction industry. This includes materials that may contain lead, asbestos or other hazardous materials. There is increasing pressure on the construction industry to dispose of this hazardous material in an environmentally responsible manner. Tetronics can help alleviate this pressure by providing waste recovery plants to deal with all types of hazardous wastes generated from a construction projects lifespan: from land remediation through to the treatment of APCs from incineration as well as the treatment of asbestos.

Industrial air pollution control for the recycling and waste management

Due to the continuous rise in the waste volumes worldwide it is essential constantly to seek alternatives to landfills and waste incineration: one suitable approach is bio-mechanical waste treatment. Apart from waste management, applications for air purification systems in this field range from soil remediation to sewage sludge drying in waste water treatment, as well as to the recycling of resources and their possible re-introduction.

Water Treatment Solutions for Uranium Removal

AdEdge provides treatment systems for for Uranium removal using AD92 an anion exchange media that is ideal for use in potable water as well as non-potable and environmental remediation applications for removal of naturally occurring uranium. The high efficiency AD92 can selectively remove the negatively charged uranium anion (most often in the form of uranyl carbonate) to below the existing EPA MCL of 30 ug/L. The AdEdge AD92 systems can deliver the needed performance in two ways: (1) via regeneration type systems which use the media to remove the uranium with periodic regeneration using NaCl brine; or (2) as a “throw away” discardable media, which can be discarded when spent. This option maximizes the very high capacity of the AD92. Where on-site regeneration is not available, this disposal option is the preferred option. Disposal options will vary based on federal, state, and local regulations.
