  • Soil Treatment of Chlordane

    The following graph illustrates the analytical results of a bio-treatability study conducted on MTBE. A two-liter groundwater sample was collected from the client's service station in western Pennsylvania. We tested three different combinations of microbe and nutrient products in order to determine which products are the most effective. The results indicate that MTBE can be bioremediated by our ...

  • In Situ Treatment Technologies for Contaminated Soil

    Compared to excavation and ex situ treatment, the use of these technologies offers several benefits, such as addressing deep contamination and generally costing less. The summary for each in situ technology includes a basic description of the technology, its implementation, applicability based on contaminants and site characteristics, general limitations, costs, and status of the ...

  • Impact of pre-treatment technologies on soil aquifer treatment

    This study investigates the impact of pre-treatment options on the performances of soil columns simulating soil aquifer treatment (SAT). For this purpose a conventional activated sludge (CAS) process, a membrane bioreactor (MBR) and vertical flow reed beds were used as single units or in combination before SAT. The influent and effluent from each treatment train were monitored over three ...

  • Treatment of Oil-Contaminated Soils for Identification and Classification

    An experimental investigation was performed to evaluate the effects of oil contamination on soils and to establish a methodology to identify and classify contaminated soils. Identification and classification tests were performed before treatment, cleaning, stabilization, or disposal of contaminated soils.There are no standards for identification and classification of contaminated soils. ...

  • In Situ Physical/Chemical Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Contaminated soils and sludge treatment plant - Case Study

    Client: Ecosistem Group, Lamezia Terme (CZ) – Italy Challenge: to transform waste into product! The Client possesses a large plant for the treatment of products contaminated with hazardous substances and materials, recycling of recovered materials and disposal of non-recyclable waste, which is considered highly ...

  • Fate of selected pharmaceuticals and their metabolites in soil aquifer treatment

    Through a series of long-term column experiments, the fate of three common pharmaceuticals (carbamazepine (CBZ), diclofenac, and indomethacin) and their major phase I metabolites in soil aquifer treatment (SAT) were monitored. CBZ concentration increased by a factor of two (from 37 to ca. 70 ng/L) regardless of the treatment conditions, and its metabolites, ...

  • Fate of triclocarban during soil aquifer treatment: soil column studies

    There are current concerns about the presence of persistent chemicals in recharge water used in soil aquifer treatment systems. Triclocarban (TCC) has been reported as a persistent, high production volume chemical with the potential to bioaccumulate in the environment. It is also known to have adverse effects such as toxicity and suspected endocrine disruption. This study was carried out to study ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • Bioremediation of ground water by treatment of soil at source with Vaporremed

    A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

  • Decision Support System for the Treatment of Contaminated Soil

     Abstract Recent changes in the Dutch legislation have had a great impact on contaminated soil handling. It is now possible to reuse partially cleaned soil which under the former legislation would have to be dumped. In order to provide civil servants, owners of contaminated soil and the soil cleaning industry with a decision support tool to evaluate the new opportunities for cleaned soil ...


  • Bioremediation replaces “dig and dump” for treatment of pesticides in soil

    Historical usage of organochlorine pesticides (OCPs) such as DDT, toxaphene and dieldrin has resulted in long-term soil contamination, because these substances typically do not degrade naturally at significant rates, so sites are still impacted decades after the end of application. For example, DDT use in Canada ended over 30 years ago, but impacted soil remains at many sites. Such was the case ...


  • Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

    Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Treatment of salt affected soil in the oil field

    Soils, drill cuttings and other solid wastes which are exposed to high levels of salt through spillage from drilling and producing operations, pipe line breaks or leaks, become saturated with sodium. Although the EPA and the industry have demonstrated that the vast majority of such wastes are non-hazardous, in actuality, they have an adverse impact on the fertility of the soil. The degree of salt ...
