  • Temperature effects on bioremediation of PAHs and PCP contaminated South Louisiana soils: a laboratory mesocosm study

    Goal, Scope and Background. Temperature and soil moisture content are important environmental variables in bioremediation technologies.Optimizing these variables in-situ would enhance andmaintain remediation of hazardous wastes during cold winter seasons or in cold regions and may lead to reduced maintenance and/or cost. The effect of elevated temperature and soil moisture on bioremediation ...


  • Surfactant desorption is key to successful PAH bioremediation

    Formulations which are patented non-ionic surfactant mixtures used in the in situ and ex situ treatment of petroleum hydrocarbons, chlorinated solvents, heavy metals, and more recently PAHs, PCBs and MTBE type contaminated waste are involved in Surfactant Enhanced Bioremediation (SEB®) using Iveysol ®. These surfactant formulations have the ability to enhance soil biodegradation. During in ...

  • Effect of humic compounds on bacterial growth in bioremediation of pahs

    Polycyclic Aromatic Hydrocarbons (PAHs) are introduced into the environment through natural and anthropogenic combustion processes causing them to be ubiquitous in environment (Menzi et al., 1992; Juhasz and Naidu, 2000 and Nieman et al., 2001). These compounds are potentially carcinogenic, mutagenic and toxic contaminants (Yerushalmi and Guiot, 2001; Verrhiest et al., 2002; Samanta et al., 2002 ...

  • Guidelines for the use of mosses and soils in monitoring contaminant fallout

    In 1999 Italy’s Environmental Protection Agency (ANPA) published a paper on the methods to be used in the case of mosses and soils. After nearly a decade, a review is advisable. The attached Guidelines take account of numerous experiments in the environmental field and include a short description of bryophyte biology. A great many pollutants are present in our environment. In addition to ...

  • Polycyclic aromatic hydrocarbons in Niger Delta soil: contamination sources and profiles

    Abstract The distribution and sources of PAHs in soil as well as PAHs profiles have been investigated in areas with anthropogenic pollution in the Niger Delta (Nigeria) such as Warri and Ughelli. PAHs were identified in 21 soil samples (0- 10cm upper layer) collected in May, 2003. The typical total PAHs level in Niger Delta soil ranged from 182 ± 112 – to - 433 ±256 ìg/kg dw. PAH ...

  • Phytoremediation of Alkylated Polycyclic Aromatic Hydrocarbons in a Crude Oil-Contaminated Soil

    Abstract  Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four ...


  • Soil Remediation

    Contaminated sites by hazardous substances are a major environmental concern in Europe e throughout the world. Significant financial and human resources are devoted for the remediation of such sites. Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • Emission of N2o from Polycyclic Aromatic Hydrocarbons contaminated soil at different water contents added with vermicompost

    Vermicompost is typically applied to improve soil quality, but can be used to remediate hydrocarbon-contaminated soils. Little information is available on how contamination and subsequent bioremediation with vermicompost affects emissions of N2O and CO2, important greenhouse gases. A sandy loam soil with different water contents (40%, 60%, 80% and 100% of water holding capacity (WHC)) was ...

  • In-situ remediation of Polycyclic aromatic hydrocarbon contaminated soils - New Jersey, USA case study

    Executive Summary A New Jersey utility company operated a regulator station on the site of a former manufactured gas plant in central New Jersey. The gas transfer station contained a large natural gas feeder main that fed major population centers in the southern part of the state. The regulator station contained an area approximately 3,600 ft2 contaminated to a depth of 1 meter with both ...

  • Pollution retention capabilities of roadside soils

    ABSTRACTRunoff from highways contains significant loads of heavy metals and hydrocarbons. According to German regulations, it should be infiltrated over embankments to support groundwater-recharge. To investigate the decontaminating effect of greened embankments, soil-monoliths from highways with high traffic densities were taken. Soils were analyzed to characterize the contamination in relation ...

  • Managing bioremediation of a creosote-contaminated superfund site by optimizing moisture and temperature in a biopile

    Soil moisture content and temperature in a contaminated soil biopile equipped with immobilized microbe bioreactors (IMBRs) were optimized during ex situ bioremediation at a creosotecontaminated Superfund site. Efficiency of remediation during warm summer months without soil-temperature and moisture optimization was compared with that of cold winter months when corrective measures were applied. ...


  • Environmental and health risk assessment of an oil contaminated site in the Mexican tropical southeast

    The aim of the present study was the environmental and health risk assessment of the oil contaminated soil in the Mexican tropic. The case is based on the total petroleum hydrocarbons (TPH) and polycyclic aromatic (PAH) soil contamination resulting from the activities of the oil industry over 70 years. The results of this study were estimated using CalTOX, a multimedia exposure model. The ...

  • The use of biostimulation and bioaugmentation to remove phenanthrene from soil

    Biostimulation and bioaugmentation are commonly employed as technologies to remediate numerous environmental problems. In the last few decades, both technologies have been used to treat polyaromatic hydrocarbons (PAHs). This paper presents a brief survey of some bioremediation aspects, with particular reference to phenanthrene removal from soil, since this compound is the main model substrate for ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Soil Reclamation Through Chemical Oxidation

    Supplying ozone (chemical) oxidation equipment to clean soil and groundwater is Kerfoot Technologies' specialty. In the past, contaminated soil was dug and removed to a disposal location. Present-day engineering relies increasingly on smart in-situ technologies with minimal site disturbance. Chemical oxidation is at the forefront of those technologies. ...
