Integral biopile components for successful bioremediation in the Arctic

On-site and in situ remediation technologies applicable to petroleum hydrocarbon contaminated sites in the Antarctic and Arctic

“…Air humidification systems can reduce volatilization by promoting biodegradation due to high soil moisture content (which reduces the soil-pore space available for diffusion) and increased bioavailability of adsorbed organic compounds that have been displaced from soil particles by water (Batterman et al 1995;Sanscartier et al 2009). Heating cables and blankets may be used as an alternative to air pumps but tend to be less efficient (Filler et al 2001). Volatilization associated with low water availability can also discourage microbial activity, so heating systems should be used with caution (Sanscartier et al 2009;Bolton 2012).…”

Theoretical Application of Decision Support System in Petroleum Contaminated Ogoniland in South-Southern Nigeria

“…The result of soil logs from Nsioken Agbi Ogale, Eleme is shown in Figure 2; Considering that the oil spills took place between 1986 and 1990, natural attenuation, or biodegradation of contaminants has not proven effective in reducing contaminant concentrations to safe levels in the affected area [5,[24][25][26][27][28][29][30][31][32][33]. Another reason why natural attenuation has failed is the presence of silty clay or pure clay soil in some areas.…”

Ex-Situ Remediation Technologies for Environmental Pollutants: A Critical Perspective

“…Reimer et al ( 2003 ) reported 60 % TPH degradation when the temperature of petroleum hydrocarbon-contaminated soils in the Arctic was maintained at 15 °C by injecting heated air into the biopile. Filler et al ( 2001 ), on the other hand, used heating cables and blankets for enhancing the contaminant volatilization effi ciency in a biopile system. A pilot study was conducted by Genovese et al ( 2008 ) to evaluate the effect of bioaugmentation in a biopile.…”
