"Bioremediation of Contaminated Soil Using Vermicompost Tea and Biopolymer"

Bioremediation approaches have gained renewed interest as environmental problems continue to rise.  In the past decade, vermicomposting has become more important because it is intrinsically environmentally friendly.  This study investigated the effectiveness of vermicompost tea and a biopolymer as flushing agents for the remediation of sand contaminated with waste engine lubricant oil.  The contaminating agent was injected into a sand pack using a pump.  Five displacement experiments were conducted.  Vermicompost tea/biopolymer and/or tap water/bio polymer was injected into the contaminated sand pack following a pre-established injection sequence.  The results showed that remediation using vermicompost tea removed 98% of the pollutant, while the baseline experiment removed a maximum of 82% of the hydrocarbon contaminant.  Germination tests revealed no phytotoxic effects of sand remediated using vermicompost tea flushing agents.  Overall, this study demonstrated the effectiveness of vermicompost tea/biopolymer as bio-flushing agents for the remediation of sand contaminated with hydrocarbon derived pollutants.
