ABSTRACT: For groundwater and soil remediation in a habitat of refining plant Slovnaft in vicinity of Vojany was suggested and realized a remediation technology. This technology combine some technological methods with relative conditioned effects. Realized technology take advantage of bioventing, biosparging, pumping of groundwater with biodegradation and stripping. For elimination of oil compounds in air was realized biofilter. Operation results demonstrated that preventing - remediation system realized in 1997 is possible to state, that developed groundwater and soil remediation technology in refinery Slovnaft Vojany is satisfactory and effective.
