ABSTRACT
An experimental study was conducted on the manifestation of organic contaminant-reactive geosynthetic liner for preventing the spread of contaminated groundwater. The polymer which has absorb oil highly and self-swelled was selected for the organic pollutant reactive geosynthetic barrier. This polymeric material has composited with nonwoven and film woven by needle punching process as GCLs. The geosynthetic oil absent liner prepared was immersed in organic pollutant material (TPH and TCE) for 24 hours and the permeability coefficient was evaluated (ASTM D5887). The permeability coefficient of the geosynthetic oil absent liner immersed in TPH and TCE was resulted in 7.3 × 10−8 cm/s and 1.1 × 10−8 cm/s, where the value of α × 10−2 cm/s for the normal water as a control test. It was confirmed that the geosynthetic oil absent liner showed an orderly behavior that could sufficiently perform the role of a liquid barrier to prevents the spread of contaminated groundwater.
