This study was conducted to investigate water movement in hydrocarbon contaminated soils. Three soils were studied, a hydrocarbon contaminated soil, the same soil after 3 years of bioremediation, and a control soil from the same site. There was a critical soil water content around 18% (bioremediated soil) and 20% (contaminated soil), above which the sorptivity of the contaminated soil was near that...
Much effort has been focused on defining the end-point of bioremediated soils by chemical analysis toxicity tests. However, these tests do not assess the quality, or the capability, of soil to support plant growth after bioremediation. We studied the response of plants to hydrocarbon contaminants by camparing barley (Hordeum vulgare) growth on: (i) control soil, agricultural topsoil, (ii) oil-contaminated...
