“…A comparison of the guidance values (not shown) and the leaching results for metals [50] shows that chromium leaching exceeds the threshold of 0.5 mg/kg dry waste. Furthermore, the mineral oil (C 10 to C 40 ) concentration of the untreated drill cuttings exceeds the 500 mg/kg threshold allowable for landfilling; hence the s/s drilling muds cannot be accepted as inert waste.…”

“…A possible technique for increasing the effectiveness of S/S for organic contaminants is to use another binder with the main binder. In this way, the sorption of organic compound is increased and immobilization is improved, preventing their detrimental effects on binder hydration (Leonard and Stegemann, 2010).…”

Stabilization and solidification a clay soil contaminated with MTBE Abstract:This paper presents an investigation into stabilization and solidification of a clay soil contaminated with MTBE (Methyl Butyl Ether) using two different agents (cement and mixture of bentonite and cement) through a program of laboratory experiments. The samples were prepared in two stages. In the first stage they were prepared with 20 and 30% cement but in the second stage they were prepared with 20 and 30% mixtures of bentonite and cement (with ratios of bentonite to cement equal to 1:1 and 3:1).Unconfined compression tests (UCT) and leaching tests using GC (Gas Chromatography) apparatus were conducted on the samples that were prepared in the above two stages at different curing times. The results show that by using cement, the strength of the soil is increased. The results of the leaching tests on contaminated soil show a major reduction in the concentration of MTBE. Adding cement to contaminated soil causes reduction in concentration of MTBE but by increasing the curing time the concentration of MTBE is increased. It is also indicted that using combination of bentonite and cement leads to reduction in MTBE concentration and the amount of reduction is decreased by increasing the curing time. The bentonite-cement ratio of 3:1 is more effective than 1:1 in reducing the concentration of MTBE.

“…Scanferla et al ( 2009 ) developed and patented an innovative S/S technology using high performance additive (water reducers and superplasticizers) concrete technology and observed superior leaching of heavy metals (99 %) at fi eld-scale. Leonard and Stegemann ( 2010 ) reported more than 90 % immobilization of hydrocarbons in petroleum drill cuttings using Portland cement along with the addition of high carbon power plant fl y ash which act as a novel sorbent for organic pollutants. In stabilization technology, the aim of adding additives is to change the soil physicochemical properties through ion-exchange, adsorption, precipitation, redox potential and pH control.…”

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants. This review is an exploration of the ex-situ technologies for cleaning-up the contaminated soil, groundwater and air emissions, highlighting their principles, advantages, deficiencies and the knowledge gaps. Challenges and strategies for removing different types of contaminants, mainly heavy metals and priority organic pollutants, are also described.
