A case study on application of solidification/stabilization technique for remediation of contaminated marine sediments in the Republic of Korea

Abstract

Sediments in coastal areas where are adjacent to industrial complexes, ports and commercial facilities could be easily contaminated with harmful chemicals such as heavy metals. Solidification/stabilization is one of the ex-situ remediation methods which have been widely applied. To evaluate the effect of solidification/stabilization method to apply ex-situ remediation, heavy metal leaching test was conducted from raw and solidified/stabilized sediments sampled at Masan bay (Korea) where polluted with heavy metals such as zinc and copper (over clean-up index for harmful chemicals, CIHC, Korea). The sediments were treated under various conditions and cured. Then, leached heavy metals were analyzed following a standard toxicity characteristic leaching procedure (TCLP,USEPA).methods which have been widely applied.
