Heavy metals in deposit from tunnel drilling is an important issue for environmental management of tunnel construction because heavy metals like arsenic, lead, cadmium, selenium, etc. are very common components in deposit from tunnel drilling. Such deposit is recently stored in soil storage sites with an iron-geotextile composite which is recently used as heavy metal leaching prevention for such deposit storage. An experiment in laboratory by column of sand and an iron-geotextile composite is carried out by solution with arsenic and selenium contaminants.
