The paper reports a pilot injection test of microsized zerovalent iron (mZVI) dispersed in a
guar gum shear thinning solution. The test was performed in the framework of the EU
research project AQUAREHAB in a site in Belgium contaminated by chlorinated aliphatic
hydrocarbons (CAHs). The field application was aimed to overcome those critical aspects
which hinder mZVI field injection, mainly due to the colloidal instability of ZVI-based
suspensions. The iron slurry properties (iron particles size and concentration, polymeric …
