Systems and processes for decontaminating an aqueous flow contaminated with munitions contaminants

A system for treating a first contaminated aqueous flow comprising water and first munitions contaminants and a second contaminated aqueous flow comprising water and second munitions contaminants to decontaminate interstitial water that percolates through the earth under a destruction area, where munitions are exploded to produce the first munitions contaminants, and a burning area, where munitions are burned to produce the second munitions contaminants, the first contaminated aqueous flow being obtained by allowing a flow of water to fall on the first munitions contaminants, the second contaminated aqueous flow being obtained by allowing the flow of water to fall on second munitions contaminants, the system comprising:

• granulate particles allowing the first contaminated aqueous flow to percolate down therethrough from the destruction area;
• a first adsorption layer buried in the granulate particles and comprising at least one of bone char particulates, titanium dioxide particulates or aluminum oxide particulates for promoting adsorption of the first munitions contaminants upon contact of the first contaminated aqueous flow percolating towards the first adsorption layer and the first adsorption layer to produce a first treated aqueous flow depleted in the first munitions contaminants to further percolate into the granulate particles;
• and
• a second adsorption layer comprising at least one of bone char particulates, titanium dioxide particulates or aluminum oxide particulates for promoting adsorption of the second munitions contaminants upon contact of the second contaminated aqueous flow and the second adsorption layer to produce a second treated aqueous flow depleted in the second munitions contaminants.
