the toxins in the anbar mitch lowe remain for decades to come. water is pumped -- the toxins in the environment will remain for decades to come. keenest take samples to test. the liquid contains chemicals that can cause cancer, a substance at the plant can remove the toxins by binding with them chemically, leaving the water clean. the toxic residues can be converted into harmless substances. >> there is an odor, otherwise, it has the typical small. the final products are water, carbon dioxide, and hydrochloric acid. >> it means they can be reused, like almost all the residues from the plant. the process results in a small amount of sulfur is residue that must be removed as it can damage the equipment. scientists have come up with a new process to achieve that, it is in the testing stage right now. researchers hope will be ready to be used in the treatment plant in a few months' time. the goal is to develop a substance that can decontaminate the ground directly. this black substance is able to absorb contentment and -- contaminants and break them
