Single chelating washing and chelate-DOM washing were carried out using ethylenediaminetetraacetic acid (EDTA), citric acid, and DOM solutions to remediate highly Cu-contaminated soil. Two-phase washing using 0.34 M citric acid and then 1500 mg L (-1) DOM solution (pH 8.5) was found to be most favorable for the soil.

To make these walls strong, you need to add "dead men," anchors that lock the wall into the soil behind them. The same pressure that's pushing against the wall pushes down on the dead men to keep them (and therefore the wall) in place. The principles of stepping back, installing good drainage and compacting also apply to timber walls.
