Selective spoil site management has proven to be one of the most successful measures to protect surface and groundwater supplies from contamination, and may be a valid practice to apply in the future construction of dump sites. The improvement of drainage system quality through this procedure can also significantly reduce the cost of purification treatment prior to discharge into the receiving catchment zones. The residue released during the waste removal process could be further processed and recycled, or it could be sent to safe disposal sites that would not risk human health in the communities surrounding the site.
