One good scoop with a front end loader would pick up and remove many times the volume of contaminated soil. However, the farmer was not allowed to dispose of the contaminated soil by using the simple method of digging it out and hauling it to the approved disposal site. He was required to use an approved hazardous waste disposal firm, and the cleanup was prohibitively expensive. As another example, let's say a bank forecloses on an industrial property. The property owners leave behind several containers of hazardous waste.
Environmental authorities require the bank to dispose of the hazardous waste containers.
To remove the waste, the bank hires a waste removal contractor. The contractor tells the bank it is approved to haul and dispose of the hazardous waste. It dumps the hazardous waste from the bank's property and other firms in someone's field. The field is not a hazardous waste dump. When the property owner learns of the waste that had been illegally dumped on his land, he contacts the environmental authorities.
