Israeli law imposes a landfill levy on waste that is buried in landfills. Those that hired the trucks were attempting to avoid paying that levy.
The environmental impact of illegally dumping waste are severe, and include water contamination, soil contamination, and waste fires that constitute a nuisance to nearby residents.
The David Unit was established by the Ministry of Environmental Protection (MoEP) in December 2013 in order to cope with the phenomena of smuggling waste into the West Bank and illegally dumping it there, as well as smuggling of logs to be used to make charcoal.
Dozens of vehicles are checked each day in order to prevent these illegal activities. Since the unit began operating, some 300 vehicles were caught and confiscated.
