Before the Iraqi district of Sinjar in Ninewa province fell into the hands of the Islamic State, foul drinking water was making people sick with preventable diseases. The U.S. tried to fix the problem by digging wells and treatment facilities, but poor oversight and shoddy work from contractors left the area no better than it had started, despite millions of dollars spent in reconstruction money. An investigation into Iraqi efforts to fix the problem after the U.S. withdrew showed that projects remained unfinished, but money for maintenance and fuel continued to pour into the pockets of local officials. In an area where extremists use frustration over corruption to recruit followers. the implications of this corruption couldn't be more serious.
