"Many reconstruction efforts on the ground are underway, but security concerns have slowed progress considerably. Of the nearly $29 billion in appropriated funds from all accounts directed at reconstruction purposes, close to 40% is targeted at infrastructure projects- roads, sanitation, electric power, oil production, etc. About 38% is used to train and equip Iraqi security forces. A range of programs- accounting for roughly 22% of appropriations- are in place to offer expert advice to the Iraqi government, establish business centers, rehabilitate schools and health clinics, provide school books and vaccinations, etc. Of the nearly $21 billion appropriated to the Iraq Relief and Reconstruction Fund in the FY2003 and 2004 supplementals, $19.0 billion had been obligated and $14.3 billion spent by early May 2006."
