This is the UNICEF website for Hurricane Maria -- the link is at the bottom.  90 percent of donations go to support victims, which is not 100 percent but still okay --  Andrew

"Puerto Rico is in a state of crisis. In the wake of Hurricane Maria, mass flooding and destruction have put children throughout the island at risk.

The governor has warned that this is “the worst hurricane in a century,” and that rebuilding will be a tremendously difficult undertaking.

UNICEF USA is mobilizing to get immediate, critical support — Emergency Relief Kits — to the children of Puerto Rico.

A donation of just $28 will provide a kit containing basic, essential supplies such as water purification tablets, a water bucket with lid, water containers, soap, toothpaste, detergent and sanitary pads. The supplies will help children and their families keep clean and healthy, protecting them from diseases that can occur after the loss of equipment and infrastructure and the disruption of a safe water supply. 

UNICEF is a global leader in emergency response, last year reaching children in 344 humanitarian emergencies across 108 countries. We stand ready to provide aid before, during and after a crisis.

90% of every dollar spent goes directly to helping children."
