Jean Marc de Matteis is a graduate of Ravenscroft School in Raleigh. He lives in Haiti with his wife, Verena. Matteis shared his story and photos of what he has been doing since the earthquake hit last Tuesday.

I have been at GHESKIO (Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections) all day. That is where I will be at most of the time from here on out. Our population has grown to over 2,000 just camped out.

Today, I was able to set up a water purification system that was brought in by an American team. It is solar powered, and they trained me in 10 minutes. You just put the intake into any water source, and it sucks it up thru the filter, and out comes instant potable water. You can even clamp it to a car battery and it will work. It produces 600 gallons a day ... people can just line up and fill up their little containers. While that is short of what we need per day, they have promised me that they are returning on Weds or Thurs! That should make us fairly self-sufficient in terms of water.

Also met with a U.S. Air Force team that was there to assess our needs. They were fantastic, and we are now anxiously awaiting the arrival of soldiers from the 82nd Airborne Division to secure the facility ... Hopefully, they will arrive tomorrow. Their arrival will allow us to begin food distribution safely. In the meantime, we are trying to treat the wounded that we can and transport those we can't to other facilities. We will have a full field hospital set up very soon.
