An oil spill covered the Mississippi River near New Orleans when an accident occurred on Wednesday.
Look on nola.com for up to date information. People are stocking up on bottled water because there's a chance that tap water may not be safe to drink yet.
My contact in New Orleans has informed me that a group of volunteers at the Healthy Soil Project (email@example.com) has been working to help with the cleanup on their turf (no pun intended). This is a group that has been working on getting toxins out of the soil near the levees over the last year. If you want to help, they are accepting donations of respirators, tyvek suits, joy brand dish soap, and hair mats (if you want to mail any of these items, please contact the email address above), as well as donations of money.
