Chickens, manure, and arsenic

Article Abstract:

Chicken farms located on the Delaware-Maryland-Virginia peninsula are releasing 20-50 metric tons of arsenic into the environment on a yearly basis. There is fear that this arsenic carries the potential to become mobilized and infect surface and groundwater. Researchers with the United States Geological Survey are studying arsenic concentrations where poultry waste has been applied to determine how the arsenic is distributed, how it got there, the method of transportation and what follows after it's application.
