NEW ORLEANS, April 9 (UPI) -- A water pollution problem in the Gulf of Mexico doesn't come from oil rigs but from farm fields a thousand miles away in the U.S. Midwest, scientists say.
Often overshadowed by events like the 2010 Deepwater Horizon disaster, rainstorms and resulting runoff of agricultural fertilizers are a growing factor in increasingly severe water quality problems in the gulf and the creation of so-called Dead Zones, an expert said.
