In the aftermath of Hurricane Florence, I’ve joined millions who’ve watched with horror as the Carolinas have been inundated with floodwaters and worried about the various hazards those waters can contain. We’ve seen heavy metal-laden coal ash spills, a nuclear plantgo on alert (thankfully without incident), and sewage treatment plants get swamped. But the biggest and most widely reported hazard associated with Florence appears to be the hog waste that is spilling from many of the state’s thousands of CAFOs (confined animal feeding operations), and which threatens lasting havoc on public health and the local economy.
And while the state’s pork industry was already under fire for its day-to-day impacts on the health and quality of life of nearby residents, Florence has laid bare the lie that millions of animals and their copious waste can be safely concentrated in flood-prone coastal areas like southeastern North Carolina.
The state is home to 9.7 million pigs that produce 10 billion gallons of manure annually. As rivers crested on Wednesday, state officials believed that at least 110 hog manure lagoons—open, earthen pools where pig waste is liquified and broken down by anaerobic bacteria (causing their bubblegum-pink color) before being sprayed on fields—had been breached or inundated by flood waters across the state:
The tally by the North Carolina Department of Environmental Quality is rising rapidly (it was just 34 on Monday). Perhaps not surprisingly, the state’s pork industry lobby group is reporting much smaller numbers: by Wednesday afternoon, the North Carolina Pork Council’s website listed only 43 lagoons affected by the storm and flood.
In any case, the true extent of the spills may not be known for many days, as extensive road closuresin the state continue to make travel and assessment difficult or impossible.
In 2016, the Waterkeeper Alliance and the Environmental Working Group used federal and state geographical data and analyzed high-resolution aerial photography to create a series of interactive maps showing the locations and scale of CAFOs concentration in the state. The map below shows the location of hog CAFOs (pink dots), poultry CAFOs (yellow dots), and cattle feedlots (purple dots) throughout the state.
