Florence sparks pollution fears after excrement-filled 'hog lagoons' overflow

Pig waste pits and toxic coal ash pose threat to rivers and homes in North and South Carolina

As residents in the Carolinas continued to deal with the fallout from Hurricane Florence, fears have grown over the storm's longer-term pollution risks - from pig excrement and toxic coal ash potentially seeping into rivers and into people's homes.

Officials said 13 "hog lagoons" - pits filled with pig waste - had overflowed in North Carolina due to the storm, with dozens more likely to follow. In South Carolina, 200,000 tons of coal ash lie in the path of the deluged Waccamaw river, which is expected to reach a record flood stage this week.
