The TV series “This American Land” has a new segment o
n the factory hog farm in the Buffalo River watershed and the concerns neighbors have about potential pollution of the national river.

The segment runs just under 8 minutes. It includes some aerial photos of the hog waste holding pond at the farm, something I hadn’t seen previously. There’s also graphic illustrations of the underground limestone and the crevices that many fear can be a path to taking waste into the water.

The owners of the hog farm declined to participate in the segment, but some local people spoke in favor of it. Generally, I think opponents of the hog farm will like it. It’s part of a series on conservation that appears on PBS.
