To clarify, this is NOT related to fracking. It is related to shallow, horizontal drilling to install the Mariner Pipeline.
The “drilling fluid” mentioned in article is likely a bentonite slurry, which is a mixture of the natural clay mineral “bentonite” and water. Bentonite usually comes from clay mines in WY. While true, it can “smother” benthic life, like mayfly larvae, it is more akin to sediment than a toxic chemical.
Just wanted to clear the air. It does not make the spill right, just wanted to take some of the drinking water contamination by fracking drama out of the post.
The sinkholes and pipeline integrity, however, are a serious point of concern.
