Last night I was driving home, and noticed that Laurel Fork (along Hwy 105, just outside of Boone) was running a grayish color. I tracked down the source of the gray water, and it turned out to be the discharge from the Vulcan Boone Quarry (Just south of Boone on 105). Here is a video and some pictures of what I found.
The Vulcan Boone Quarry has had repeated problems in the past with discharging milky white and gray water and they got in trouble for it before. As a result they have some fancy monitoring equipment to watch their discharge. The question remains, why is this still going on if they have they monitor this water, and if they have gotten in trouble for this before?
Check back for updates on what Vulcan and the North Carolina Division of Water Quality are going to do about this.
