Harriet, The Bore: tunneling under the Miami ship channel ... by gimleteye

The engineers have dubbed the massive drill bit, Harriet, aiming to drill a new tunnel under the Miami ship channel. I wrote giddily on the news story that the contractor was seeking permission to use a polymer to reinforce the walls as the drill passed through the incredibly fragile lime stone.

You might have imagined, that would have been in the original permit application to Miami Dade and to the state. It couldn't be just me.  Drilling horizontally through a few hundred yards of shallow lime rock is like drilling with a 1/8th bit through a foot of pie crust; easy to do, hard to keep the hole open.

Even though I made fun of the issue back in early July, it didn't occur to me the polymer issue would sink in a black hole. Where is Miami Dade DERM? Did DERM give its approval to using toxic polymers to "reinforce" limestone under Biscayne Bay? On what evidence that it won't prove harmful? Does anyone care? At the very least, The Miami Herald should follow up. Why should Eyeonmiami have all the fun?

(Undated photo of a Miami Herald newspaper reporter dictating story to secretary, back when Biscayne Bay was clear as a spring.)

The secretary looks hot. I know, a crude and vile comment! LOL

How weird is it in fact, the Port of Miami tunnel does not yet have its environmental permits from the Florida Department of Environmental Protection to drill under the bay yet it is supposed to start drilling in a few weeks?

A polymer is injected into the porous limestone, cut with a drill aided by lubricants and it's dumped on Virginia Key. It's a mad science experiment on our natural resources. US EPA and independent scientists need to review this entire drilling and dredging plan.
