Horror Story Using Water-Based Coolant

[TOOLMASTER]

Water and metal is never a good combo.

When I was in high school back in the 60's I worked in a fairly large machine shop, about 100 machinists, and I had the very important jobs like sweeping the floors and cleaning the sludge out of the machines. Some really gross looking and smelling stuff. Back then we just dumped the stuff out back which was pretty much a swamp (I think they are called "meadows" or "wetlands" today.) One interesting consequence was the swamp never froze in the winter, even years after the shop closed. I am quite sure that was just a coincidence!
I know one thing. I won't be using coolant unless I have someone else to clean out the tanks. I was done with that 40+ years ago.

This is one very big reason that smart companies tend to build on virgin land instead of reusing old brownfields. They can or will be stuck with the bill for the sins of the previous users. There should be a way to get a site survey that list all the problems found and start from there. Old is the new baseline, make a new problem you pay, but if you make paper airplanes let say, you should not be responsible for the radioactive waste left by the other guy making weapons grade materials.
