Copper Sulfate

[sailormatlac]

I suspect Crystal Copper Sulfate was hauled in covered hoppers and Copper Sulfate (chemical) is haul in tank cars or tanker trucks.

Ans yes the crystals is use to remove algae from ponds,swiming pools and has many other uses.

Brakie, Yes, we are talking about the fungicide.

The funny thing is that it was piled up in the open air according to the maps and old pictures... wasn't there a risk it would have reacted with the elements? I'm just puzzled because Copper Sulfate is blue, it would have made quite a sight in a harbor.
