I was not sure where to post this but I have a question about 55gal plastic drums.
I have been given a bunch of plastic barrels and was told they would have to be rinsed thoroughly (but of course).
these blue barrels had Linear Alkyl Benzene Sulphonic Acid in . Can these be used to store water in for a green house? I'm sure aquaponics is out.
It has the usual cautions for an acid--including taking care when rinsing out if any product still present.
As far as non-food-grade barrels, that appears to be about as safe as you can get. I would have no concerns about using them as water ballast in a greenhouse (paint them black to aid in heat retention).
