I found a free tote that had this waste water treatment stuff in it. According to several sources its low PH, easy to clean out of the tote, possibly gets washed into rivers/streams, and has a base of aluminum or iron in the coagulant. I seem to find the worst of the worst when it comes to totes. Anybody heard of this or have used a tote that had waste water coagulant in it? I am waiting on a MSDS sheet on it and from what I have read it is not considered hazardous.
