WWT sludge hazardous determination: Smart, clear first step

Summary for wwt sludge hazardous determination Discussion

WWT sludge hazardous determination starts with the source, not just the chemistry. In this thread, Gary Kriesch asks how to tell whether sludge from a wastewater treatment facility is hazardous. The reply says, as a former New Jersey governor put it, “Toxic is matter of statute, not opinion,” meaning the first step is to identify where the sludge comes from and whether it is regulated by rule. In the plating industry, for example, the sludge may be listed as F006 WWT sludge, and if so, the proper handling requirements can be found by looking up that code. The answer does not give a universal test method; instead, it emphasizes checking the applicable regulatory listing and then determining what the sludge is and how it must be managed.
