This is very interesting. In courses for my Environmental Restoration and Hazardous Waste Technology degree, one of the primary tenets they repeatedly drilled into us was that “Dilution is NOT a solution to pollution.” For instance, when remediating contaminated groundwater, it is NOT okay to simply dilute the contaminated water with more water. Proper remedial action requires that the hazardous contaminants be stripped out–e.g., evaporated, chemically chelated, filtered or otherwise diminished–to attain an acceptable level of safety. This very basic tenet of what is taught in college-level environmental remediation classes is exactly the OPPOSITE of what HBI says.
