Oxidation by electrochemistry can treat PFAS-laden waters without creating a secondary waste stream. Traditionally, other water treatment methods only remove PFAS constituents and concentrate them into a waste stream that must then be disposed.

In the field of science which includes soil pollution, natural attenuation applies to nature’s ability to reduce the toxicity, mobility, volume or concentration of contaminants in water and soil.

Abstract from my talk at the American Water Works Association Conference

Rather than attempting to find sources of PFAS (polluters) via large sampling programs of stormwater effluent, some states are requesting, requiring, or ordering local wastewater treatment plants to provide PFAS concentration data.

While the training for hydrology and hydrogeology are completely different, in practice every hydrologist will do some level of hydrogeology and vice versa.
