The problem: They do not simply bind to conventional soil but are highly mobile and migrate directly into groundwater when it rains. In practice, this makes contaminated soil a \"wandering hazardous waste\".<\/p>\n\n        <p>Stehr, holder of over 100 patents, has taken on this enormous challenge and developed a pioneering system to solve the problem: mixing in activated carbon to immobilize contaminated soils.<\/p>\n        \n        <p>The <strong>PEFAS system<\/strong> is currently the absolute trending topic in the industry \u2013 and for good reason.
