Many sites develop underground plumes of VOCs, PCBs, and heavy metals.
Contaminated plume migration through the vadose zone ultimately pollutes groundwater resources, and in some locations, has already damaged off-site environments. The most effective, and efficient, control of groundwater contamination is at the source. For general applications, a new less costly adsorbent is needed to realize the full potential of permeable barrier technology. Derived from negative cost municipal biosolids, LCAC is capable of adsorbing a broad range of organic pollutants. Depending on application requirements, LCAC is producible in either powdered, granular, or pelletized forms.
