Coal tar in sediment has proven to be a more recalcitrant contaminant issue than at first realized. American ingenuity has only now devised an elegant remediation solution that is both certain and permanent. To address all the shortcomings of traditional methods, scientists and engineers at our company engineered an approach that caps and controls contaminant release by managing the migration of gas bubbles. NAPL trapping cap designs are suited to a range of settings.
