| Batch and column tests were conducted with common groundwater contaminants (i.e., trichloroethylene) to determine transport parameters and reactivity of the foundry sands. The reactivities of foundry sands for common groundwater contaminants are comparable to or slightly higher than those for Peerless iron a common medium used in permeable reactive barriers. In addition, the TOC and clay in foundry sands can significantly retard the movement of target contaminants, which may result in lower effluent concentrations of contaminants due to biodegradation. In general, permeable reactive barriers with the thickness of 1m can be constructed with many foundry sands to treat typical groundwater comtaminants provided the zero-valent iron content in the foundry sand is higher than 1%. |
