AN INTEGRATED APPROACH SUPPORTING REMEDIATION OF AN AQUIFER CONTAMINATED WITH CHLORINATED SOLVENTS BY A COMBINATION OF ADSORPTION AND BIODEGRADATION
Ciampi, P., C. Esposito, P. Viotti, J. Boaga, G. Cassiani, and M.P. Papini.
Applied Sciences 9:4318(2019)
In Bologna, Italy, ~1,000,000 m3of chlorinated solvent-contaminated soil was excavated to create a new high-speed railway station. Simultaneously, a bypass system equipped with activated carbon was installed to treat groundwater contaminated with TCE and PCE. Heterogeneous data, including geological/hydrological, geophysical, and chemical data, were stored and centralized in an information management and analysis platform. The data were used as a "cockpit" to assist in the design, remedy selection/implementation, and monitoring of a groundwater remediation pilot test. The selected remediation strategy involved creating reactive zones using the combined actions of PlumeStop™ and HRC™ to adsorb contamination and stimulate dechlorination. Results of post-treatment monitoring revealed abatement of the chlorinated solvents and intense biological dechlorination activity. Achieving the remediation objectives and project closure is based on the integration of multidisciplinary data using a multiscale approach. https://www.mdpi.com/2076-3417/9/20/4318/pdf
