Remedial Process Optimization: Increased the sustainability of international remediation while reducing the cost

Remedial Process Optimization: Increased the sustainability of international remediation while reducing the cost.

With data comes knowledge; we strive to support that statement every day.  We endeavor to show that collecting data is not just a process but a means of effecting change.  Remedial processes can often be optimized using a careful analysis of the data and open communication with the stakeholders.  

At an industrial complex, an extensive groundwater hydraulic barrier and treatment system was installed in 2002 to protect the groundwater receptor, a river.  Data was being collected but was it the right data, and how was that data being interpreted?  We were retained to conduct a detailed evaluation of the site to determine if the remedy was appropriate and if the approach could be improved. 

Through a detailed site characterization, which included continuous hydraulic data collection through automated telemetry systems and data visualization, we were able to provide a sustainable remedial process.  The original hydraulic barrier system was shown to be inefficient, based on the identification of a subsurface paleo-current impacting the efficiency of achieving hydraulic control through pumping.  We recommended a strategy change utilizing natural and passive systems to redirect groundwater flow, reforestation, and phytoremediation to protect the surrounding environment.  Upon review, stakeholders agreed that the proposed remedy change was the appropriate choice for the long-term management of the site, which will result in a multi-million dollar savings to the client.
