Column Treatability Services
Column studies can be used in instances where the treatment effectiveness cannot be accurately evaluated in a batch test or when higher confidence levels are required to produce scalable results. Column testing provides insight into how groundwater flow rates and residence times may impact the outcomes for remedial technologies applications such as permeable reactive barriers (PRBs). Site geochemical and biological conditions (e.g., air/oxygen supply [or other gasses such as methane]) can also be maintained in columns to simulate site conditions as closely as possible.
In-house testing enables us to monitor the progress of column studies and optimize treatment parameters for full-scale implementation. These studies generate scalable data to inform the design of field applications.
