Water Treatment Systems for Total Fluid
& Dissolved Phase Hydrocarbons

Groundwater treatment technologies rely on physical, chemical, and/or biological processes to reduce contaminant concentrations to acceptable levels. When multiple contaminants are present, some technologies may be excluded as complete solutions, but considered as a pretreatment or polishing step in a 'treatment train'.

Air stripping and granular activated carbon (GAC) units may be used to remove organic compounds from groundwater during aquifer tests. Air stripping is generally more cost-effective than GAC for treating volatile organic compounds when flow rates exceed 3 gpm, but may require additional vapor phase treatment.
