REGENESIS invites you to a limited educational webinar series presented by Dr. Jeremy Birnstingl, a leading environmental expert, on the application of advanced modelling for in situ groundwater treatment using colloidal activated carbon.
This ground-breaking three-part series provides insights and examples into the power and utility of modelling to assist throughout a project, from conceptional and formal design stages to performance data interpretation, management and optimization.
The series has been developed specifically for environmental professionals focused on optimizing and better understanding best practices when developing designs to maximize the effectiveness and longevity of a remedial solution that incorporates colloidal activated carbon technology.

About PlumeStop and PlumeForce Modelling Software
PlumeStop colloidal activated carbon, a patented micron-scale amendment, has been used in the treatment of groundwater contaminant plumes for almost a decade. PlumeStop is comprised of micron-scale particles of activated carbon in liquid suspension injected into groundwater contaminant plumes. The carbon particles attach to the soil matrix and adsorb the contaminants from solution, quickly and effectively reducing contaminant concentrations, migration, and risk.
The use of PlumeStop is often regarded as a means of capturing and immobilizing contaminants. This can be a helpful initial perspective, but it is more accurate to consider the remedial approach as a means of engineering the partitioning equilibrium (Kd) of the contaminants between the soil and the groundwater. Advanced modelling enables the wider dynamics of the process to be better understood. It also opens up the potential use of modelling as a tool to support the design and management of colloidal activated carbon projects, since Kd is a fundamental parameter of all groundwater fate and transport models.
The PlumeForce software is a modelling tool developed and used internally by REGENESIS for project design and interpretive support. At its core, it is a finite difference model that combines multi-phase biotic and abiotic degradation and transformation rates of target and non-target species with their retardation and transport within an aquifer. Competitive interactions are dynamically and quantitatively accommodated. This is particularly helpful in relation to competitive sorption / competitive displacement on activated carbon.
