Battelle’s Chlorinated Conference is a landmark event for environmental professionals interested in innovative technologies and approaches to contaminated site management. The event brings together specialists from around the world to share research and experience, offering a valuable opportunity for networking and learning about the latest trends and practices in environmental remediation.
Featured Participation
Danielle Caraça, Technical Production Manager at GEOAMBIENTE® S/A, and Murilo Rocha, Research Coordinator, represented the company with innovative studies:
Danielle Caraça:
Remediation of Chlorinated Solvents and Hydrocarbons through Adsorbent and Oxidative Barriers – Presented in the session “G3: In Situ Chemical Oxidation: Optimized Design Approaches and Lessons Learned.”
Efficient Degradation of Perchloroethylene through Modified Fenton Reaction Using Calcium Peroxide as an Oxidant: A Bench-Scale Study – Presented in the session “F4: High-Resolution Site Characterization (HRSC).”
Murilo Rocha:
Efficient Degradation of Perchloroethylene through Modified Fenton Reaction Using Calcium Peroxide as an Oxidant: A Bench-Scale Study – Presented in the session “G3: In Situ Chemical Oxidation: Optimized Design Approaches and Lessons Learned.”
On the fourth day of the event, GEOAMBIENTE® S/A made history by presenting the innovative study “High-Resolution Site Characterization and Remediation Workflow for Hydrocarbon Remediation.”
Study Highlights
The study focused on risk mitigation in cases of large-scale fuel spills, which generated hydrocarbon contamination in soil and groundwater. Contaminants reached a nearby river, posing risks of explosion and vapor inhalation.
A 3D hydrogeological model was built using historical soil samples and high-resolution data to estimate the total contaminant mass and map retention and migration zones. The contaminant mass was estimated at around 21 tons. With a refined conceptual model, the amount of remediation products needed was reduced from approximately 50 to 20 tons, using a combination of OxyGEO® and SurfGEO® as oxidants.
This study demonstrates that, through innovation and technology, remediation costs for contaminated sites can be significantly reduced. At GeoAmbiente S/A, we don’t just face environmental challenges — we turn them into opportunities for savings and environmental stewardship.
We congratulate our representatives in Colorado, USA, for their outstanding work: Everton Carvalho (Chemical Engineer), Thatiane Kuczera (Chemist), Danielle Caraça (Geologist) and Murilo Rocha (Chemist).
