A new peer-reviewed paper in Frontiers in Microbiology documents the use of Tersus Environmental’s TASK™ MicroEVO™ Self-Emulsifier in laboratory research on chlorinated-solvent contamination in Sydney, Australia. The study explores how site conditions influence the response to enhanced bioremediation.

The Canadian Intellectual Property Office has granted Tersus Environmental Canadian Patent No. 3,109,644, “Enhanced Reduction Bioremediation Method Using In-Situ Alcoholysis.” The patent covers a method intended to advance in situ treatment of contaminated soil and groundwater.

Issued on August 18, 2026, the patent represents Gary Birk’s seventh patent and David Alden’s sixth. Learn more about the innovation and the collaborative effort that supported the patent process.

When significant NAPL remains in the subsurface, treating the dissolved plume alone may mean working against continued contaminant loading.

In this blog post, we look at why source mass reduction should come first—and how surfactant-enhanced aquifer remediation (SEAR) can help mobilize and recover NAPL before transitioning to dissolved-phase treatment.

Take a fresh look at open petroleum UST releases - and the strategies that can help move stalled sites toward closure.

The ASTM E3488-25 Moving Sites to Closure (MStC) framework encourages practitioners to reassess cleanup progress and consider improved remedial strategies. When depleted electron acceptors limit biodegradation, Nutrisulfate® replenishes sulfate to help sustain anaerobic petroleum hydrocarbon biodegradation.

Tersus Environmental is proud to congratulate our technology partner iFLUX on being named a winner of the World Economic Forum’s Water Resilience Challenge, one of the Forum’s most prestigious global innovation recognitions.

Selected as one of only ten winners from more than 340 submissions worldwide, iFLUX was recognized during the World Economic Forum Annual Meeting 2026 in Davos, Switzerland. The award, launched by UpLink and the HCL Group, highlights early-stage innovators whose technologies are driving meaningful progress on some of the world’s most urgent water and sustainability challenges.

If you’ve ever reviewed groundwater performance data for a reductive dechlorination project and noticed acetone, you’re not alone. While not a typical monitoring target, acetone can show up under certain biogeochemical conditions, and its appearance tells us something important about what’s happening underground.
