🌟 Sherri Scott relocates to Aiken, SC 🌟

We are excited to announce that Sherri has recently relocated to Aiken, South Carolina, where she looks forward to continuing to serve our clients in the Southeast. Sherri brings with her the same dedication and excellence you've come to know over the past decade.

Aiken is a hub for horseback riding, and when she’s not helping our clients, you can probably find her spending time in the saddle.

Welcome to South Carolina, Sherri! 🐎

Tersus Environmental (www.tersusenv.com) is pleased to announce that the U.S. Patent and Trademark Office has issued patent 11,491,522 (the ‘522 patent) which further strengthens the company’s intellectual property coverage for the diverse selection of products and technologies addressing the remediation of contaminated soils and aquifers.

Officially granted on November 8, 2022, the ‘522 patent is titled, “Zero-Valent Metal Suspension in Non-Aqueous Phase for Water Remediation.” This is the company’s second patent related to zero-valent metal particle suspensions. U.S. Patent 11,123,779 B2 titled “Method and a Chemical Composition for Accelerated In Situ Biochemical Remediation” was granted on September 21, 2021.

The ‘522 patent claims are generally directed towards a zero-valent metal particle suspension for the remediation of soil and groundwater. The claims are also generally directed towards a chemical composition comprising vegetable oil, an oil thickening agent, a surfactant, and a particulate zero-valent metal forming a zero-valent metal suspension in a non-aqueous phase, wherein said suspension network comprises zero-valent metal particles encapsulated within a liquid membrane formed of the vegetable oil.

Authors for the newly issued ‘522 patent include Sangho Bang, Ph.D.; David Alden P.E.; Gary Birk, P.E.; Jeff Harwell, Ph.D.; and Benjamin Shiau, Ph.D.

We research, develop, and commercialize innovative soil and groundwater remediation solutions in order to meet the increasing technological demands at contaminated sites. Our proven technologies help our clients reduce uncertainty, minimize risks, and achieve cost-effective results.

Gary Birk discussed how Compound-Specific Isotope Analysis and Molecular Diagnostic Tools help distinguish sources, allowing practitioners to address only contaminant they are liable for. Joining him on the panel were Tim Agajanian, Brad Temple, and Andrew Lojo.What an honor to be hosted by the New York Athletic Club!

Tersus Environmental adds to its patent portfolio with issuance of US Patent 11,123,779 B2, Method and a Chemical Composition for Accelerated In Situ Biochemical Remediation.

Officially granted on September 21, 2021, the claims are generally directed towards a method for supplying a mixture comprising ferrous sulfide and zero-valent metal particle reactants into soil pathways to biologically react with dissolved contaminants in groundwater. Further, an organic hydrogen donor is supplied into the soil-pathways to produce anaerobic-conditions to cause indigenous anaerobic bacteria to biodegrade residual concentrations of the contaminants. The claims are also generally directed towards a chemical composition comprising vegetable oil, an oil thickening agent, and a surfactant forming suspension networks for ferrous sulfide and zero-valent metal particle reactants, wherein said suspension network comprises ferrous sulfide and zero-valent metal particles encapsulated within a liquid membrane formed of the vegetable oil.

Compound-specific isotope analysis - or CSIA is an analytical method that measures the ratios of naturally occurring stable isotopes (e.g., 13C/12C, 2H/1H, or 37Cl/35Cl) in environmental samples. This characterization tool can be used for demonstrating in-situ destruction of selected VOC and for forensic investigations to gain information about potential contaminant sources, the extent of degradation, commingling of contaminant plumes, and the origins of some chemicals.

Our goal is to provide you the CSIA expertise you need to effectively implement this technology on your site. Whether the assessment concern forensics, natural attenuation or remediation treatment performance, our Team can offer valuable support. To learn more visit www.tersusenv.com.
