Anaerobic Bioremediation Solutions
Terra Systems’ anaerobic bioremediation solutions are designed to deliver faster, more complete treatment of chlorinated solvents under a wide range of site conditions. Our portfolio combines proven technologies that generate reducing conditions, support microbial activity, and drive both biotic and abiotic degradation pathways. Together, these solutions provide a flexible, treatment-train approach to improve performance, reduce uncertainty, and achieve reliable remediation outcomes.
Product Offerings
SRS® Emulsified Vegetable Oil (EVO) Substrates →
Sustained carbon delivery for long-term anaerobic remediation
The anaerobic bioremediation process uses native or introduced microorganisms (such as Dehalococcoides) to break down chlorinated solvents like PCE and TCE into non-toxic end products. Terra Systems’ patented SRS® family is engineered to create reducing conditions and provide a sustained carbon and hydrogen source to support this process. Our in-house manufacturing allows us to tailor formulations to site-specific requirements.
SRS® capabilities include:
+ 45%–90% soybean oil formulations
+ Small or large droplet sizes for optimized distribution or retention
+ Optional nutrients and quick-release substrates to support performance and cost efficiency
QRS™ Quick-Release Lactate Substrates
Fast-acting carbon for immediate anaerobic treatment
The QRS™ family provides injection-ready sodium and potassium lactate substrates that rapidly generate reducing conditions and support microbial degradation of chlorinated solvents. Formulations can include proprietary nutrients and Vitamin B12 to enhance biodegradation performance and improve donor efficiency.
Key products include:
+ QRS™-SL — Sodium lactate, cost-effective and widely used
+ QRS™-SL Plus — Sodium lactate with NutriPlus™ nutrients and Vitamin B12
+ QRS™-PL — Potassium lactate for sodium-restricted sites
+ QRS™-PL Plus — Potassium lactate with enhanced nutrient package
TSI® Bioaugmentation Cultures →
Terra Systems offers a range of TSI® bioaugmentation cultures to support complete biodegradation where native microbial populations are limited or absent.
Capabilities include:
+ TSI-DC® — Dehalococcoides mccartyi culture for complete reductive dechlorination of PCE and TCE to ethene
+ TSI-TCA® — Dehalobacter culture for treatment of trichloroethane (TCA)
+ TSI-DC/TCA Blend — Combined culture for sites with mixed chlorinated solvents
+ TSI-DC RR® — Rhodococcus ruber culture for aerobic biodegradation of 1,4-dioxane
These cultures help prevent stalled degradation pathways and can significantly reduce remediation timeframes.
