What Are the Best Bioremediation Products for Contaminated Groundwater?
Selecting Groundwater Bioremediation Products for Contaminants and Site Conditions What are the best bioremediation products for contaminated groundwater? The best bioremediation products are those that match the contaminants, groundwater chemistry, geology,…
TCE Plume Bioremediation at Dover Air Force Base
Newman Zone EVO Supported Treatment of a 6,000-Foot TCE Plume Without Disrupting Military Operations Dover Air Force Base in Delaware faced a large TCE plume created by historical releases of degreasing solvents used during aircraft maintenance. Accelerated anaerobic…
Brownfield Bioremediation Reduces Chlorinated Solvents by 98%
Newman Zone EVO and Neutral Zone Support Rapid Treatment at a California Mixed-Use Redevelopment Site A former industrial property in Emeryville, California, was being prepared for commercial, retail, and residential redevelopment. Although soil excavation removed…
TCE Bioremediation Project, Orange County, CA
The Legacy Remediation Team completed a four-week bioremediation project for Murex Environmental at a multi-tenant industrial property in Orange County, California. The primary groundwater contaminants of concern (COCs) were PCE, TCE and cis-1,2-DCE. The selected…
Successful Treatment of High-Concentration TCE at a Texas Manufacturing Site
This TCE groundwater remediation case study examines high-concentration TCE treatment at an auto parts manufacturing site in Stephenville, Texas. Newman Zone emulsified vegetable oil rapidly reduced TCE, while buffering and Dehalococcoides bioaugmentation supported complete dechlorination to ethene.
Bioremediation vs. Bioaugmentation
Biostimulation vs. Bioaugmentation: Understanding the Difference—and When You May Need Both Biostimulation and bioaugmentation are two of the most effective tools available for in situ groundwater remediation. They are also two of the most misunderstood. Although the…
How to Evaluate Bioremediation Product Suppliers
An Engineer’s Guide to Evaluating Bioremediation Product Suppliers Selecting a bioremediation product supplier involves more than comparing product prices or reviewing a specification sheet. The success of a remediation project depends on choosing products that match…
The Two Biggest Challenges in Bioremediation (and How to Solve Them)
Bioremediation is often described in terms of chemistry and microbiology—but in practice, most projects succeed or fail based on two very practical engineering challenges.
