BTEX remediation in groundwater
BTEX contamination in groundwater from a leaking underground storage tank was cost-effectively treated with two applications of Petrox. This project demonstrates the rapid degradation of petroleum components when high populations of Petrox aerobic microbes are injected. The pre-treatment concentrations of Toluene and Xylene were 1,198ppb and 2,408 ppb, respectively. Ten units of Petrox aerobic ...

Case study – BTEX contamination - Kentucky
In 1992, remedial activities began at the Shively Service Center located in Radcliff, Kentucky. After the leaking underground storage tanks were removed from the site approximately 1,500 cubic yards of BTEX impacted soil was excavated and disposed off-site from the tank pits. Based on the review of historical sampling activities it was believed that the majority of the impacted soils were removed ...

The power of precise remediation
Design matters in in-situ remediation. Just ask Resource Geoscience, Inc. (RGI), a Remediation Products, Inc. BOS 200 approved installer and certified Trap and Treat Consultant. They recently demonstrated that when paired with proper injection design and precise application, BOS 200 can get the job done where others fail. The site: Contaminated clay site in Colorado The contamination: BTEX ...

Statistical analysis of main and interaction effects during the removal of BTEX mixtures in batch conditions, using wastewater treatment plant sludge microbes
Biodegradation has proved to be a versatile technique to remediate benzene, toluene, ethyl benzene and xylene (BTEX) mixtures in contaminated soil and groundwater. In this study, a mixed microbial culture obtained from a wastewater treatment plant was used to degrade liquid phase BTEX, at initial concentrations varying between 15 to 75 mg/l. Experiments were conducted according to the 2k-1 ...

Spolchemie site remediation and NanoRem field site application
Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the current ...

HD#7 - Groundwater BioLogix Application - Case Study
Case Summary After three underground storage tanks were removed from the location of a convenience store, investigation showed that petroleum contamination was present in a small area near the former dispenser island. The vadose-zone contaminated soil was excavated and disposed off-site. Ground water monitoring showed that the ground water impact was limited to a small area near the source of ...

HDPE - A Hydrocarbon Resistant Membrane?
Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane. However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation. It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment or building ...

Analysis and monitoring of wastewater quality for refinery processes - Case Study
Context & Challenges Following the publication of a ministerial decree on August 24, 2017, French industrial activities must meet compliance requirements on the quality of discharges of hazardous substances into water from environmental protection installation. Industrials are particularly targeted by these new guidelines and must adapt their monitoring systems. Chromatotec Solutions ...

Project - Saint-Nazaire - France
This site was part of a rehabilitation project in an urban area of the city of Saint-Nazaire (France). The contamination of the site was presumably caused by the previous activities of a gas plant. Two ESTD piles (respectively 1.500m³ and 2000m³ of soil) were built to treat the contaminated soil. Key Data Contaminants: THC (C10-C40), BTEX, PAH Max. Concentration: C10-C40: 33.000 ...

Sulfate-Enhanced bioremediation of BTEX - Case Study
Problem A former gas station in North Carolina contaminated groundwater with BTEX from a UST basin. The site is now in the median of a busy four-lane highway. Residents within 250 feet of the site use an irrigation well, prompting the need to conduct proactive remedial action. Site conditions of sand and clay above partially weathered bedrock and depleted sulfate concentrations within the plume ...
