Successful In Situ Remediation of Hydrocarbon Contaminated Soils in South Africa
Location: PepsiCo Frito-Lay Simba Isando, Gauteng, South Africa Use of the vehicle workshop area at the Frito-Lay Simba Isando plant was discontinued due to outsourcing of the distribution chain. An area in front of the wash bay bordered by the workshop and boundary walls had been heavily contaminated by hydrocarbon. This contamination was a mix of petroleum (PRO) and diesel (DRO) range organics ...

In-situ remediation of Polycyclic aromatic hydrocarbon contaminated soils - New Jersey, USA case study
Executive Summary A New Jersey utility company operated a regulator station on the site of a former manufactured gas plant in central New Jersey. The gas transfer station contained a large natural gas feeder main that fed major population centers in the southern part of the state. The regulator station contained an area approximately 3,600 ft2 contaminated to a depth of 1 meter with both PCBs and ...

Surfactant enhanced aquifer remediation (SEAR) using Ivey-sol surfactant technology
This paper will focus on the application of Ivey-sol non-ionic surfactant technology to improve the in-situ remediation of petroleum hydrocarbon contamination is soil and bedrock aquifers. Normally hydrophobic organic chemicals (HOC) exhibit limited solubility in groundwater as the contaminants tend to partition onto the soil and bedrock matrix. This partitioning can account for as much as ...

Remediation of silty-clay hydrocarbon contaminated site using Ivey-sol selective phase transfer technology
Earlier this year, Ivey International Inc. secured its first remediation project in Alberta using its Ivey-sol Selective Phase Transfer Technology (SPTT). This patented technology is being used to treat extensive soil and groundwater contamination at an active service station in Red Deer, Alberta. With a residential area nearby, the environmental sensitivity is relatively high. Unfortunately, ...

Improving the Predictability of Petroleum Brownfield Restoration
It’s no secret that the United States has an aging infrastructure problem. The public’s attention is focused on the repair of roadways and bridges, but there is also an ongoing initiative to address the existing infrastructure of legacy underground storage tanks, abandoned gas stations and truck stops, that are designated petroleum brownfields. As of July 2021, approximately 21 ...

A Citizen`s Guide to Bioremediation
What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...
