Hydrocarbon-Contaminated Soil Remediation
Hydrocarbons are organic compounds composed of hydrogen and carbon atoms and are the building blocks of many fossil fuels. Petroleum products, such as gasoline, diesel, and oil, are major sources of hydrocarbons. Spills or leaks of these products can result in soil contamination, and if left unaddressed, can have significant environmental and health impacts. In this article, we will discuss the ...

Monitoring of reservoir feed for hydrocarbon contamination - Case Study
APPLICATION Monitoring of rural watercourse feeding a small reservoir to detect contamination from farm or food processing facilities. CUSTOMER Water Company, SW England PROBLEM Persistent small contamination events had put the reservoir which feeds a drinking water treatment plant at risk. Low level contamination preceded a large event in late ...

Raw water intake monitoring - Case Study
The Situation Hydrocarbons in municipal water supplies, including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through ...

Monitoring a high iron and manganese content borehole for hydrocarbons - Case Study
APPLICATION Monitoring a borehole for contamination from a known petroleum spill. CUSTOMER Water Company, UK PROBLEM The customer wished to monitor hydrocarbon levels in a borehole for drinking water. The customer had attempted to use a UV based system but found that the system would only last a matter of a few days before ferric and manganese deposits stopped the system from ...

Site Characterisation in Support of Monitored Natural Attenuation of Fuel Hydrocarbons and MTBE in a Chalk Aquifer in Southern England
This Case Study Bulletin describes a research project, which was carried out to determine whether monitored natural attenuation was a viable option for managing fuel hydrocarbon contamination in a chalk aquifer in southern England. The research, which was carried out from February 2000 to March 2001, was undertaken by the University of Sheffield on behalf of TotalFinaElf at a petrol filling ...

Application of first-order reliability method to modelling the fate and transport of benzene in groundwater
Parameter uncertainty plays a significant role in decision making regarding groundwater contamination and remediation, especially for non-conservative chemicals. This paper presents a probabilistic screening model to accommodate parameter uncertainty in the aquifer media, and physical–chemical parameters, using the first-order reliability method (FORM). The application of the developed model is ...

Proof of concept for the use of macroinvertebrates as indicators of PCB contamination in Lake Hartwell
The U.S. Environmental Protection Agency (EPA) develops methods and tools for evaluating risk management strategies for sediments contaminated with polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and other legacy pollutants. Monitored natural recovery (MNR) is a risk management alternative that relies on existing physical, chemical, and biological processes to ...

Mineral oil bio-degradation within a permeable pavement: long term observations
ABSTRACTThe paper reports on the first 300 days of a research project conducted at Coventry University, which has focused on the ability of a permeable pavement, reservoir structure to retain and treat petroleum-derived pollutants through in situ microbial bio-degradation. The research has required the construction of a full-scale model permeable pavement in the laboratory, which has been ...

Performance assessment of pilot horizontal sub-surface flow constructed wetlands for removal of diesel from wastewater by
Scirpus grossus One of the appropriate development technology options for the treatment of wastewater contaminated with diesel is constructed wetlands (CWs). Throughout 72 days of exposure, sampling was carried out for monitoring of physical parameters, plant growth and the efficiency of total petroleum hydrocarbon (TPH) removal, as an indication for diesel contamination, to assess the pilot-scale performance. ...

Tips for refinery gas analysis
Refinery gas analysis (RGA) is an important application in oil and gas which characterizes the gases produced during crude oil refining, including stack emission, flame and reformate streams. The challenge in RGA analysis is the reliable analysis of variable sources and compositions of gases produced via fluid catalytic cracking (FCC). The analysis must be quick and accurate to allow engineers ...

Fast BTEX and methylnaphthalene bioremediation
Petrox Petrox and Methylnaphthalene Bioremediation Site Summary Petrox micorbes accelerated BTEX and methylnaphthalene bioremediation at a former fueling station in Florida. After a leaking tank underground storage tank (UST) was removed Petrox micorbes were applied to the groundwater. A temporary well showed high concentrations of BTEX, methylnaphthalene isomers, and total recoverable ...

PRP: The Proven Solution for Cleaning Up Oil Spills
Originally published in 2006 at https://spinoff.nasa.gov/Spinoff2006/er_1.html Originating Technology/NASA Contribution The Exxon Valdez, an oil tanker exporting millions of gallons of oil, ran aground just after midnight on March 24, 1989 in Alaska, creating what is, to this day, the worst environmental disaster in American history. The affected area of coastal Alaska continues to feel the ...
