Fast Creosote Bioremediation Results
Creosote bioremediation was recently demonstrated by a user of a custom blend of CL Solutions organisms. The environmental consulting firm applied the microbes to finely shredded wood that had been saturated with creosote. The initial testing results after bioaugmentation showed a reduction of the creosote concentration by 57% in just 7 days. The concentration measured as total recoverable ...

Acute toxicity of chemically and mechanically dispersed crude oil on juvenile sea bass (Dicentrarchus labrax): Absence of synergistic effects between oil and dispersants
The goal of this experiment was to assess the relative acute toxicities of mechanically and chemically dispersed oil (Crude Arabian Light) in controlled conditions. Juvenile sea bass (Dicentrarchus labrax) were exposed to four commercial formulations of dispersants (Corexit EC9500A, Dasic Slickgone NS, Finasol OSR 52, Inipol IP 90), to mechanically dispersed oil and to the corresponding ...

Comparative effects of biological and chemical dispersants on the bioavailability and toxicity of crude oil to early life stages of marine medaka (Oryzias melastigma)
We assessed the bioavailability and chronic toxicity of water‐accommodated fractions of crude oil (WAFs) and two dispersants plus dispersed crude oil (chemical dispersant + crude oil, CE‐WAF, and biological dispersant + crude oil, BE‐WAF) on the early life stages of marine medaka, Oryzias melastigma. Results showed that the addition of the two dispersants caused a three‐ and four‐fold increase ...

Oil in frac water testing
The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

Can I extend the range of the TPH in Soil kit by dilution?
The pocket colorimeter kit by Hach offers an immunoassay method to measure TPH (Total Petroleum Hydrocarbons) in soil samples – a useful indicator of petrol pollution or contamination in soil. For areas of heavy contamination the range of the test can be extended by dilution during the soil extraction step. The first stage in the test is to extract the TPH from the soil into a liquid, ...

Toxicity of fuel contaminated soil to antarctic moss and terrestrial algae
Fuel pollution is a significant problem in Antarctica, especially in areas where human activities occur, such as at scientific research stations. Despite this, there is little information on the effects of petroleum hydrocarbons on Antarctic terrestrial biota. This paper demonstrates that the Antarctic mosses Bryum pseudotriquetrum, Schistidium antarctici, Ceratodon purpureus and the Antarctic ...

Portable Infrared Analyzers Provide On-Site Measurement of Oil and Grease Levels in Hydraulic Fracturing Water
The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off-site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote laboratory results to determine the oil level can take several days to a ...

Comparative analysis of the outflow water quality of two sustainable linear drainage systems
Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all ...

Accurately Measure Hydrocarbon (Oil/Grease) Levels in Produced Water in Under 15 Minutes
Determining total hydrocarbon or oil/grease levels to ensure compliance with regulatory permit requirements for discharging produced water is a worldwide problem facing the oil and gas industry. Ensuring compliance with these regulations and avoiding fines for non-compliant discharges requires more frequent wastewater measurements to determine the total hydrocarbon concentration. The portable ...

Cementing the PC MACT
On September 9, 2010, the U.S. EPA promulgated the final amendments to the National Emissions Standard for Hazardous Air Pollutants from Portland Cement Manufacturing Industry (40 CFR 63 Subpart LLL), also known as the PC MACT. EPA’s self-proclaimed “historic” rulemaking includes some important implications for cement manufacturers and other sources that may be subject to ...
