Petroleum Hydrocarbons in Wastewater
A wastewater treatment company established and operates an oil/water separation facility on a multi-acre industrial site in Northern California. Its purpose is to recycle oil products for profit while at the same time provide a wastewater treatment service for industries based in Northern California. The oily water mixes processed by the company are obtained from tanker bilges, contaminated ...

Characterization and treatability of a contaminated soil from an oil exploration zone
Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions (0.5%) ...

Validation of New VPH GC/MS Method using Multi-Matrix Purge and Trap Sample Prep System
Abstract The Massachusetts Department of Environmental Protection (MassDEP) developed the “Method for the Determination of Volatile Petroleum Hydrocarbons (VPH) by Gas Chromatography/ Mass Spectrometry” to measure the collective concentrations of volatile aliphatic and aromatic petroleum hydrocarbons in aqueous and soil/sediment matrices1. The previous method for VPH determination ...

Identification and distribution of petroleum hydrocarbons in sediments, seawater and Ruditapes decussatus collected from a Mediterranean Sea site
The goal of this study was to assess the degree of pollution in three different matrices in the navigation canal of Tunis. Using appropriate techniques we showed that Total Hydrocarbons (THCs) in the sediment samples ranged from 160 mg/kg to 5500 mg/kg. But in the seawater the THCs ranged from 2 mg/L to 80 mg/L due to petroleum hydrocarbons. The Total Aliphatic Hydrocarbons (TAHs) in R. ...

Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge
Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

Enhanced bioremediation of groundwater using in-well methods – Case Study
Overview: This white paper provides a comparison of two groundwater treatment methods that are used to facilitate remediation of floating and dissolved petroleum hydrocarbons in groundwater. Both methods have some merit. However, United Remediation Technology (UniRemTech)’s Wellboom ™ can provide a faster and longer lasting solution due to its composition of absorption and in-situ ...

Surfactant–enhanced remediation of soils contaminated with petroleum hydrocarbons
An experimental programme was undertaken to reclaim the soils contaminated with petroleum hydrocarbons. Two types of locally available soils, clay with low compressibility and poorly graded sand, were chosen for the study. Both the soils were contaminated with varying percentages of used engine oil and gasoline. Anionic surfactant Sodium Dodecyl Sulphate (SDS) was used to reclaim the contaminated ...

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 ...

Waterloo Barrier Containment Cell - Case study
Problem A containment system was required to prevent a plume of non-aqueous phase petroleum hydrocarbon from migrating into a river adjacent to a former MGP site in Amsterdam, New York. ...

Brownfield Site Phytoremediation for Oil Company - Case Study
The site was a petroleum tank farm from the early half of the 20th century. Contaminants on-site include petroleum hydrocarbons, benzene and ethylbenzene, and PAHs naphthalene and 2-methylnapthalene. Most contaminants are in subsurface and groundwater, with the exception of PAHs that extend from the surface to ...

Monitoring leaks in Heat exchangers - Case study
The Situation A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face ...

Site Description – Crude Oil Contamination from Oil Fields
Site Location: Offshore oilrig in Gulf of Mexico Site Description: The sludge produced from an offshore oil well drilling operation was temporarily stored on a barge. The sludge was then transferred onshore for disposal at Class #1 landfill. The waste material was composed of approximately 60% oil, 20% solids and 20% water Starting Contamination Levels: The average Total Petroleum Hydrocarbons ...

Cleanup levels at an oil distribution and storage station in eastern central Mexico determined from a health risk assessment
The subsoil of an oil storage and distribution station located in eastern central Mexico was characterised in terms of some fuel fractions and metals. The site was found to be contaminated mainly with total petroleum hydrocarbons (TPHs) at a concentration higher than that legislated in Mexico. The presence of BTEX (benzene, toluene, ethylbenzene and xylenes) and 11 of the 16 USEPA polynuclear ...

Cost-Effective Destruction of Petroleum Hydrocarbon Contaminants with Expedited Residual Mass - Smear Zone (LNAPL) Destruction under Anaerobic Conditions via Biostimulation
One-year program to evaluate biostimulation as a LNAPL remedial strategy using TPHenhanced. Program goals include 1) enhance respiration of indigenous heterotrophic bacteria 2) expedite residual source mass (LNAPL) solubilization and 3) enhance dissolved-phase petroleum hydrocarbon (PHC) destruction. Former automobile fueling-service facility from 1950 to 1982. PHC release documented during 2003 ...

Environmental and health risk assessment of an oil contaminated site in the Mexican tropical southeast
The aim of the present study was the environmental and health risk assessment of the oil contaminated soil in the Mexican tropic. The case is based on the total petroleum hydrocarbons (TPH) and polycyclic aromatic (PAH) soil contamination resulting from the activities of the oil industry over 70 years. The results of this study were estimated using CalTOX, a multimedia exposure model. The ...

Enhanced bioremediation of crude oil in polluted beach sand by the combination of bioaugmentation and biodiesel
Biodiesel produced from rapeseed oil was used as a cost-effective and sustainable agent to enhance crude oil biodegradation in sand microcosms. The initial concentration of crude oil and total petroleum hydrocarbon (TPH) was 20,000 and 18,750 mg/kg, respectively. The mass ratio of biodiesel to crude oil was 0 (designated T1), 1:10 (designated T2), 1:4 (designated T3), and 1:2 (designated T4). ...

Microbial Degradation of Petroleum Hydrocarbon Contaminants: An Overview
Introduction Petroleum-based products are the major source of energy for industry and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. The amount of natural crude oil seepage was estimated to be 600,000 metric tons per year with a range of uncertainty of 200,000 metric tons per year ...
