“…Though many of the spills were relatively small (<10 barrels), nearly all affected agricultural land, including cropland, pastureland, and natural grasslands. The petroleum hydrocarbons (PHC) in the crude oil reduce productivity potential of the land (Eom, Rast, Veber, & Vasseur, ; Issoufi, Rhykerd, & Smiciklas, ; Yi, Park, Munster, Kim, & Sung, ), necessitating contaminant removal (i.e., soil remediation) to return to pre‐spill levels. Returning these lands to productivity (i.e., soil reclamation) is crucial for long‐term food security, especially as other important agricultural land in the state is declining in productivity due to salinity and sodicity issues (Seelig, ).…”

Crop production on heavily disturbed soils following crude oil remediation

Cropland contaminated by crude oil typically requires remediation before it can meet pre‐contaminated productivity potentials. Remediation strategies focus on removing the contaminant, but they also often alter soil properties, which affects the capacity of the land to sustain agricultural production. This research describes crop production following the remediation of crude oil contaminated soil in North Dakota, USA using two different strategies, a modified land‐farming technique and ex situ thermal desorption. Wheat (Triticum aestivum L.) and field pea (Pisum sativum L.) were grown in soils treated by both of those techniques, as well as mixtures of each treated soil with native topsoil. Across three growing seasons of comparisons to native topsoil, crop production was 61 ± 20% lower in the modified land‐farm soils and 52 ± 25% lower in thermal desorption‐treated soils; these yield declines were likely associated with reduced soil organic carbon levels. Notably, the soil mixtures had higher soil organic carbon levels and matched the native topsoil in both yield and protein content, suggesting that soil mixing may be a promising tool in cropland soil reclamation. Overall, these findings reinforce that crop production on reclaimed land is linked with soil properties, so long‐term reclamation success requires a holistic approach to soil management.

Soil pollution by oil products is one of the most obvious environmental problems that Romania has been facing in recent years. Given the alert pace of use of petroleum products and for meeting energy needs, it is noted that both in Romania and abroad there are reported accidental oil spills to soil or water, which causes economic, social and environmental issues. In this paper we propose a review of the particularities of soil pollution with liquid petroleum products and opportunities for remediation. The analysis of remediation processes of soils contaminated with liquid petroleum products highlights the advantages and disadvantages of each method. The analyzed samples were subjected to thermal remediation methods: combustion and thermal desorption and one of the chemical processes, succesive extraction with solvents. The results of these experimental data allow us to conclude that the used method is efficient and can be applied at industrial level with high efficiency.

“…This is in agreement with Terefe et al (2008) who suggested that silt-and clay-sized particles formed sand-sized aggregates through a cementing effect at thermal temperatures of 300-500 °C. However, a lower temperature (250 °C) or shorter thermal treatment duration (10 min) may not significantly change the composition of soils as observed by Yi et al (2016). The pH of HOC after LTTD was increased (p < 0.05) and closer to neutral, as compared to base soil and HOC before treatment.…”

“…According to the treatment temperatures, they are classified as low-temperature (100-350 °C) and hightemperature (350-600 °C) thermal desorption by physical separation, and incineration (600-1000 °C) which destroys contaminants (Falciglia et al, 2011). On one hand, limited reusability of residual soil after treatment and high initial setup expenses restrain the practicability of high-temperature thermal desorption (HTTD) (Yi et al, 2016). On the other hand, low-temperature thermal desorption (LTTD) treatment represents a feasible method for the remediation of oil contaminated soils which both achieves relatively complete remediation and keeps soil health at the maximum extent.…”

Remediation of oil-based drill cuttings using low-temperature thermal desorption

Drill cuttings are generated during the exploration and extraction of oil and natural gas. Due to the use of oil-based muds (OBMs) during drilling process, large amounts of oil-based drill cuttings (OBDCs) are produced. Such hazardous waste contains a relatively high content of petroleum hydrocarbons (PHCs). The effective removal of PHCs from OBDCs has attracted ix Acknowledgement This thesis reflects the final part of achievements that I have made in my M.Sc. study at the University of Northern British Columbia (UNBC). First and foremost, I would like to express my sincere gratitude to my co-supervisors, Prof. Jianbing Li and Prof. Min Zhao, for their patience, understanding, insightful instructions, and support throughout my study and research. Without their guidance and support, it would be impossible for me to complete this research. What I have learned from them will benefit my future career and life. Moreover, I would like to thank Prof. Ronald W. Thring for serving as my supervisory committee member. I greatly appreciate his insightful comments, guidance and discussions. I would like to express my appreciation to Erwin Rehl and Charles Bradshaw working in Northern Analytical Laboratory Service (NALS) at UNBC for their patience and help on developing and refining my analytical methods as well as on analyzing my experimental samples. I also thank Conan Ma working at UNBC Chemstore for his support with sample delivery and lab materials supply. Special thanks go to Prof. Joselito M. Arocena, a great soil scientist, who was my previous committee member. I am grateful to his kind guidance and help to my graduate study and life. My gratitude also extends to the people in my lab group for their helps, valuable discussions and every joyful moment; they are Guangji Hu and Yuan Tian. Their kind sharing knowledge, skills and thoughts helped me a lot for the completion of this thesis. Finally, I would like to dedicate this work to my family, my parents, grandma and my older sister, for their unconditional supports and understanding. Without their supports and encouragement, I would not have come to UNBC and complete my Master's degree.
