Travis Tasker Profile ImageDr. Travis Tasker, Postdoc Fellow in the Environmental Engineering department, published three papers during the Fall 2018. One paper was published in the Journal of Chromatography A and was titled "Applications of thermal desorption coupled to comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry for hydrocarbon fingerprinting of hydraulically fractured shale rock." The paper highlights a new technique for characterizing hydrocarbons from shale cores. The method provides a more detailed hydrocarbon analysis of reservoir rocks than what is currently implemented in industry. This work was in collaboration with lead author Paulina Piotrowski and co-authors Frank Dorman and William Burgos at The Pennsylvania State University. 

Dr. Tasker also published a paper titled "Radium attenuation and mobilization in stream sediments following oil and gas wastewater disposal in western Pennsylvania" in the journal of Applied Geochemistry. The study showed that radium is accumulating in river sediments downstream of centralized wastewater treatment facilities due to ineffective oil and gas wastewater treatment. This work was in collaboration with researchers at The Pennsylvania State University, US Geological Survey, and Dartmouth College. 

In addition, Dr. Tasker published a paper titled "Accuracy of methods for reporting inorganic element concentrations and radioactivity in oil and gas wastewaters from the Appalachian Basin, US based on an inter-laboratory comparison" in the journal Environmental Science: Processes & Impacts. The paper highlights the accuracy of oil and gas waste analyses based on an inter-laboratory comparison with government, commercial, and academic labs throughout the world. The study showed that numerous methods can be used to measure major cation, minor cation, and anion concentrations in O&G wastewaters with relatively high accuracy while trace metal(loid) and radioactivity analyses in liquids can be over 20% different from the true value.
