Risk Assessment and Terrestrial Plant Toxicity of Remediated Heavy Hydrocarbon Impacted Soil

Mentor: Bruce Rittmann
FURI: Fall 2018

The objective of the research was to determine the short-term ecological toxicity of ozonation byproducts on seed germination and compare those results to untreated soils. By helping define the eco-toxicity of ozonation techniques, this research will be used when considering the feasibility of field deployment of the previously established ozone techniques. Future research will focus on longer term ecological toxicity, the mutagenic properties of the soil after treatment, and the effect of ozone micro-doses on ecological toxicity as opposed to the bulk doses used here.

Heavy Hydrocarbon Removal using Ozonation Techniques

Mentor: Bruce Rittmann
FURI: Spring 2018

The objective of the research was to study the efficiency of heavy hydrocarbon removal using ozone gas. The research determined that doses of ozone gas in the soil can break down long-carbon chains into forms that are easily digestible by bacteria in the soil. By helping define the most effective loading rates and dosages, this research will be used to develop a field deployment unit that will be used to remediate contaminated soil in situ. Future research will focus on the potentially detrimental effect of high amounts of ozone on the soil bacteria community.
