摘要：	Transportation agencies are required to treat roads for dust and ice control to ensure adequate safety for travelers. This is commonly achieved through application of solid and liquid chemicals. These materials can be conventional rock salt, brine from rock salt, natural brine, or oil and gas brine. Due to the high cost of treating roads for the removal of snow and ice, in states with active oil and gas wells such as New York, the potential for using this brine to control dust or ice on roads is currently being explored. Environmental concerns exist over the use of conventional oil and gas brines due to their potential high total dissolved solids and metals concentrations1,2 They can also be elevated in organic compounds and can contain certain chemical additives3. If conventional or unconventional oil and gas brine is applied to roadways for dust or ice control, there is the potential for runoff to impact receiving water or roadside soil. The environmental impact of the leaching of chemical components from soil impacted with oil and gas brine applied for transportation purposes is unknown. The goal of this work was to determine the potential for components found in oil and gas brine to leach from soil to groundwater. The potential for components found in other alternative brines (agricultural based and plant based) was also investigated. Three brines were characterized based on their physical and chemical parameters. Toxicity characteristic leaching potential (TCLP) tests were conducted to compare the potential for the release of metals from three brines commonly applied for dust and ice control in New York. Results show that the plant-based brine has the least potential to leach metals from a soil/brine mixture, while the oil-based brine has the highest potential to impact the environment through the leaching of metals. Results from the leaching tests for all experiments show that the concentrations of certain metals would be found in groundwater that are elevated above the maximum contaminant levels set forth by the USEPA.
