Professor McCray's research focuses on chemical transport in hydrologic systems, and generally utilize some combination of field, laboratory, and modeling work. Current projects include: green infrastructure for treating storm water and recycled water in constructed urban streams, potential release and transport of metals in groundwater due to CO2 leaking into overlying aquifers during carbon sequestration; impact of the mountain pine beetle on hydrology and chemical transport in Rocky Mountain watersheds; transport, interphase mass-transfer and remediation of hydrocarbons in groundwater; chemical and bio remediation in fractured rock aquifers; using polymer solutions to enhance delivery of remediation agents to lower-permeability media; fate and transformation of nitrogen, pharmaceuticals and other emerging organics in the vadose zone during soil-based wastewater treatment; nitrogen contamination of springs in western Florida, and joint sustainability of water resources and petroleum-energy production in the arid west.
