The theme of my research is the conflict between expanding demand for freshwater resources to provide drinking water for the growing population and irrigation water for agriculture, and simultaneous pressures to prevent pollution and leave enough water for natural ecosystem functions. These combined pressures define the need for sustainable water resource management.Protection and management of water resources requires the assessment of ecosystem degradation resulting from human activities, and the implementation of measures for the reduction and amelioration of current impacts. Hydrologic systems of particular interest include groundwater resources that are threatened by uncontrolled releases of anthropogenic contaminants such as petroleum hydrocarbons and chlorinated solvents, and surface water bodies such as rivers, lakes, and wetlands whose ecological integrity has been compromised by excess nutrient loading.Specific recent research objectives include:1. quantify the benefits of partial removal of aquifer contaminant source zones (as no remediation technology is able to achieve complete contaminant removal),2. evaluate the effect of agricultural land use within a watershed on relative contribution to overall watershed runoff and nutrient export, and3. develop methods for in-situ quantification of mass fluxes of nutrients and chlorinated hydrocarbon contaminants in both groundwater and surface waters. These techniques have great potential to contribute to the Total Maximum Daily Load (TMDL) program mandated by the Clean Water Act.
