Research Interests
I have been actively engaged in environmental research focusing on water quality and quantity for over 20 years. My training is in environmental chemistry and the physics and I look for ways to increase water supplies through the safe use of reclaimed waters. My current research is related to the environmental and human health impacts of biologically active contaminants (e.g. pharmaceuticals, hormones and trace organics) found in reclaimed municipal wastewater and the associated impacts on soil, biota, and natural waters in contact with wastewater. My research is also looking for ways to assess and minimize detrimental effects and maximize benefits for food production and environmental protection when using municipal wastewaters for irrigation in both urban and agricultural settings. I am also involved in characterizing the environmental loading patterns of these compounds while finding low cost treatment alternatives to reduce their environmental concentration using byproducts capable of removing the compounds from water supplies.
