Mānoa’s Water Resources Research Center Interim director Chittaranjan Ray and Junior Specialist Philip Moravcik received a competitive $500,000 grant from the United States Department of Agriculture’s National Institute for Food and Agriculture to study the uptake of pharmaceutical compounds by edible plants under differing conditions of soil moisture stress.
Ray and Moravcik will be looking at pharmaceuticals typically found in treated wastewater. Radio-labeled compounds will be used to examine the uptake of these compounds by plants. The results will have implications for the increased reliance on wastewater to irrigate in places where the availability of other water is in decline.
Ray and Moravcik are collaborating with Clinton Williams of the USDA Arid-Land Agricultural Research Center in Arizona. Comparative evaluations will be made between Hawaiʻi and Arizona conditions.
Ray’s research focuses on chemical and pathogen transport in soils and ground water, water supply, and riverbank filtration.
