Ramon Aravena

Ramon Aravena's current research focuses on groundwater contamination caused by agricultural and urban activities. He uses environmental isotopes as tracers to provide information about sources and processes that affect contaminants.

During his 20+ years experience, he has been involved in numerous groundwater studies in Latin America, Canada and the U.S.

Dr. Aravena is a research professor with 20 years experience in the application of isotope techniques in hydrology. He has been involved in numerous groundwater studies in Latin America, Canada and the U.S. related to evaluation of groundwater resources and groundwater protection.

His current research focus on groundwater contamination caused by agricultural and urban activities using environmental isotopes as tracers to provide information about sources and processes that affect nitrate and organic compounds in groundwater.
