Antonio Cardona is a researcher and consultant in hydrogeology and water resources with a sound background in the fields of hydrogeology, hydrogeochemistry and statistical analysis of hydrogeological data. With a Ph.D. and M.Sc. in hydrogeology and more than 25 years of experience as a consultant, academic researcher and teacher, he brings a strong scientific and technical background to his work. He has over 25 years of research experience on matters related to the chemistry of water resources and the origin, transport, and fate of inorganic contaminants in groundwater and surface water systems. Dr. Cardona has also authored or coauthored 40 peer-reviewed papers, 2 books, 13 chapters in books, about 35 Conference Publications (with figures and tables), more than 50 abstracts in Conference Publications and more than 90 oral presentations in Congress and Symposia; currently his investigations have been cited in over 750 research papers and thesis. Antonio has substantial experience with problems related to the naturally occurrence of fluoride, arsenic, heavy metals, radionuclides and groundwater age-dating. Expert in geophysical surveys, drilling, packer-test and pumping test supervision. For environmental assessment, has considerable experience in risk analyses for groundwater vulnerability (numerical models or index methods). He is an accredited national researcher by the National Research Institute of México (SNI) since 1998 and since 2003 recognized as a Qualified University Professor by the National Ministery of Public Education (SEP) of Mexico.
