Short CV Dr Ed Mroczek has been a practising geochemist for 26 years in all areas of geothermal chemistry for clients in New Zealand, Indonesia, Turkey, Philippines and Japan. He has published 40 papers and conference abstracts, over 100 confidential client reports and 2 provisional patent applications. He has had extensive experience in the design and running of large-scale field experiments and laboratory scale hydrothermal experiments to determine reaction rates of geothermal fluids in reinjection aquifers. His present work includes geothermal resource evaluation and assessment, production chemistry monitoring and environmental geochemistry.
