Title : The 21st Century Water Quality, Safety and Monitoring Issues
Abstract :

Water resources are extremely important for the 21st century. Today, there are more and more pollutants discovered in rivers, lakes, and groundwater etc. There are approximately 35,000 different types of pesticides and poisons used throughout the world and as a result drinking water has been widely contaminated.  To be considered a safe and acceptable source of drinking water, reservoir and river waters must be free from contaminants that present an acute health risk and also meet the acceptable levels of chronic health toxicities. Hence, water quality, safety, and its monitoring process are key factors for human health.

Water quality standards are the basis for protecting and regulating the quality of surface and drinking waters in different countries. For surface waters, such standards are benchmarks established to assess whether the quality of rivers and lakes is adequate for drinking, agriculture, industry and other uses.

Well equipped analytical laboratories managed by highly qualified personnel are required for testing water quality. Organic, wet chemistry, trace element, and microbiology tests are carried out in the lab. Recently, new instruments and developed advanced methodologies provide improved capabilities for detecting large numbers of newly discovered and potentially harmful contaminants in water at very low levels.

This presentation will discuss the details of water quality, safety, and monitoring technologies including the areas of organic, inorganic, microbiology and biology.

 

Biography :

Dr. George Yang Zhaoguang is currently a Principal Research Scientist and Vice President, Centre for Advanced Water Technology (CAWT), Singapore. He has 30 years of R&D experience since graduating from Central-South University of China. He holds a Ph.D. degree from the University of Nevada-Reno and a M.S. degree from South Dakota School of Mines and Technology, USA. Dr. Yang has extensive experience in water and wastewater treatment technologies, analytical and water chemistry, biotechnology, water quality and security. There are more than 100 publications under his name.
In CAWT, he performs research, administers and operates research analytical laboratories to conduct drinking water tests, research projects, and supports regional government agencies and industries. In 1998, he joined Environmental Technology Institute (ETI) of Singapore as the manager of Research Analytical Laboratories, and led the team to be one of the best in the region. Before joining ETI, Dr. Yang has worked in various institutes and industries. He was a research associate at the Generic Mineral Technology Center for Mineral Industry Waste Treatment and Recovery, USA. While working at the Energy and Environmental Engineering Center, Desert Research Institute, USA, he was involved in the State of Nevada Air Pollution Study and the Snow Chemistry Study of the Cascade-Sierra Nevada Mountains. During his service with Environmental Services Division of Westinghouse Electric Corporation, USA, he has held various positions including senior chemist, laboratory supervisor, and senior engineer. He designed, developed, and acted as lead engineer for major efforts. Dr. Yang has established several laboratories, as well as designed, constructed and managed several large wastewater treatment facilities in the United States and Asia.Dr. George Yang Zhaoguang is currently a Principal Research Scientist and Vice President, Centre for Advanced Water Technology (CAWT), Singapore.
