Selenium treatment in wastewater has become a major challenge for a wide range of industries, including oil and gas, agriculture, and mining. Mining operations release selenium, that is naturally present in rocks and soils, into the environment primarily through surface water runoff and groundwater flow over the selenium laden waste rocks and tailings. Rangesh Srinivasan, CH2M Lead Process Engineer, will present a case study from one mine facility in North America to show how a full-scale biological fluidized bed reactor based water treatment plant helped treat selenium in mine water, during the Mine Water Solutions in Extreme Environments 2015 Conference, being held in Vancouver, Canada, this week.
The Mine Water Solutions in Extreme Environments 2015 Conference is being held in Vancouver, Canada, this week, bringing together engineers, corporate mining personnel, consultants, geoscientists, regulatory personnel, researchers, and mine/mill managers involved with water management, to discuss mine water management in extremely wet, dry, and cold climates and with extreme hydrogeological and geochemical issues. CH2M's Industrial Water Sector Global Service Technology Leader Ken Martins is presenting on bench-scale evaluation and feasibility study results for total dissolved solids (TDS) and sulfate reduction technologies in the Desert Southwest.

Managing water resources has become increasingly complex. Growing demands for water supply intensify the need for new sources, conservation, and reuse. These dynamics highlight the complex interrelationships among the links in the water management cycle, including source, supply, demands, treatment, re-use, and back to source again. CH2M HILL is at the forefront of developing integrated solutions for managing the entire water cycle, providing sustainable water supplies for human and ecological needs. Groundwater is a key part of the water management cycle. Numerical models have successfully been used to replicate some of the key features of hydrogeological systems to provide a better understanding of how systems work and how they respond to different stresses, in particular groundwater pumping from agriculture, mining, and gas activities. Numerical models can also be used to help quantify risks to water dependent assets. In the latest Access Water blog, CH2M HILL's John Poon, Thomas Neame, Carly Waterhouse, and Mark Favetta discuss the benefits of using groundwater numerical models to effectively manage water resources and supplies.
CH2M HILL is pleased to announce its participation in the second International Water Summit, hosted by Masdar and co-located with the 7th World Future Energy Summit at the Abu Dhabi National Exhibition Centre, January 20-22, 2014. Part of Abu Dhabi Sustainability Week, the Summit will gather leaders from the global water community in policy, business, academia, and science to accelerate the development of new sustainable water strategies and technologies for arid regions and bring to life the pressing issue of water security, sustainability, and the water-energy-food nexus. CH2M HILL is a global leader in developing and delivering sustainable water and energy solutions and is looking forward to participating in several key discussions.
A recent report by Morgan Stanley reveals that Australia is poised to be the biggest exporter of liquefied natural gas (LNG) in the world by 2017. Many Coal Seam Gas developers are working diligently to bring this new resource to market, which requires a reliable extraction and management of billions of gallons of coal seam water. CH2M HILL's Beccy Philby and Andrew Hodgkinson discuss methods for treating coal seam water, looking at solutions that are more energy efficient.
