The Metro District serves approximately 1.5 million people from a 380-square mile service area that includes Denver, Arvada, Aurora, Lakewood, Thornton, Westminster, and more than 45 sanitation and water and sanitation districts. The Metro District treats about 160 million gallons of wastewater a day. After treatment, the water is discharged into the South Platte River, where it provides nearly ninety percent of the water in the River for nine months of the year.

Environmentally friendly technique recovers metals from wastewater August 26, 1994 By Lynn Yarris, LCYarris@lbl.gov An environmentally benign technique for removing and recovering metals from waste water that is being developed by LBL scientists could be used to clean up abandoned open-pit mines such as the Berkeley Pit in Butte, Montana. Richard H. Fish, a chemist with the Energy and Environment Division, led the research into chemically modifying tiny polystyrene beads with a special type of organic molecule called a ligand so that they recognize and tightly bind to certain metal ions. The beads are then removed from water and the metals are recovered from the beads. Located in an ore-rich section of southwestern Montana, the Berkeley Pit is a vast open-pit mine that was closed in the 1980s and has been slotted by the U.S. Department of Energy as a "demonstration site" for environmental reclamation. Following the shutdown of mining operations, the Berkeley Pit was filled with some 17 billion gallons of water. Suspended in this water are substantial concentrations of various types of metal ions, including iron, copper, zinc, manganese, magnesium, and aluminum. "Recovering the metals in the Berkeley Pit could be worth billions of dollars," says Fish. "Even if the recovery of the metals were not in itself economically viable, it would help defray the costs of cleaning up the pit."

The results of our present wastewater treatment practices can be seen in eutrophic ponds choked with algae and plant growth, streams and rivers where most of the fish and amphibians are diseased or gone, and groundwater that is too polluted to drink. Fortunately, we are becoming aware of our destructive patterns. With this awareness comes a responsibility to design new ways of living. This does not, however, imply a need to spend more money for greater wastewater purification levels. The standard solution has been to built complex, expensive municipal treatment plants which merely shuffle the problem from one arena to the next; from the pollution of groundwater and local surface water by septic systems to the pollution of rivers, lakes, oceans and landfills by municipal treatment plant effluent and sludge. With the elimination of federal funding for wastewater treatment, this solution has become obsolete.

cwrs@dal.ca Welcome to the On-Site Wastewater Reasearch Program Information page. CWRS has been active in on-site research since 1981. Installation of on-site systems in Nova Scotia is a significant industry. Currently some 5,000 applications for approval to install on-site systems are made annually in Nova Scotia. The majority of these applications are for individual houses, but they also include other establishments, such as schools, campgrounds, apartment buildings, industrial developments, and mobile home parks. The annual capital cost of these on-site systems probably exceeds $10 million, and they represent an essential component of a total building cost in excess of $250 million per year. Properly operating on-site systems can provide significant cost savings in comparison with central services. A typical on-site system in Nova Scotia costs $3,500, compared with an average cost in excess of $15,000 per connection to install central services. Operating costs of on-site systems are also lower than for central systems. The use of on-site sewage disposal systems to serve exisiting and future developments will continue for the foreseeable future. Development of improved systems , based on utilization of state of the art materials and research results that provide a better understanding of the functioning of on-site systems , and their environmental and health impact, will insure that the immense investment can be protected and enhanced.

Wastewater Pollution in China by Kris Min ABSTRACT Wastewater pollution has always been a major problem throughout the world. The lack of suitable water used for drinking, agriculture, farming, etc. has declined through the years. With a shortage of water throughout the world, proper methods of treating and recycling water is the key goal in sustaining our limited water resource supply. Geographically speaking, the wastewater pollution within China has affected the environment, society, and agriculture. The water pollution crisis in China has brought up an issue of efficient wastewater treatment methods to help alleviate their problems. Throughout this paper, we will discuss the topics on the effects of wastewater pollution towards the environment and the society (health factors, agriculture, economic impacts, etc). At the same time, proposals for wastewater treatment procedures and facilities to help the water crisis in China will be discussed. INTRODUCTION The lack of clean water has always been an issue of environmental concern all over the world. This environmental issue is mainly stressed in developing countries today. The main sources of water pollution are: industrial (chemical, organic, and thermal wastes), municipal (largely sewage consisting of human wastes, other organic wastes, and detergents), and agricultural (animal wastes, pesticides, and fertilizers) (Brower et.al, 1990). For the past several years, China has been affected with the water pollution crisis. Three examples of wastewater pollution crisis in China are the City of Tianjin, the Chao Lakes and Xian City.
