The availability of clean water is already a major issue, and will become a ‘water crises’ if we do not act urgently
Access to Water Remains Insufficient, Especially for thePoor
Issues specific to the Desert Southwest Southwest
• Inefficiency of the designed water recycle facility.
• Education to the public is not powerful enough to lead people to use recycled water - "Oh, Icky reclaimed water!"
• Water is being used faster then the water cycle can restore it.
• Treated water is often subsidized, exacerbating the problem.
• Groundwater and surface water sources have become polluted and can no longer be used without required extensive treatment.
• New water sources often involve pumping water long distances, desalination, wastewater reuse, and or rationing.
Hospital waste water effluent has many constituents that need to be treated before post-hospital use:
pathogens and other biologic agents
X-ray processing effluents
