  • Optical water quality assessment

    Scientists at the U.S. Geological Survey (USGS) have proven that measuring fluorescence could improve source water monitoring during a study of the McKenzie River in Oregon.  The study was designed to assess the amount, type and source of dissolved organic carbon that exists in all sources of drinking water. Dissolved organic carbon can react with chlorine during water treatment and form ...

  • Putting a price on water quality

    One way to clean-up water pollution is to award 'credits' to facilities that reduce their emissions. These credits can then be traded with other facilities to compensate for pollution outputs. This controls overall pollutions levels, while creating an economic incentive to reduce emissions. Research using models that simulate water quality has been used to establish the value of these credits and ...
