Incoming Quality Control of Water

摘要

It is well known and widely accepted in the water supply industry that the distribution system is not secure. Due to the potential for backflow events, cross connections, corroding pipes, groundwater infiltration and biofilm events, the water contained in the distribution system is not immune to becoming recontaminated after leaving the treatment plant. An added danger is the potential for deliberate contamination due to terrorist activities known as backflow attacks. Much attention has recently been placed on the vulnerability of the U.S. drinking water supplies to assault by terrorists.
