Marie,
     The environmental laws in California are most definately strict.  It is
not out of the ordinary to see limits of copper discharge as low as .4ppm.
 As the laws have become more and more strict the PCB manufactures have been
able to stay in compliance.  Surprisingly many PCB shops have found
themselves not only saving money and reducing waste in the process, but also
streamlining their waste treat systems.  If you would like some information
on the systems and types of chemicals used feel free to contact me anytime.
