Re: Copper and Lead in the Sewers

Could be several sources.  Plumbers, jewelers, welders, etc.

Subject: Copper and Lead in the Sewers

Has anyone done a survey of industries that may be present in a smaller
town (e.g., automobile repair) that may be responsible for elevating levels
of copper and lead in a small sewage treatment plant discharge?  I know
that mercury, molybdenum, cadmium, silver and certain organics have been
tracked to specific source.  Is there a publication on sources for copper
and lead?  Thank you.
