The copper industry provides a great deal of assistance related to corrosion, such as playing a major role in developing three non-leaded selenium and bismuth containing brass alloys, which may be
substituted for leaded brass alloys in plumbing castings. The Copper Development Association Incorporated (CDA) recently organized a symposium for technical personnel, in companies which produce plumbing tube and fittings. Six experts on pitting of copper presented their views of the field. Together with the State of Connecticut it has developed data on copper in stormwater runoff from a copper roof at the University of Connecticut. The results showed that by the time the stormwater flowed
through the campus stormwater systems, it was no longer acutely toxic to a sensitive aquatic organism.
