***WELCOME TO THE P2 LISTSERVER****
One use for selenium was in the plates of old rectifier systems that
converted alternating current to direct current. The military had a number
of systems that used this old technology. Battery chargers, some of the
old radar equipment, electroplating rectifiers, telephone system batter
chargers. These were all quite large systems and contained a pretty
healthy dose of selenium. Disposal of these items was not closely
controlled until the 1980s.
Selenium is a heavy metal and as such solubility is fairly low so if a
number of items were improperly disposed of as late as the 60s they could
still be leaching. As to where they might have been dumped, try storm
sewers or sanatary sewer areas in and around the above noted areas.

I have a colleague who is looking for clues as to potential sources of
elevated selenium levels in a military base sewer system. There are
apparently minimal industrial sources, i.e. no electroplating or coal
firing. The base is host to a large housing complex... any potential
Thanks in advance, I know there will be some good suggestions offered.
