Homebrew PCBs

At the risk of taking this somewhat off-topic thread even further off, 
consider how much clorox bleach we dump into our septic systems each 
week doing laundry...  I can remember back in my beer brewing days 
that it only took a few drops of clorox to kill all the bacteria in a 
10 gallon fermenting carboy. I'm no chemist, and except for the issues 
with copper as mentioned by other posters, I don't think a few ounces 
of FeCl3 now and then compare with the rest of the daily crap we 
polute our septic systems with.  

Just my nickle's worth,
Jim
