have there been any studies done on pharmaceutical traces/accumulation in the 
sludge?  A frightening amount of drugs are eliminated from a city 
population's body each day into the sewer... I know the prozac is now 
beginning to show up in Texas's water supply, but I've never heard anything 
about how much of it or other drugs might also be in sewer sludge. Treatment 
plants are not set up to deal with this type of contamination.
