This link tells us about the recent proposal that urine should be collected separate from other wastewater (no more standing up guys). What is cool about this is the proposal is that materials be recovered from the collected urine and sold as a cost recovery. This links nicely to our discussion on the chlorination of municiple waters.

This second link is very cool since it is a very good study on what can be detected in our waterways as a result of our wastewaters. As the authors say ...
The most frequently detected compounds were coprostanol (fecal steroid), cholesterol (plant and animal steroid), N,N-diethyltoluamide (insect repellant), caffeine (stimulant), triclosan (antimicrobial disinfectant), tri(2-chloroethyl)phosphate (fire retardant), and 4-nonylphenol (nonionic detergent metabolite).

This makes for an interesting insight into the persistence of our chemical wastes relating to organc chemistry.
