I think that causes Global Warming (unless you are a lib or a Rock Band or Hillary or a tree Hugger)
Someone needs to map where the effluent actually ends up ... take some samples, grow some cultures and you know contact the EPA (HAAAAAAA HAAAAAA) do an Environmental Impact Study (and charge that $20,000 to the folks that operate the Bus)
This is actually a very Target Rich Environment!
