I work in municipal water and wastewater treatment. We need to do exams and courses in a three year period to maintain our certification. However! In college I took environmental technology as my major.

And I'm cool with most music! Your last two links didn't work though! D:

Let me know if they work now! 

Ohhhh. That makes sense then x) At least you're making sure the water is clean, and treated.
