What's in the Air Ends up in Our Water

Hey, folks! Just a quick note to share what we've found.
Normally our rain water is beautifully clear. Pristine and perfect.
Tonight this is our rain water.
Odd color for rain water, right?!!
So, tell me. . .
Is this color from
~ recent volcanic activity (30+ active currently)
~ radioactive isotopes (Fukashima plus all the others that leak 24/7/365 but go unreported)
~ chemtrails

Obviously this color is not normal.
Do any of you actively collect rain water?
Do you monitor the quality?
Are you seeing anything similar?
