Free: Contests & Raffles.
Bring crystal light or Mio to make it taste a bit better once it's filtered at least.
You'll never get that taste out of it...trust me. Then your filter is nasty too.
Crapping water ? We always called it Pissing out your a--. Been there, and it's not fun. Will totally ruin you and your week's worth of undie's and any scent control is out the window. My Grand father always said, If you see this plant in the water, It will be safe to drink. Never trust your grand father. Remember, It was him that told you to pull his finger
Just pick up an inexpensive filter and pre-filter with some type of strainer or coffee filters. The Sawyer or newer Katadyn Be Free work awesome and cheaper than a tank of gas.
