Spring Water Sample of the Upper Reaches

Help [110026|Gudisen] of Qilana Camp by going to [ZONE_ARGENFALL|Silverfall] and collecting a spring water sample with [201988|Collection Bottle # 4] from near the great waterfall.

Adventurer, do you know about the great waterfall below [ZONE_ARGENFALL|Silverfall]? Walk south along the spring and you will come to it.

I need some water from below the waterfall for my investigation. Can you help me? This sample is very important. Please make sure that you collect the sample using this collection bottle.

Oh yes. Don't think it is the small waterfall nearby. Actually there is a larger waterfall further south. That one is the one I am talking about.

Thank you. Now I can go on with my research.

The water of the large waterfall should be the purest. If it is polluted too... well, then the residents of Silverfall are in trouble.
