Thanks for this post. I live in rural Wales and have a spring I share with my neighbours.
All been OK with a simple paper filter fitted just to the kitchen drinking water tap. No need to filter all the water we use in my opinion.
I have recently however had a tummy bug and it could be the water. Although on inspection the tank seems fine. We have seen frogs swimming in there... but like you say ... if its clean enough for the creatures then it should be good to drink.
Anyway I didnt know about the wormwood and walnut tincture so I will give that a go....along with testing the water every now and then for bacteria etc.
I love the fact the earth gives us this gift of fresh flowing water. ✨️
