When our water is brown usually the plumbing is the reason - there's rust in the water pipes because of old metal pipes.
I have never seen water which was brown because of the water itself. I mean, we have too much chalk in the water, but so much iron that the water is brown? No way.
But the Netherlands are different - that's what I have learned from you @wakeupkitty 😉
Have a nice day 🙂
When my autocorrection on the smartphone corrects something wrong I correct it again ;)
