As long as you don't enter any data into this site, you're okay.

Can you elaborate why?

Due to the fact that the website has no revenue stream, and it's obvious someone put a decent chunk of money out to build it, I suspect that it's run by someone, like Nestle, which has plans to control all potable water.

Pretty sure this guy funded it…

How sure are you that he's acting alone?

Not sure really. But I can see the angle you’re coming from. That there are many more private springs that haven’t participated in the initiative is a good thing too.

I saw people in England discussing this site, which is when I first saw mention of it. People were questioning, "Why would I want tourists ruining my favorite spot?" I started to wonder what strong desire inspired the creation and execution of the site. It doesn't seem to be a revenue generator, and could be used to poison local water sources, even unintentionally. A better way to learn where to find water is to go hiking.

I think the answer is somewhere in between. There are some people who own springs who clearly just want to share with others the magic of wild water. The most basic of resources after clean air. There will be others who are more cautious.
