No mention about Xylem in APAC but they have large amount of business in Europe and America
This is one I selected for my assessment over another one called Aris Water (they don't do PFAS, just clean up wastewater).
We can only select US listed stocks but I think it's a big benefit finding out there are these larger companies also competing for market share. Because then you also know how "small" your company is :)
I'm tempted to put more money into my US trading account.
