 Micro pollutants are from anti-baby pills, hormone-active substances, to dichlofenac, to pharmaceuticals, to pesticides. So there is a huge and a broad range of different kind of substances and they all do influence our water and our water qualities. So I think micro pollutants probably gonna be the next wave of investment into both technology and plants. And a lot of the time the regulation goes off to the big guys, which is the utilities. But utilities receive it at the Westward-Rugin plant in small quantities, but they get mixed into the very large quantity of water. So if you decide to treat and remove this micro pollutants at the level of utility, it's quite a significant investment you need to make. But instead, what you could do is a lot of the time pharmaceutical companies and hospitals, you can remove pollution before it hits the wastewater treatment plant. And that's where we see opportunities and technology companies coming in, not only trying to deliver the technology that helps to remove micro pollutants, they're actually trying to improve efficiency and improve the way the wastewater is processed today.
