Can I thank the Member for his question and for his earlier correspondence again on this important issue? In terms of tackling this, and making sure we reduce and prevent the impact of any pollution of any kind or any instance within our river basins across Wales, wherever that may be, it's important that we work in partnership with stakeholders, with Welsh Water and Hafren Dyfrdwy and with Natural Resources Wales. And this, of course, is something that I'm happy to monitor very closely, going forward, to ensure that we get the outcomes that we need.
