I’ve dropped a line to the Surfers against Sewage campaign page where they offer help for getting your site listed as a bathing site (https://protectingwildwaters.org.uk/)
I did this in order to ask the question about how we go about recording bathers over the swimming season if the waters are too foul and a health risk to get into! Knowing what we know about our river, how can we ask any of our community to regularly get into those waters and risk their health in order for it to be logged as a bathing site? Anywho – I’ve asked them who it is we might speak to at the regulating bodies about this. Figured it’s a place to start!
