It’s probably helpful to remove some of the noise regarding that article. My understanding.
The government have permitted a temporary lifting of required standards, ie the use of Ferric Sulphate from the final stage of sewage treatment. This must be applied for under license and is on the provision that none of the above chemical is available due to supply issues, this scenario hasn’t actually occurred yet.
Ferric Sulphate acts as a coagulant to bind heavy metals and reduce smell and increase clarity in discharge, it also helps to reduce Phosphates.
In short it’s not good but I recon this temporary work around for a final stage treatment chemical pales into insignificance compared to the multiple failings already present, discharge of actual raw sewage, agricultural land run off and over abstraction that concentrate the soup etc. It’s bad news but I wonder what ranks higher in its real world impact, environmental or political. The head line bleeds that’s for sure.
