The article on the Brexit concern on water treatment chemicals does not make much sense. They are bulk chemicals readily available on the world market. Most are probably produced in China. The article on the Swedish Water  concern about silver seems overblown. Is the full report available?  Silver is not very  toxic although it does have some bacteriostatic properties. It was once integral to the  photographic film process , but that use is essentially ahistorical curiosity with the advent of digital photography and video tape. It also readily precipitates with chloride and some other common anions in the environment and in sewage so it should be fairly easily  removed to the sludge  in a sewage plant. A role in antibiotic resistance production under environmental conditions also seems to be unlikely.
