La qualità dell'acqua è ottima in quasi tutti i lidi svizzeri: a dirlo è l’ultimo rapporto sulle acque di balneazione dell’Agenzia europea dell’ambiente (AEA), pubblicato venerdì a Copenaghen.
Stando al rapporto, l'82,5% degli specchi d'acqua analizzati in Svizzera nel 2021 presentava condizioni idriche eccellenti. Solo il 2,1% dei 189 siti di balneazione presi in considerazione è stato classificato come scarso a causa della presenza di batteri nocivi.
Per la valutazione, l'autorità ha esaminato il carico di batteri fecali nelle acque, in particolare enterococchi intestinali ed Escherichia coli, che provengono principalmente dalle acque reflue e dall'agricoltura. Questi possono causare malattie nell'uomo.
Secondo il rapporto, la percentuale di acque di balneazione di scarsa qualità è in diminuzione dal 2013. Nel 2021 quelle scadenti rappresentavano solo l'1,5% di tutte le acque di balneazione dell'UE, in calo rispetto al 2% del 2013.
La Svizzera non figura tra i paesi con la maggiore quota acque balneabili di qualità eccellente
