L’acqua prelevata da due pozzi di captazione di Vacallo recentemente ha registrato un forte aumento delle concentrazioni di cloro, secondo quanto rivelato dalle analisi. Al Pozzo Vecchio i valori hanno superato i limiti di legge ed è quindi stato escluso dalla rete dell’acquedotto comunale. Al Pozzo Nuovo si è invece arrivati vicini ai limiti.
I due pozzi si trovano sul terreno delle piscine comunali di Chiasso e dopo la vuotatura della piscina quadrata a fine luglio le concentrazioni sono calate drasticamente. Si sospetta quindi che la contaminazione abbia avuto origine da questa vasca, che resterà quindi fuori servizio fino alla fine della stagione.
In seguito tutte le piscine e i loro circuiti saranno controllati ed eventuali problemi eliminati definitivamente.
