Le acque minerali nella zona del Monte Echia (Napoli)

In the past, at the south foot of the hill of “Monte Echia” (Napoli), where is located the Royal Continental Hotel, between Via Partenope and Via Chiatamone, gushed out sulphide- ferruginous springs. These water were used for drinking and bathing for many years, until they was interdicted for the cholera epidemic in 1973. Groundwater very similar in chemistry gushed out also in correspondence of “Vico Belledonne a Chiaia”. Over the years, many wells have been drilled for different purposes in the area of “Monte Echia” or nearby intercepting mineralized waters similar to the above mentioned waters, but totally different from the groundwater flowing below the rest of the city of Napoli. In this paper all the published data about these mineralized waters have been collected and the chemical features have been examined with the aim to individuate the process of the origin of the mineralization.
