In recent years, groundwater is becoming increasingly important as a result of the continuous population growth and the consequent increase in drinking water.

Negli ultimi anni, le risorse idriche sotterranee stanno acquisendo sempre più importanza a seguito della continua crescita demografica e quindi dell’aumento della richiesta di acqua potabile. In questo contesto, le Alpi Apuane risultano di particolare interesse grazie alla presenza di ingenti risorse idriche ospitate in acquiferi carsici e caratterizzate da una buona qualità. Molte sorgenti che scaturiscono nell’area apuana vengono da tempo captate per uso idropotabile, tuttavia la loro tutela è messa fortemente a rischio anche dalla presenza di numerose attività antropiche impattanti, quali le aree estrattive, nonché dai cambiamenti climatici in atto. Per una corretta gestione e salvaguardia di tale preziosa risorsa è necessario disporre di elevate conoscenze del sistema ambiente che possono essere raggiunte solo attraverso studi integrati multidisciplinari. Questo articolo vuole offrire una breve panoramica delle conoscenze attuali acquisite mediante l’utilizzo di metodologie geologiche, idrogeologiche e geochimiche isotopiche. Gli studi effettuati hanno permesso di ottenere già importanti risultati: individuare i diversi sistemi acquiferi che alimentano le principali sorgenti delle Alpi Apuane; Comprendere le condizioni idrodinamiche degli acquiferi e di conseguenza le loro condizioni di vulnerabilità sia all’inquinamento che ai cambiamenti climatici; individuare le aree di alimentazione delle principali sorgenti con il fine di definirne le zone di protezione. I cambiamenti climatici attesi, fra i quali l’aumento della frequenza ed intensità degli eventi estremi, avrà inevitabilmente conseguenze anche sull’area apuana e sulle sue risorse, con impatto sull’incremento del dissesto idrogeologico e sulla potenziale diminuzione delle risorse idriche. Ciò rende sempre più indifferibile l’aumento della conoscenza sul territorio, sulle sue risorse e sulle sue esigenze, e in secondo luogo una presa di coscienza definitiva da parte della popolazione e soprattutto degli enti che ne sono preposti alla gestione.

Abstract
In recent years, groundwater is becoming increasingly important as a result of the continuous population growth and the consequent increase in drinking water. In this context, the Apuan Alps are of particular interest thanks to the presence of large, good quality water resources hosted in karst aquifers. Many springs in the Apuan area have long been captured for drinking water use, but their protection is also strongly jeopardised by the presence of numerous anthropogenic activities, such as mining, as well as climate change. In order to correctly manage and safeguard this precious resource, an in-depth knowledge of the environmental system is necessary, which can only be acquired through integrated multidisciplinary studies. This article aims to provide a brief overview of the current knowledge acquired by means of geological, hydrogeological and isotopic geochemical methodologies. The studies carried out have already obtained important results: identification of the different aquifer systems feeding the main springs of the Apuan Alps; an understanding of the hydrodynamic conditions of the aquifers and consequently their vulnerability to both pollution and climate change; identification of the feeding areas of the main springs with the aim of defining their protection zones. The expected climate changes, among which the increase in the frequency and intensity of extreme events, will inevitably have effects on the Apuan area and its resources too, with an impact on the increase in hydrogeological instability and potential decrease in water resources. This makes the increase in knowledge about the territory, its resources and its needs more and more urgent. In addition, it is necessary to raise awareness among the population and, above all, the authorities responsible for its management.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
