new state institution, the Thermes Chevalley were inaugurated, relying on several new deep catchment sources. The underground travel of the waters, from the opposite shore of the lake (more than thirty years at deep), explains its temperature of 46°. Many sources provide calcium, sulphated, silica-rich waters which are very slightly radioactive at 45° or cold, and finally with bicarbonatees. They, according to their origin and their temperature, are used either for showers or baths, in a swimming-pool, or to drink. These warm waters are especially indicated for degenerative rheumatism such as lumbar or cervical arthritis, osteoarthritis, sciatica, acute lumbago, recurrent arthritis of the hands, knee osteoarthritis, and for inflammatory rheumatism and spontylarthrite rheumatism. The use of sources is also beneficial for the algodystrophy, tendonitis, and phlebological problems (chronic venous insufficiency, suites and sequelae of thrombosis, lymphatic insufficiency, Raynaud's disease), on the other hand, these waters are contraindicated for the varicose ulcer, stroke or recent cardiac events. The cure techniques are the use of showers, individual enclosure (Berthollet), physiotherapy, mud application, underwater showers, and rehabilitation in a swimming pool. By their calming of the nervous system, the waters can cause euphoric relaxation. The national baths of Aix-les-Bains consist of two buildings located on two very distinct sites. Thus the Thermes Pellegrini and the Thermes Chevalley Spa facilities are located on the height. There is also the Marlioz Spa. This is located in a park of . It uses water from springs discovered around 1850. A first private institution was built in 1860, then entirely rebuilt in 1980. This spa is particularly suitable for the release of the respiratory system and heals diseases of the mouth. Treated ENT diseases are otitis, rhinitis, sinusitis, the pharyngitis, tonsillitis, the laryngitis, surgical preparations and post-surgical in ENT. Also treated are pathologies in pneumology, tracheitis, bronchitis, bronchial dilation and finally asthma. Thanks to its thermal baths, in 1986, the town had around 52,000 hydrotherapy visitors and 1992, more than 44,550 hydrotherapy visitors. Since the year 2000, as a result of the disappearance of the agreements with the social security, attendance has decreased. Aix-les-Bains hosted approximately 35,200 hydrotherapy visitors for the year 2005. This number represents about 7% of all spa guests in France and 60% of the Savoy hydrotherapy visitors. Between the year 2004 and 2005, a significant decrease of 3% in the rate of attendance was found. March 2008 began with a serious conflict between
