OBJECTIVE: To perform a chemical analysis of all the available waters in Spain with the idea of offering consume recommendations to lithiasic patients. MATERIAL AND METHODS: Information research of the chemical composition of Spanish tap and bottled water in publications, supermarkets and Internet. A descriptive study, and a correlation study between water components by means of Pearson test were performed. RESULTS: Information about composition from tap water of most of the main Spanish cities and 85 bottled water brands was found. A significant correlation between calcium and magnesium concentration (p = 0.0001) and high correlation between bicarbonate and sodium concentration (p = 0.0001, Pearson coefficient 0.958) was found. It is also offered water classifications according to calcium, bicarbonate, sodium and magnesium concentrations. CONCLUSION: A guideline about water election for lithiasic patients is offered according to their geographical origin and dietetic preferences, mainly lactic consume.
