Caracterització quimicomineral de l’aigua de les fonts del Montseny selvatà
Between November 2018 and January 2019, we analysed mineralogical water from seventy-five springs of Montseny (La Selva region, Catalonia) using techniques of analysis ofpotentiometry, conductimetry, acid-base volumetry, Mohr volumetry, turbidimetry, UV spectrophotometry, complexometric and flame ph...

| Sumario: | Between November 2018 and January 2019, we analysed mineralogical water from seventy-five springs of Montseny (La Selva region, Catalonia) using techniques of analysis ofpotentiometry, conductimetry, acid-base volumetry, Mohr volumetry, turbidimetry, UV spectrophotometry, complexometric and flame photometry. The statistical analysis of the data obtained shows that the Montseny (La Selva region) global mineralization of water from the sources is low, although there are particular cases due to specific circumstances, usually related to local anthropic or lithological issues. In the study area it has been found that the altitude of the source is a fairly reliable indicator of the degree of mineralization. The major ions are bicarbonate and calcium and, to a small quantity, sodium. Regarding nitrate pollution, it is shown that the water is of high quality, since only 4% of the sources analysed exceed the 50 mg/l established in the RD 140/2003 as limit for drinking water. |
