- Expert based DRASTIC adaptation to mineralized aquifer vulnerability assessment - Penamacor, PortugalPublication . Gomes, L. Ferreira; Albuquerque, M.T.D.; Antunes, I.M.H.R.Hydrotherapy and bottling mineral water exploitation requires a detailed placement of the catchment and the aquifer’s vulnerability assessment for further protection perimeter design. The DRASTIC methodology was the starting point index used for the herein introduced “specific DRASTIC”. It is possible to say that hydrogeologically the area suggests a predominant low vulnerability. However, hydrogeological and structural characteristics (e.g., granitic fracturation), indicate an extremely high vulnerability in which concerns to the Termas de Fonte Santa catchment. The "specific DRASTIC” index is held by local parameters in order to downscale the key properties for local vulnerability mapping and further quantification of the potential for contamination of the aquifer. The Termas de Fonte Santa is classified as very high to extremely high vulnerable and in need of protection and conservation.

- New thermal mineral water from Aguas (Penamacor, Central Portugal): hydrogeochemistry and therapeutic IndicationsPublication . Gomes, L. Ferreira; Antunes, I.M.H.R.; Albuquerque, M.T.D.; Silva, A. SantosThermal mineral waters are a potential resource in the local and economic development of a region. The thermal area of Termas das Águas is in the inner region of central Portugal and its grant will enable the exploration and exploitation of this water resource for medical and therapeutic purposes through a thermal medical SPA. In Portugal, the classification and legalization of a thermal unit must provide a natural mineral water resource, recognized by Portuguese Energy and Geology General Directorate and integrated in a concession granted by the Portuguese Government. For this purpose, it will be necessary to have available mineral water, with physico-chemical and microbiological, temporal stability, ensuring water’s high quality. The purpose of a certified mineral water includes a detailed geomorphological, geological and hydrogeological characterization of the survey area, as well as the water's compositional temporal stability. Only after the recognition conferred by the national agency as a natural mineral water, it is possible to start a medical-hydrological study, for this resource. This process follows an experimental period of 3 years, during which it is implemented the different and specific balneotherapy techniques associated with the therapeutic features of the mineral water. A final report, to be submitted to Portuguese General Directorate for Health, will gather the main results and conclusions, regarding the benefits of this natural resource on human health, and allow its inclusion as an official medical thermal SPA in the Portuguese Normative Decrees. The main subject of this research is the geological and hydrogeological characterization of Termas das Águas aquifer, as well as the mineral water quality study (AM4 – well). The main topics for the medical hydrological study, mainly related to rheumatic and respiratory diseases, are also presented to the medical SPA of Termas das Águas.
- Novel therapeutic indications – the mineral water of Termas de Águas Spa (Penamacor, Portugal)Publication . Gomes, L. Ferreira; Albuquerque, M.T.D.; Antunes, I.M.H.R.; Silva, A. SantosThermal mineral waters are a potential resource in the economic development of a region. The thermal Águas Spa is located in the inner region of central Portugal and its grant will enable the exploration and exploitation of this water resource for medical and therapeutic purposes through a thermal medical spa. The study area is located in the Central Iberian Zone, central Portugal, at the village of Águas, about 42 km NE of Castelo Branco and 5 km south of Penamacor. The main idea of this research is to establish the principal water characteristics that allowed its recognition, by the Portuguese Ministry of Health, for rheumatic and respiratory diseases treatment. Termas de Águas Spa has a current use groundwater catchment located in the granitic pluton of Penamacor-Monsanto, which intruded the schist-metagraywacke complex. Topically, there are dispersed alluvial materials from the Ribeira das Termas; the main river through the survey area. This thermal mineral water aquifer is located in a slightly altered granite, highly fractured, corresponding to a semi-coni ned – coni ned aquifer, with superi cial runof groundwater recharge. The groundwater catchment (AM4), about 328 m deep, holds an average l ow of 0.8 L/s. The main features of the mineralized water are: temperature of 19ºC, neutral pH (pH = 7.3), low mineralization (total mineralization = 244 mg/L), sulphurous (H2S = 0.31 mg/L), sodium and bicarbonate type (HCO3 - = 128 mg/L, Na = 56.4 mg/L), slightly l uoride (F- = 2.5 mg/L) and substantial amounts of silica (SiO2 = 35.8 mg/L), corresponding to 15% of the total mineralization. A physico-chemical comparison between the groundwater of the catchment AM4, and similar waters, corresponding to the main Portuguese thermal units, shows a lower pH (pH range = 8.3-9.5) and a lower l uoride content (global average of F = 9.9-24.0 mg/L). These features may introduce novel utilities concerning to hydrotherapy, particularly in the treatment of rheumatic and respiratory diseases.
