“…in contact with the basement, our results provide the first description of the structural flow model of hot water from the basement into the surface [13,14]. The faults allowed the hot water to rise to the surface where they combined with the cold water to form thermal water springs in various locations [20]. Further, the flow circuit shows that the decrease in source temperatures and depth values are interchangeably related, supporting the following two [12,19].…”

Thermal water in northeastern Algeria (Setif) is a promising, sustainable resource of energy. To date, thermal water has not been used as a source of renewable energy in Algeria as no clear strategy has yet been developed for its use. In this study, eight samples of thermal water springs distributed within the area of Setif city were assessed, and their physical and chemical parameters (such as temperature, potential of hydrogen, electrical conductivity, and major ionic composition, including the K+, Na+, Ca2+, Mg2+, Cl−, SO42− and HCO3−) were measured. The results show that the temperature, potential of hydrogen and the electrical conductivity range between 30 and 52 °C (as measured in field), 6.92 and 7.35, and 1170 and 3160 µS/cm, respectively. Furthermore, the results indicate the existence of four hydrogeochemical facies dominating the hydrogeological system, which are SO4–Ca, Na–SO4, HCO3–Na and Cl–Na. The interaction with Jurassic limestone and the existence of evaporates along the upwelling system, respectively, control this. Due to the high variation of temperature, different geothermometers were used to estimate the geothermal reservoir temperature, the application of silica geothermometer (Quartz), because it is the most suitable in our case, gives temperatures estimated at the origin of the order of 80° C. It is higher than that measured at emergence, it reflects an average dissipation of 48° C. According to an analysis of these findings and the geothermal gradient in the area, two aquifer systems of the thermal complex are supplied by a reservoir that is stored in fissured Jurassic limestone that is more than 2600 m deep.

Free-living amoeba (FLA) such as Acanthamoeba , Naegleria , Balamuthia, and Vermamoeba have been identified from both natural and human-made environments such as Hot springs and spa. Naegleria fowleri causes Primary Amoebic Meningoencephalitis (PAM), while Acanthamoeba and Balamuthia cause chronic granulomatous encephalitis. Acanthamoeba also can cause cutaneous lesions and Amoebic Keratitis (AK) that is associated with contact lens use or corneal trauma. FLA are known to serve as host of and vehicles for diverse intracellular organisms. This study aimed was to identify the presence of FLA in the hot springs and beaches of the Caspian Sea in Ramsar tourist town located in the northern part of Iran. Water samples were collected in sterile bottles and were transferred to the laboratory. One litre of each sample passed through the nitrocellulose membrane filter. Each filter insert was then placed in non-nutrient agar plates already seeded with lawn culture of Escherichia coli . Positive samples were analyzed by morphological keys and Polymerase chain reaction (PCR) using 18S rDNA gene and ITS region to identify amoeba isolates. A total of 81 water sampled were tasted. After identified using the morphological key and PCR assay, 54 (66.6%) of the samples were positive for FLA. Ten of the samples were identified as Acanthamoeba (belong to T3, T4, and T5 genotypes), three as Vermamoeba vermiformis , four as Naegleria (3 N.australiensis and 1 N.grubery ). Only one sample was positive Vahlkampfia . The presence of thermotolerant FLA in the Hot springs and beaches of the Caspian Sea as places for recreational purposes or wellness may be a potential health risk.
