    A hydrogeological study of the thermal source of Ouled Aïcha in the Aurès Mountains showed that the source emerges in a particular natural context mainly represented by the presence of a vertical fault in the NE-SW direction affecting Cretaceous limestone. This supports the increase on the surface of moderately hot water, whose temperature is approximately 30 °C and an exploited flow of 3 L·s-1. The vertical electric sounding in situ showed the in-depth presence of a saliferous conducting level within a calcareous-resistant mass, which probably settled in the fault's favor. The presence of this saliferous level strongly influences the hydrochemistry of this thermal source. Thus, the water from the source is characterized by high salinity due to its temperature, which favors the dissolution of mineral salts in sufficient quantity throughout its journey (12390 µS/cm). The high concentrations of chlorides, sodium and sulfates indicate a significant contribution of salt from evaporitic formations as for the calcium content indicates that this water is influenced by the dissolution of carbonate formations. These physicochemical characteristics provide this water therapeutic virtue, which can be attributed to its chemical composition, high rock salt content, and low nitrate content. Geothermometry has shown that these thermal waters acquire a high temperature in their original tanks coming from a depth through a fault system that affects the basement.

    This study aims to evaluate the quality of wastewater treated by Mila's activated sludge process, assessing its potential for agricultural reuse. Effective wastewater treatment is essential to mitigate health risks associated with the use of surface and groundwater resources. Reusing treated wastewater for irrigation is a key objective, especially in arid and semiarid regions where water scarcity is prevalent. The research adheres to Algerian regulations, which currently restrict the reuse of urban effluent. We conducted comprehensive analyses of several critical parameters, including in situ measurements of temperature and pH using multi-parameter field probes. Laboratory analyses were performed to determine levels of suspended matter (SM), biochemical oxygen demand (BOD5), chemical oxygen demand (COD), nitrates (NO3), nitrites (NO2), ammonium (NH4), and total nitrogen (TN) using spectrophotometric and conventional techniques. To assess the irrigation suitability of the treated wastewater, we evaluated electrical conductivity (EC), sodium percentage (Na%), sodium absorption ratio (SAR), residual sodium carbonate (RSC), permeability index (PI), magnesium ratio (MR), and Kelley ratio (KR). Our findings, derived from field visits and observations of the purification processes, indicate that the treated effluents generally comply with quality standards for key pollutants, particularly BOD5, COD, and SM. The treated water meets the regulatory requirements for discharge into the receiving environment. Additionally, the evaluated parameters, including the average SAR value, which falls within acceptable limits, indicate that the treated wastewater is suitable for agricultural irrigation. Overall results showed no alkalinities, magnesium, or bicarbonate dangers associated with using Sidi Marouane WWPT's purified water for agriculture, indicating that the treated wastewater is suitable for agricultural irrigation.
