Sanctuaries devoted to Asclepius were established and operated for almost a thousand years in various Greek and Roman cities throughout the Mediterranean region. The Asclepieion sanctuary in Lentas (formerly known as Ancient Lebena) in Crete was famous for receiving water from a sacred spring. In Ancient Lebena, Levinaion was a famous centre for hydrotherapy, physiotherapy, and a psychiatric hospital. In the present paper, we aim to assess the hydrochemical status of this sacred spring that holds a prominent position in archaeological and historical studies. The main objectives of this study are: Initially, to present supervisory evidence (archaeological, geological, hydrochemical) of an area that was a water resource management model for many centuries, carrying out therapeutic work. The second objective is to present and compare hydrochemical data in the last century, i.e., from 1915 to 2021. The third objective is to highlight and warn of an incipient saltwater intrusion in the area along the Lentas coast. The fourth objective is to propose an alternative and sustainable form of water resources management in the region that requires the study and rational utilization of the sporadic small water springs in the region. Our study focuses on a basic hydrochemical analysis of spring and borehole water in the remains of Levinaion in the Lentas region, and their comparison with sparse historical data of the sacred spring water, aiming to interpret the impact of the changes in the spring water resources that occurred in recent decades due to urban modernization. Our results highlight (i) visible fluctuations in chemical composition of borehole water samples; (ii) a neutral to alkaline pH in borehole waters and an alkaline pH in spring waters; (iii) undetectable arsenic in Lentas borehole water, unlike historical data of Lentas spring water; (iv) low values of dissolved radon in Lentas borehole water and the spring water of Kefalovrysa; and (v) a timeless constant and hypothermic nature of the water of both the sacred spring and borehole of Lentas, and also of the Kefalovrysa spring. The recorded historical data, i.e., from 1915 to 1957, due to the absence of substantial anthropogenic activity in the area, can be used as reference values (natural background levels, NBLs) for the Lentas area. Our findings emerge with the need to bring again the flowing spring water of the sacred spring of Lentas in its original form through sustainable management and re-discover its beneficial therapeutical effects.

“…Sustainable management of groundwater resources has been paid attention to in many countries (Gu et al 2016b;Blake et al 2021;Stephens et al 2021;Arnaud et al 2022;Colyer et al 2022). In China, approximately 8 billion tons of groundwater is being ruined by coal mining every year, but the utilization rate is only approximately 25% (Xie and Wang 2014).…”

Coal pillar dams are an important component of the water storage bodies of underground reservoirs. Influenced by the overlying rock pressure and water seepage, the stability of the coal pillar dam is one of the key factors affecting the stability of underground reservoirs. In this paper, an anisotropic seepage mechanical model of a coal pillar dam under plane strain was established to study the seepage stress coupling mechanism of underground reservoir No. 4 in the Daliuta Coal Mine using the COMSOL Multiphysics code. The stress field and seepage field of the coal pillar dam body were analyzed, and the influence of the principal direction of the mechanical properties of the coal pillar on the stress field, seepage field, and damaged areas of the coal pillar and goaf were discussed. According to the results, the anisotropy of the coal pillar dam body is one of the most significant factors when the principal direction of mechanical properties is θ = 45° or θ = 135°. The coal pillar damage area reaches a maximum value accounting for nearly 50%. The shear stress of the coal pillar reaches 4.69 MPa, which attains the maximum value when the principal direction angle is 90°. With increasing depth, the damaged area of the coal pillar gradually expands in the scenario of θ = 0°. When the depth increases to 160 m, the coal pillar undergoes penetration failure. In conclusion, the principal direction is the main factor affecting the stress field, seepage field displacement field, and energy evolution of the model. The anisotropy model of the equivalent continuum can account for the influence of the coal pillar structure surface, which could provide an analytical model for the stability of rock engineering.
