“…Improving this problem would enable valuable data management and storage for the geometric modelling of the coastal aquifer applied in other studies [68,69]. These data allow estimating the distribution of hydraulic conductivity, controlling the invasion of saline intrusion that affects these systems and establishing strategies to conserve them.…”

The scientific community has a growing interest in understanding the interaction of the human-water system in water resource models. In Santa Elena (Ecuador), Valdivia, San Pedro, Sinchal, Barcelona and Carrizal communities are located in a semi-arid area, making the water supply a critical problem for local communities. In addition to the climatic conditions of the sector, the main problem is the weak participation in the integral management of the groundwater resource by the stakeholders involved. Specifically, there is evidence of a lack of ancestral-technical knowledge in management strategies and the fact that the demand for water for agriculture, tourism, and their basic needs exceed the sustainable supply capacity. The present study assesses the natural and anthropic conditions of the middle and lower basin of the Valdivia river through a socio-hydrogeological conceptual model of the river-aquifer system to develop productive activities in an environment of sustainability. The study methodology consists of four phases: i) river basin data analysis, ii) hydrogeological studies, iii) application of the Participatory Action Research (PAR) and Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis, and iv) conceptual model of the river-aquifer system. The results show that the socio-hydrogeological model of the Valdivia River basin has four systems: hydrogeological, ecological, economic, and social. In addition, the research detected problems present in the systems, such as droughts due to the influence of natural phenomena, aquifer overexploitation, lack of aquifer sustainability techniques, weak management and control of water resources, contamination of water sources and a lack of support from government agencies. The systems identified allow JAAPR-Valdivia to manage strategies to solve the problems detected in search of the sustainability of water resources.

“…The geology of the area comprises sedimentary rocks, volcanic rocks of basic composition and alluvial deposits made up of gravel and sand, which make up the aquifers of the sector [95]. In the geological-mining aspect, two essential resources stand out: (i) zeolite, which has beneficial surface and structural properties applied in agriculture and the environment [96], and (ii) the Manglaralto River aquifer, the primary water source [97,98]. Among the applications in the environment of zeolite is the use of zeolite to neutralize a heavy metal (Nickel) in a soil environment [99].…”

“…With the application of the GeoModeller software in previous studies, three-dimensional (3D) models were generated, which allowed estimating the volume of the aquifer capacity in the coastal aquifer of the Manglaralto River [97]. In this study, 3D models of the Cadeate River and Simón Bolívar River aquifers were generated.…”

Georesources comprise spaces of relevant geological value with the potential to be used and managed as a resource. Therefore, georesources are an essential development factor in the world, mainly oriented to their rational use to improve the quality of life of the surrounding population. This work aims to analyze the main applications, conservation strategies and sustainable use of georesources in the rural area of Manglaralto (Ecuador) through their inventory, assessment and analysis for the adaptation of alternative uses to particular circumstances (e.g., the COVID-19 pandemic). The method used consists of four phases: (i) inventory and mapping of georesources; (ii) description and assessment of georesources using international methodologies (e.g., GtRAM for georoute assessment, hydrogeological characterization using GeoModeller for groundwater assessment, GIS tools for assessing materials with industrial–artisanal interest, and KFM matrix method for the assessment of the level of construction difficulty of sanitary landfills); (iii) georesources complementary applications and (iv) SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) and TOWS matrix preparation (Threats, Opportunities, Weaknesses, Strengths), seeking strategies to guarantee the viability of the use of georesources. As a main result of the investigation, the geolocation of the georesources of the area was obtained. In addition, the assessment of the main georesources such as (i) potential geosites and sites of geological interest (e.g., beaches, cliffs, waterfalls, capes), (ii) groundwater (aquifers), and (iii) materials with artisanal and industrial interest (e.g., clays, sands). Finally, the study allowed us to define areas to develop landfill infrastructure, identify ecosystem services, and construct tsunami refuge site proposals. The case study addressed shows that the inventory and definition of the use of geological resources constitute a fundamental process for the economic, social, and environmental development of the population.

Hydrogeology in the Andes cordillera reflects its complex geological history. In most cases, groundwater flows through fractures and faults that compartmentalize the volcanic material, and through the primary porosity of the volcano-sedimentary material. The volcanic mineral context and geothermal environment mark the groundwater chemistry, especially in the high concentrations of specific trace elements. This study focuses on the complex system of the Tumbaco – Cumbayá – Los Chillos aquifer, in the vicinity of the Ilaló volcano near Quito (Ecuador). Hydrodynamic, geochemical and isotopic tools were used to assess the chemical characteristics of water and its origin, identify the recharge areas, and estimate the transit time of water using simple methods and scarce data. Results revealed two distinct aquifers, one in the volcanic cone located in the center of the study area, and the other in the volcano-sedimentary series of the Tumbaco – Cumbayá – Los Chillos valley. The volcanic aquifer is characterized by a high mineralization, a recharge zone between 2400 m asl and 3100 m asl, and radiocarbon concentrations lower than 20 pmc. The volcano-sedimentary aquifer seems to behave as a partly disconnected system, between the north and the south of Ilaló volcano, and also with a great heterogeneity, maybe due to the presence of lenses of volcanic ash. It has an intermediate mineralization, a mean recharge zone between 2,300 and 2,700 m asl, and 14C activities between 45.4 and 87.4 pmc in apparent contradiction with the hydrodynamic mass balance.
