In the present work, the concentration of fluorides in deep wells that supply drinking water to an average city of approximately 110,000 inhabitants, located in the upper region of the state of Jalisco, was related with the dynamic level of extraction (depth), finding that of the 49 deep wells that the city regularly operates, 25 % have fluoride concentrations that exceed the maximum permissible limit for drinking water, reporting values of up to 11.44 mg / L. The highest concentrations of fluorides are located mainly in wells located to the West, Northwest and Southeast of the city center, some possible causes of the high concentration of fluorides can be: the number of wells operating, the high extraction volumes and the hours that operate daily, consequently dynamic levels of average extraction are observed in the study area of 185 meters.

Mediante los postulados básicos del modelo de Gestión Local del Agua en Cuencas (GLAC,) en el presente trabajo se aborda la eventual participación de la iniciativa privada en la administración de los servicio de agua potable y saneamiento en el municipio de Tepatitlán en la región Altos de Jalisco, evidenciando avances, limitaciones y retos. Rescatando una mayor participación social y privada, así como más trasparencia en el manejo de recursos, promoviendo estrategias que mejoran los procesos que dan sustentabilidad al agua. Abstract: Analyzing the changes, in the last decades of the organizational schemes for the management of the water resources in our country, important modifications are detected mainly in the conformation of actors, norms, processes and spaces involved. The basic postulates of the Local Water Management at Basins (LWMB), in this paper addresses the possible participation of private initiative in the administration of drinking water and sanitation services in the municipality of Tepatitlán in the Highlands of Jalisco region, demonstrating advances, limitations and challenges. Rescuing greater social and private participation, as well as more transparency in the management of resources, promoting strategies that improve the processes that give sustainability to the wáter.

In the particular case that the river is an ecosystem of great richness and complexity, necessary for the sustainability of the population centres, a true urban planning must consider the adequate conservation of the natural causes of water (rivers and streams among others), avoiding using these routes as waste and wastewater collectors. Through the results obtained in the present monitoring it is possible to appreciate that the water quality in the main water bodies of the microbasin such as the Tepatitlan river decreases sensibly, from its origin in the Jihuite stream to the exit of the municipality of Tepatitlan, due to among other factors; the population growth, the increase in agricultural production in the study area, resulting in point and diffuse discharges of effluents without treatment, both of domestic origin as well as of agricultural and industrial farms, together with the limitations in the systems for the adequate treatment of domestic wastewater. It highlights a high organic pollution at the exit of the municipality evidenced mainly by: the low Concentrations of Oxygen Dissolved, high values of Specific Conductance, Chlorides, Oxygen Potential Reduction and ammonic Nitrogen that cause critical conditions for sustaining aquatic life, the use for agriculture, human and animal consumption, as well as problems of environmental pollution.

The agricultural activity in the region is of great relevance at the national level, which also generates high volumes of organic waste (solid and liquid), which in many cases are not handled properly causing serious environmental damage. This paper presents advances in the determination of the contamination of the surface waters of the 20 municipalities that make up the Jalisco Highlands region, making comparisons with available information for the years 2014 and 2016, physicochemical parameters such as: Dissolved Oxygen, Specific Conductivity, Salinity, Oxide-Reduction Potential, Ammonia Nitrogen and Chemical Oxygen Demand. In general, a certain degree of contamination is perceived in most of the bodies of water studied, exposing evidence of the gradual contamination of dams and rivers, mainly due to the discharge of wastewater (domestic and industrial) without treatment, as well as by dragging of waste organic solid, mainly in the municipalities of: Lagos de Moreno, San Juan de los Lagos, Union de San Antonio, Villa Hidalgo, Acatic, Tepatitlan and Arandas, the municipalities that presented less pollution in their surface waters were Teocaltiche, Jesus Maria and San Ignacio Cerro Gordo.
