Identification of the hydrogeochemical processes and assessment of groundwater quality, using multivariate statistical approaches and water quality index in a wastewater irrigated region
(MDPI, 2019)"Groundwater quality and availability are essential for human consumption and social and economic activities in arid and semiarid regions. Many developing countries use wastewater for irrigation, which has in most cases ... -
Occurrence of anticyclonic tornadoes in a topographically complex region of Mexico
(Hindawi Publishing Corporation, 2019)"Tornadoes are violent and destructive natural phenomena that occur on a local scale in most regions around the world. Severe storms occasionally lead to the formation of mesocyclones, whose direction or sense of rotation ... -
Constraining a density-dependent flow model with the transient electromagnetic method in a coastal aquifer in Mexico to assess seawater intrusion
(Springer, 2019)"Saltwater intrusion is one of the most pressing environmental concerns in coastal areas with increased water demands. Water extraction decreases the level of fresh groundwater, reducing the water pressure and allowing ... -
Optimizing the differential pulse anodic stripping voltammetry method with hanging mercury electrode for thallium (I) determination in the presence of lead (II) and copper (II) for application in contaminated soils
(Universidad Nacional Autónoma de México, Universidad Autónoma de Tlaxcala, Universidad Veracruzana, Universidad Autónoma de Occidente, Centro de Ciencias de la Atmósfera, 2019)"The conditions that allow thallium (I) determination in the presence of lead (II) and copper (II) were optimized without prior separation of these cations, using a previously developed differential pulse anodic stripping ... -
Geology of the late Pliocene - Pleistocene Acoculco caldera complex, eastern Trans-Mexican Volcanic Belt (México)
(Taylor & Francis LTD, 2019)"We present a new 1:80,000-scale geologic map of the Acoculco caldera (Ac) located between the states of Puebla and Hidalgo in eastern Mexico. The map, encompassing an area of 856 km(2), is grounded on an ArcMap data set ... -
Water poverty index in arid zones: the barril aquifer, Santo Domingo, San Luis Potosí, México
(Universidad Nacional Autónoma de México, Universidad Autónoma de Tlaxcala, Universidad Veracruzana, Universidad Autónoma de Occidente, Centro de Ciencias de la Atmósfera, 2019)"In Mexico, 73.7 % of the territory is made up of arid and semi-arid zones where groundwater is the main source of supply for the population's various activities. The municipality of Santo Domingo is in such a case, with ... -
Geology of the late Pleistocene Tres Vírgenes Volcanic Complex, Baja California Sur (México)
(Taylor & Francis LTD, 2019)"The geological map of the Tres Vírgenes Volcanic Complex (TVVC) Baja California Sur, México consists of three northeast-southwest aligned stratovolcanoes named from older to younger, El Viejo, El Azufre, and La Virgen. ... -
Role of unsaturated soil above a heavily contaminated aquifer in the natural attenuation of arsenic
(EDP Sciences, 2019)"Large attenuation of arsenic is observed in a shallow aquifer in central Mexico, where the concentration decreases from 91.5 to 11.3 mg/L, over 1.3 km horizontal distance. To investigate possible mechanisms of attenuation ... -
