LA SALITRERA, San Luis Potosí – Backhoes rapidly break down what decades ago was a pine and oak forest. Traca-tatatata-traca-tatatata. The mechanical rattling disrupts the silence of northern Mexico’s Sierra de Álvarez, one of 40 Flora and Fauna Protection Areas (APFF) in Mexico, just a few miles away from the world’s largest fluorspar mine.

Evaluation of Groundwater Quality for Human Consumption and Irrigation in Relation to Arsenic Concentration in Flow Systems in a Semi-Arid Mexican Region
Abstract The supply of drinking water to the population is an important challenge facing humanity, since both surface and underground sources present a great variability of water storage with respect to space and time. This problem is further aggravated in arid and semi-arid areas where rainfall is low and torrential, which makes groundwater the main […]
NMSU student receives fellowship to develop filter that removes arsenic and fluoride from the water in Palomas, Mexico
Community Snapshot: Joshua Gomez, who earned his bachelor’s in chemical engineering from New Mexico State University, has earned a fellowship from the National GEM Consortium, tuition for his master’s degree, a stipend for other expenses and two summers of experience conducting research at a national laboratory. As a freshman, Gomez received Environmental Protection Agency funding through NMSU’s Water […]
Co-occurrence, possible origin, and health-risk assessment of arsenic and fluoride in drinking water sources in Mexico: Geographical data visualization.
Highlights A groundwater arsenic-fluoride concentration map highlights enrichment zones. Volcanic glass is likely a primary source of arsenic-fluoride contaminated water. Evaporation in (semi)arid areas concentrates arsenic-fluoride in aquifers The states of Durango, San Luis Potosí, and Zacatecas have higher exposure risk Arsenic and fluoride in drinking water present a significant challenge to public health worldwide. […]

San José Iturbide: Warning issued over contaminated aquifer
The National Autonomous University of Mexico (UNAM) has issued an aquifer contamination warning for the Guanajuato municipality of San José Iturbide given high levels of radioactivity detected in at least 2,500 wells. UNAM researcher Marcos Adrían Ortega told the newspaper Milenio that at least half of those wells supply water for farming, and that five people […]
Prosperous Mexican Farms Suck Up Water, Leaving Villages High and Dry
SAN ANTONIO DE LOURDES, Mexico — In the dappled shade of mesquite trees by the side of a pale yellow schoolhouse, the children finished a song and waited for the priest’s blessing. The Rev. Juan Carlos Zesati began with a gentle exhortation, citing Pope Francis. “Water is part of God’s creation,” he said as he […]
Radiation an issue for Guanajuato water
Study finds levels 300% over permitted standards in San José Iturbide A study carried out last October by the National Nuclear Research Institute (ININ) has confirmed the presence of alpha radiation at 300% above permissible levels in the water supply of the Guanajuato town of San José Iturbide. For geohydrology expert Joel Carrillo the danger is not so […]
Pollutants up 2x in municipal water
Concentrations of arsenic and fluoride have doubled in the Lerma-Chapala aquifer As if drought conditions in many parts of Mexico weren’t enough, the levels of pollutants found in tap water are reaching worrisome levels, according to the results of a study by the National Autonomous University of Mexico (UNAM). The Geosciences Center (CGeo) at UNAM has […]
Guanajuato: Face Time with John Laskowski
John Laskowski is DeKalb’s City Engineer. He recently went on a trip to San Miguel de Allende in Guanajuato, Mexico, to use his engineering expertise to help people in rural communities create a water filtration system as a part of the Northern Illinois University Chapter of the Engineers Without Borders Program… Laskowski: Leading up to […]
