“…Central Mexico is an area where water quality has been given much attention in recent years because of the high As and F concentrations in groundwater [30][31][32]. Due to the predominant semiarid climate and abundance of endorheic basins in Central Mexico, salinization of groundwater is a major concern [24,[33][34][35]. Recent local studies of salinization of groundwater include a wellfield in Nuevo Leon [36] and the Calera aquifer in Zacatecas [37].…”

“…Normal faults during Cenozoic extensional episodes formed horsts and graben structures [38]. Through time, erosion filled the grabens (basins) with rock fragments, secondary minerals, among which iron oxyhydroxides were a common component, and clays [32,33]. About half of the basins are endorheic and the rest discharge to the Pacific Ocean.…”

Groundwater salinization is a major threat to the water supply in coastal and arid areas, a threat that is expected to worsen by increased groundwater withdrawals and by global warming. Groundwater quality in Central Mexico may be at risk of salinization due to its arid climate and since groundwater is the primary source for drinking and agriculture water. Only a handful of studies on groundwater salinization have been reported for this region, most constrained to a small area and without trend analyses. To determine the extent of salinization, total dissolved solids (TDS), sodium (Na+), nitrate as nitrogen (NO3-N) and sodium adsorption ratio (SAR) are commonly used. Available water quality data for about 200 wells, sampled annually between 2012 and 2021, were used to map the spatial distribution of NO3-N, TDS, Na+, and SAR. Upward trends and Spearman correlation were also determined. The study area was subdivided into three sections to estimate the impact of climate and lithologies on groundwater salinity. The results showed that human activities (agriculture) and dissolution of carbonate and evaporite rocks were major sources of salinity, and evaporation an enriching factor. Temporal trends occurred in only a few (about 7%) wells, primarily in NO3-N. The water quality for irrigation was generally good, (SAR < 10 in 95% of samples); however, eight wells contained water hazardous to soil (TDS > 1750 mg L−1 and SAR > 9). The results detected one aquifer with consistently high concentrations and upward trends and eight lesser impacted aquifers. Identifying the wells with upward trends is important in narrowing down the possible causes of their concentration increase with time and to develop strategies that will infuse sustainability to groundwater management.

“…Salinity sources could be natural, anthropogenic, or both together. When it comes to anthropogenic sources of salinity those can be irrigation with saline water and poor soil management, or soil pollution due to the excessive use of fertilizers (Lopez-Alvarez et al, 2021).…”

Soil salinity is a problem that affects many countries, and one of them is the United Arab Emirates. A microorganism that has been known for its salinity resistance mechanisms could be a factor in improving and enhancing agricultural problems. The aim of this study is to explore the use of Bacillus Subtilis in agricultural practices and how it can affect growth under saline conditions and guide future studies in this field with the goal of giving better implications and providing more information. Bacillus Subtilis was introduced to a plant that cannot tolerate high salinity levels, Phaseolus Vulgaris. Three different methods were used in conducting this study: (1) germination of seeds in bacterial broth, (2) inoculation of seeds with bacterial broth, and (3) spreading of bacterial broth on soil samples. This study confirmed that using Bacillus Subtilis with Phaseolus Vulgaris indeed increases its resistance in saline conditions. Moreover, using this bacterium could be the solution to agricultural problems due to high salinity levels if they were engineered and modified to enhance their resistance tolerance. The recommendations to this study would be to implement it in a controlled field and explore the usage of Bacillus Subtilis with different plants and soils as well as to check how other factors, such as temperature, affect the growth of plants in saline conditions while Bacillus Subtilis is present in that environment. Another recommendation would be collecting data with different methods and using DNA sequencing to check how Bacillus Subtilis affect soils and the microbes that exist in those soils.
