“…Aunque el diagrama de Gibbs fue desarrollado originalmente para analizar los mecanismos que controlan la calidad del agua superficial (Gibbs, 1970), se le incluye en estudios de acuíferos de tipo libre, preferentemente en conjunto con otros indicadores (Su et al, 2021). Los diagramas de Gibbs y de cajas se realizaron en MS Excel.…”

“…Además, y debido a su asociación con residuos agrícolas, la presencia de NO3-N se utiliza como indicador de una amplia gama de contaminantes traza o emergentes tales como herbicidas, insecticidas, hormonas y antibióticos (Stuart & Lapworth, 2013;Gutiérrez et al, 2021b), los cuales pueden ser tóxicos a concentraciones muy bajas (Stuart & Lapworth, 2013). Estudios de As y F en agua subterránea concuerdan en que su origen es de tipo natural, iniciado con la interacción agua-roca (Kumar et al, 2020;McMahon et al, 2020;He et al, 2020;Su et al 2021;Alarcón-Herrera & Gutiérrez, 2022). Su contenido depende de las condiciones de redox, pH, alcalinidad, salinidad, y procesos de dilución, adsorción, y evaporación.…”

Se analizaron datos de calidad de agua subterránea de los estados de Chihuahua, Coahuila y Durango (N=704) para determinar la distribución de tres contaminantes comúnmente presentes en el área, arsénico (As), fluoruro (F), y nitrato (NO3-N), y determinar el efecto de factores de enriquecimiento. Dichos factores incluyen evaporación, intemperismo de rocas, HCO3, y solidos disueltos totales (SDT). Se construyeron mapas de concentración y se obtuvieron correlaciones para contaminantes entre sí, así como entre los contaminantes y factores de enriquecimiento. Los resultados muestran que los procesos más importantes de enriquecimiento de As y F son el intemperismo de rocas y en segundo lugar la evaporación, y para NO3-N el uso de suelo (agricultura) y la evaporación. La correlación entre As y F fue moderada (ρ= 0.417, p< 0.001) y no se encontró correlación entre As o F con NO3-N, SDT ni HCO3, lo que sugiere que la variación de tanto SDT como HCO3 dentro del área de estudio son insuficientes para afectar en forma significativa el contenido de As ó F. Asimismo, no se encontró una diferencia significativa entre el contenido de As ó F entre cuencas cerradas o cuencas abiertas. En contraste, NO3-N se encontró fuertemente asociado con SDT y ambos SDT y NO3-N concentrados en cuencas cerradas. Consecuencias indirectas de este estudio incluyen la identificación de 23 pozos con concentraciones extremas de As-F y la comparación de coberturas de datos entre los tres estados bajo estudio.

“…Fluoride (F − ) is an important mineral for humans, as it helps to enhance teeth and skeletal tissues [ 1 ]. However, fluorosis is a disease that destroys the teeth and bones and is caused by ingesting too much fluoride, which is widely found in drinking/groundwater (GW) [ 2 ]. Moderate doses have dental effects, but long-term ingestion can lead to serious bone disease [ 3 ].…”

Fluoride (F−) contamination in drinking groundwater is a significant human health risk in Pakistan. Moreover, high fluoride pollution in drinking water causes a variety of disorders, including dental, neurological, and skeletal fluorosis. The aim of this research was to evaluate the health risk of elevated fluoride in groundwater and its suitability assessment for drinking purposes. The total of (n = 37) samples were collected from community tube wells of Quetta Valley, Balochistan, Pakistan. The results show a mean pH value of 7.7, TDS of 404.6 mg/L, EC of 500 µs/cm, depth of 96.8 feet, and turbidity of 1.7 nephelometric turbidity units. The mean values of HCO3−, Ca2+, Mg2+, and Na+, were 289.5, 47.5, 30.6, and 283.3 mg/L, respectively. The mean values of SO42−, NO3−, K+, Cl−, and Fe2+, were 34.9, 1.0, 1.6, 25.6, and 0.01 mg/L, respectively. The F− concentration in the groundwater varied between 0.19 and 6.21, with a mean value of 1.8 mg/L, and 18 samples out of 37 were beyond the WHO recommended limit of 1.5 mg/L. The hydrochemical analysis results indicated that among the groundwater samples of the study area, 54% samples were Na-HCO3 type and 46% were mixed CaNaHCO3 type. The saturation indices of the mineral phases reveal that the groundwater sources of the study area were saturated with CaCO3 and halide minerals due to their positive (SI) values. Such minerals include calcite, dolomite, gypsum, and fluorite. The principal component analysis results reveal that the groundwater sources of the study area are contaminated due to geological and anthropogenic actions. The health risk assessment results of the F− concentrations show the ranges of ADDingestion for children, females, and males in the Quetta Valley, and their mean values were observed to be 0.093052, 0.068825, and 0.065071, respectively. The HQingestion mean values were 1.55086, 1.147089, and 1.084521 for children, females, and males, respectively. It was noticed that children had the highest maximum and average values of ADDingestion and HQingestion in the research area, indicating that groundwater fluoride intake poses the greatest health risk to children. The water quality index (WQI) analyses show that 44% of the samples belong to the poor-quality category, 49% were of good quality, and 8% of the samples of the study area belong to the excellent category.

“…A great many researchers have argued that phreatic groundwater could be threatened by contaminants from both geogenic and anthropogenic sources (Rajmohan and Prathapar, 2016;Ali et al, 2019;Reynolds and Johnson, 2019;Alqahtani et al, 2020). For example, Su et al (2021) studied the fluoride-enriched groundwater in the Tarim Basin, and found the unconfined aquifers in both the piedmont plain and alluvial plain were with geogenic high fluoride groundwater. Ali et al (2019) obtained similar conclusions for the fluoride contaminants in phreatic groundwater, and also pointed out that the arid climatic conditions may potentially aggravate the geogenic fluoride contamination through promoting the evaporation process, etc.…”

Phreatic groundwater plays a significant role in the water supply for human communities, especially in water scarce regions. This research was conducted to investigate the hydrochemistry and contamination of phreatic groundwater and their constraints on drinking water supply in a semiarid region of the North China Plain. A total of 49 phreatic groundwaters were collected for the hydrochemical analysis. The results suggested the phreatic groundwater had a slightly alkaline nature. Although the groundwater had a large variation of salinity with the TDS of 172–1,875 mg/l, most groundwater was moderately-hard fresh and of HCO3-Ca type. Contaminants of NO3−, NO2−, NH4+, Fe, F−, Zn, Mn were detected, but only NO3−, NO2−, NH4+, and Fe were found exceeding the drinking water desirable limits at some sites. The nitrogen contaminants were from anthropogenic inputs (urban sewage effluents and agricultural fertilizers) and mainly distributed in the central study area. The anthropogenic inputs of nitrogen contaminants also elevated groundwater salinity. Among the exceeding contaminants, only NO3− would pose a potential health risk to water consumers. The existing health risks by NO3− ranged from medium risk (HQ of 1–4) to high risk (hazard quotient > 4) for all populations, and most risks were categorized into the medium risk rank. Groundwater F− was also found with health risk at some sporadic sites although it did not exceed, only approached, the desirable limit. Its health risk was only to infants and categorized into the medium risk with the maximum HQ of 1.55. Most phreatic groundwater (83.67%) in the study area had relatively good quality and was suitable for domestic usage with the EWQI value below 150. Others belonged to the poor (EWQI of 150–200) and extremely poor (EWQI > 200) quality categories, and mainly distributed in the urban Gaocheng. Thus, it is recommended to pay attentions to the anthropogenic contaminants inputs into phreatic aquifers in human activities areas.
