چکیده English

Introduction
The quality of groundwater supplies for various uses is a major concern in the fields of public health and the environment in arid and semi-arid countries. The environment and human health may be negatively impacted both directly and indirectly by the quality of groundwater, which can be significantly impacted by a variety of harmful human and natural factors. A person’s health and well-being depend on having access to clean, safe drinking water. Examining the quality of water facilitates the identification of possible pollutants, including infections, heavy metals, and chemical pollutants, which may pose a health risk to humans when ingested. To protect public health and avoid waterborne illnesses, it is essential to ensure the quality of drinking water through careful analysis and monitoring. As the main resource for irrigation, water is essential for agriculture. The entire productivity of agriculture, crop growth, and yield are directly impacted by the quality of the water used for irrigation. Researchers can determine elements such as salt, alkalinity, and the presence of dangerous compounds that may negatively impact plant growth by examining the quality of water. Comprehending the quality of water facilitates farmers in making well-informed choices about crop selection, soil management, and irrigation techniques, thus enhancing agricultural productivity and sustainability. Water is used in many different industries for activities such as manufacturing, cooling, washing, and product creation. To guarantee the efficiency of these procedures and to avert any environmental contamination, it is essential to investigate the quality of water in industrial settings. Industrial operations can release organic molecules, heavy metals, and chemical byproducts into water sources. By minimising the release of dangerous compounds, implementing appropriate treatment technologies and adhering to environmental requirements, enterprises can protect human health and the environment by using water quality analysis. Public health is strongly impacted by water quality because tainted water can spread illness and present serious health hazards. Health authorities can determine potential health risks, set safe water consumption limits and regulations, and implement suitable water treatment techniques by analyzing water quality. Frequent water quality monitoring and evaluation helps prevent epidemics of waterborne illnesses, safeguard populations from illness, and maintain public health.
The quality of groundwater in the Mimeh Plain is crucial because it is one of the most significant plains in the province of Isfahan and is heavily dependent on groundwater resources for industrial, drinking, and agricultural purposes. It significantly affects the general public’s health and hygiene in this area . Therefore, various actions are needed to improve the groundwater quality of the Mimeh Plain for different purposes. These actions include determining and addressing the causes of water pollution, treating groundwater for various purposes, creating efficient techniques for managing and conserving water resources, and maximizing their use to enhance public health and safeguard the environment. Research has been conducted on these subjects.

Methodology
Data on the chemical components of eight deep well samples from the Mimeh Plain groundwater aquifer in the years 2022–2023 were examined to create this study. Calcium (Ca), potassium (K), magnesium (Mg), sodium (Na), bicarbonate (HCO3), chloride (Cl), and sulfate (SO4) were among the elements examined. The Stiff, Piper, Wilcox, and Schoeller diagrams in the AquaChem program were used for the analysis.
Primary water types were identified using the Piper diagram, which is a helpful tool for classifying water. The host rock and geological setting that impact water quality were determined using the Stiff diagram. While the Wilcox diagram was used to categorize water quality for irrigation, the Schoeller diagram was used to evaluate the quality of drinking water. Utilising these waters can present health risks due to sedimentation and water buildup. In addition, it may result in a decrease in the cross-sectional area of pipes in systems that distribute and transmit water. Guidelines from the World Health Organization state that water that is prone to sedimentation can be uncomfortable for the gastrointestinal tract, particularly in children. Consequently, it is also important to assess water quality for industrial uses. The groundwater quality in the research area was evaluated for industrial usage using the Langelier Saturation Index and Ryznar Index.

Conclusion
This investigation was conducted to examine the quality of groundwater in the Mimeh Plain for a range of agricultural, drinking, and industrial applications using eight piezometric wells within the study area. The findings from the hydrogeochemical analysis of the wells indicate that the Jowshan Road and Koushk-e-Chah Enghelab wells are of the bicarbonate type, whereas the remaining wells are classified as chloride type. In general, the results obtained for the classification of groundwater quality reveal that the Aliabad-e-Arteshi, Dakhel-e-Khosrowabad, and Saleh Khatun wells are in an unfavorable state for agricultural, drinking, and industrial purposes. Overall, only the Koushk-e-Chah Enghelab and the first well of Jowshan Road are deemed suitable for agricultural and drinking uses. Water Treatment and Management: The advancement of water treatment technology depends critically on the study of water quality. A comprehensive understanding of the pollutants present in the water is essential for the effectiveness of water treatment techniques, including filtration, disinfection, and chemical treatment. The process of water quality analysis facilitates the identification of suitable treatment techniques, streamlining of treatment procedures, and creation of novel technologies for the elimination of particular contaminants. Researching water quality also aids in the effective distribution, allocation, and conservation tactics related to water resources. The economic implications of water quality are of significant importance. The presence of contaminants in water can escalate healthcare expenditures owing to waterborne diseases and the consequent need for medical intervention. Within the agricultural domain, inadequate water quality can lead to diminished crop yields and economic deficits for farmers. Industrial sectors may encounter financial burdens attributable to regulatory penalties, expenses associated with remediation, and potential legal actions arising from incidents of water pollution. The study of water quality allows for the potential mitigation of economic losses through the adoption of appropriate management strategies, the efficient allocation of resources, and the implementation of preventive measures. Information regarding the quality of water is of utmost importance for the effective planning and management of water resources. Gaining an understanding of the quality of the available water sources aids in assessing the appropriateness of water for various uses and optimizing the distribution of water. By considering the data related to water quality, policymakers and managers of water resources can make well-informed decisions on the allocation of water, the development of infrastructure, and the establishment of measures for the protection of water quality. This significantly contributes to the sustainable management of water resources and ensures the long-term availability of unpolluted water for diverse purposes.
