###### Abstract
It effectively communicates water quality trends to policymakers and the general public [1]. Specifically, a WQI consistently summarizes water quality data, offering a straightforward assessment of the drinking water quality from a water supply source [2]. A WQI is invaluable for assessing water quality at specific times and locations. It consolidates various water quality parameters into easily understandable information, benefiting state agencies and the public alike. In today's world, access to safe freshwater sources, particularly groundwater reservoirs, is critical. However, these sources are being increasingly impacted by both natural processes and human activities [3; 4; 5; 6]. Changes in the physicochemical characteristics of water quality result from a combination of anthropogenic factors and various natural processes. Human activities significantly affect water quality, with this trend escalating rapidly in developing countries worldwide. To protect freshwater resources, it is essential to develop comprehensive water quality monitoring programs. These programs should be designed based on existing water quality standards, anthropogenic impacts, and 'use' criteria [7]. Water quality is a crucial concern in water resource management and environmental monitoring, encompassing three main categories (physical, chemical, and biological parameters), each with numerous specific indicators [8]. However, when dealing with a large number of samples and monitored parameters, evaluating and presenting water quality as a single unit becomes challenging [9]. This is where a water quality index (WQI) plays a crucial role. It condenses the measurements of selected parameters into a single dimensionless number, simplifying the representation of water quality [10]. There are several models of WQI that identify the level of water quality. Several of these models are presented in the study by authors [11] who provide new approaches and starting points for examining water quality. In developing countries, where budget constraints often limit extensive water quality analysis, it is essential to focus on a few critical parameters when calculating a WQI [12]. Importance and advantages: The CCME WQI (Canadian Council of Ministers of the Environment Water Quality Index) serves as an effective tool for assessing groundwater quality and communicating water health to multiple stakeholders, including policy and decision makers. It provides precise results and easily understandable water quality reports [13]. The CCME WQI has been adopted globally for evaluating water quality in rivers, lakes, groundwater, and reservoirs. It was designed and developed by the Canadian Council of Ministers of the Environment (CCME) to study the impact of water degradation on various aspects, such as human health, aquatic life, livestock, agriculture, and suitability for different uses like drinking water and irrigation. Since 2001, the CCME WQI has been widely used worldwide to assess water quality and produce comprehensive reports, identifying areas with varying levels of contamination. [14; 15; 16]. Researchers often rely on the CCME WQI to assess water quality parameters over time. While it is currently used on a case-by-case basis for surface water sources and distribution systems, its full potential as a management tool for complete water supply systems (WSSs) has yet to be fully recognized on a global scale [17]. In one study conducted in Fort Lake, Belgium, Karnataka, India, the CCME WQI was applied to assess its impact on aquatic life, livestock, and its suitability for recreation, irrigation, and drinking water [18]. The CCME WQI provides a versatile index template that can be tailored to the specific site and treatment considerations of drinking source water. By comparing measured water quality values to established guidelines, it generates a score from 0 (worst quality) to 100 (best quality).
