Water quality management is fundamentally concerned with maintaining the chemical integrity of water so that it remains safe for drinking, agriculture, industry, and ecosystem sustainability. Chemical parameters serve as measurable indicators of contamination, pollution sources, and the overall suitability of water for different uses. These parameters reflect both natural geochemical processes and anthropogenic influences such as industrial discharge, agricultural runoff, urbanization, and improper waste disposal. Understanding these chemical characteristics is essential for preventing man-made disasters such as toxic contamination events, groundwater pollution, eutrophication, and large-scale public health crises. One of the primary chemical parameters of concern is pH, which indicates the acidity or alkalinity of water. The pH level influences chemical reactions, solubility of metals, and biological availability of nutrients and toxins. Water with low pH can be corrosive, leading to the leaching of heavy metals such as lead and copper from plumbing systems. High pH levels can reduce the effectiveness of disinfection processes and cause scaling in industrial systems. Sudden changes in pH may indicate chemical spills or industrial contamination, which can result in ecological damage and infrastructural degradation. Dissolved oxygen (DO) is another critical parameter, reflecting the capacity of water to support aquatic life. Although DO is influenced by physical and biological factors, its depletion is often linked to chemical pollution. Organic waste discharge increases microbial activity, which consumes oxygen during decomposition. Low DO levels can lead to hypoxic conditions and massive fish kills, a common feature of man-made environmental disasters. Chemical pollutants that increase biochemical oxygen demand (BOD) and chemical oxygen demand (COD) are therefore closely monitored. BOD measures the amount of oxygen required by microorganisms to break down organic matter, while COD indicates the total oxygen required to oxidize both biodegradable and non-biodegradable substances. Elevated BOD and COD values signal organic and chemical pollution from sewage, industrial effluents, and agricultural runoff. Nutrients such as nitrates and phosphates are significant chemical parameters in water quality management. While essential for plant growth, excessive concentrations due to fertilizer runoff, sewage discharge, and detergent residues cause eutrophication. This process leads to algal blooms that block sunlight, deplete dissolved oxygen, and release toxins harmful to humans and aquatic organisms. Nitrate contamination in drinking water poses serious health risks, particularly methemoglobinemia or “blue baby syndrome” in infants. Monitoring nutrient levels is thus crucial for preventing ecological imbalance and public health emergencies. Salinity and total dissolved solids (TDS) represent the concentration of dissolved ions, including sodium, calcium, magnesium, chloride,
