Assessment of Water Quality of the Marsh of Dalmaj Based on some Physico-Chemical Parameters

Abstract

Abstract As a result of entrenched industries, human causes, urban habitats, water pollution and sewage discharges into the waters have contributed to the decline of animal populations in Dalmage Marsh, which is home to thousands of species. We use procedures approved by the World Health Organization to evaluate physical and chemical properties in three different sites of the marsh of Dalmaj, which may pose a significant risk to public health and to all aquatic organisms. The rates of physical and chemical properties for the months studied were as follows: pH (7.708), temperature (19.15) °C, and dissolved oxygen (DO) (5.611) mg/L, Biochemical Oxygen Demand (BOD) (2.126) mg/L, Electrical Conductivity (EC)(28719) μS/cm, Total Dissolved Solids (TDS)(21767) mg/L, Turbidity(18.39) NTU, Total Hardness (TH)(11304) mg/L, Calcium(397.7) mg/L, Magnesium (2330) mg/L, NO3 (7.759) mg/L, and chloride (5407) mg/L. The results also showed fluctuations in physical and chemical parameters at each of the sites during the study months, which indicates an increase in water pollution due to human activities in the waters of the Dalmaj. We recommend conducting more studies every year to monitor pollution in Dalmaj water that changes the values of chemical and physical properties.
