Monitoring for Environmental Water Quality of Ramadi City: Influence of Temperature upon Chemical and Microbiological Characteristics

Abstract This work aims to assess the impact of water temperature on the chemical, physical and biological characteristics of water in water samples collected from the Euphrates River, water treatment stations, tap water and water in homes equipped with filter plants in the city of Ramadi, Iraq, during the period from January to November 2024. Parameters like pH, EC, ions (Na + , K + , Ca 2+ , Li + , Ba 2+ ), heavy metals (Cr, Ni, Pb, Zn, Cu, Fe, Cd, Co), TDS, TSS and microbial contents were estimated. During hot season Higher levels of all heavy metals except Manganese were reported compared to wet season. Concentration of Barium, Chromium and Nickel were higher than WHO standards during the hotter months. Despite this, most parameters, including pH and electrical conductivity, remained within acceptable limits. The presence of pathogenic bacteria was observed in raw river water but absent in treated and filtered samples. The study underscores the influence of temperature on water pollution dynamics and recommends enhanced monitoring and treatment strategies to safeguard public health.
