ASSESSMENT OF MARSH WATER QUALITY IN THI-QAR AT SPECIFIC STATIONS FOR TWO SEASONS OF THE YEAR

Abstract

The aim of this study is to assess the water quality of the marshes in Thi Qar Governorate by analyzing the physical and chemical properties of water at selected stations during two different seasons of the year (winter and summer). Water samples were regularly collected from several sites, including Al-Sanaf Marsh, Abu Subait, and Al-Amalaq, and laboratory analyses were conducted using specialized equipment such as a pH meter, electrical conductivity meter, and turbidity meter, in addition to measuring the concentrations of essential ions such as sodium, potassium, calcium, and magnesium. The results showed a significant variation in pH, total hardness, total dissolved solids, and electrical conductivity between the two seasons, with higher values observed in summer due to increased evaporation rates and reduced inflow of freshwater. Increased salinity and turbidity levels were also noted, indicating the impact of environmental factors and climate changes on water quality in the marshes. This study underscores the importance of regularly monitoring water quality to maintain ecological balance in the marshes and ensure the sustainability of water resources for the local population. It also recommends adopting sustainable strategies for water resource management and pollution reduction to preserve the marsh environment as a vital source of biodiversity and local economic activities. The objectives of the research are: to sustainably preserve natural resources and the economic activities of its inhabitants in order to achieve sustainable development goals and choose sustainable methods that are compatible with the nature of natural and environmental resources and are consistent with the nature of economic activities in the region. It can be considered local, but its impact is regional and international.
