ABSTRACT
Even though rainfall is thought of as a source that is free from contamination, human activities, especially those in the industrial and agricultural sectors, contaminate this clean kind of water. This study was conducted in two regions (Kwashe industrial area and Gara natural area) for the evaluation of rain water quality and indirectly the comparison between the evaluation of air pollution load created in both areas in Duhok governorate, the Kurdistan Region of Iraq. For this investigation, seven samples of each area were collected in the months of January and February 2023 during rainfall and they were compared. After data collection, a statistical analysis was carried out to determine the variables that affected rainwater quality. According to the current study, the first rain's water quality was significantly worse than the second rain's due to pollution. It was determined that there was a substantial difference between the first and second rain, favoring increased air pollution in the industrial region. The variation in pollutant concentrations of rainfall provides a general idea of the area's air pollution load. The outcomes of the quality evaluation program largely agreed with those found by a number of other researchers. The findings of the rainwater quality test show that pH values were lower in the Kwashe area and that some values throughout the research period exceeded the WHO-recommended limits for transportable. The results of the quality analyses indicate that it is not recommended to drink rainwater that has not been treated when it falls directly on an industrial area since it poses a health risk. The most samples of rainwater that were taken at the study site were inside of acceptable ranges for drinking use, except pH in industrial area. pH, EC, TDS, DO, alkalinity, acidity, hardness, Ca2+, Mg2+, COD, BOD, Cl-, and etc. were among the water quality metrics measured. The pollutants in the rainwater can be removed and before being used as drinking water, it should often go through some form of filtration treatment to reduce the sediment load.
