Investigating parasitic protozoa and studying some properties of drinking water at the water treatment plant Al-Dour district – Salahalddin

Abstract

The study was conducted in Al-Dour district, which is located within Salah Al-Din Governorate. The current study included various tests and analyses of four water treatment plants, including microscopic examinations to search for some parasites using a microscope. It also included other aspects and tests of some of the properties of the water from the Al-Dour district water treatment plant. This was done through tests that were carried out regarding the physical and chemical properties of the aqueous samples.

     The results regarding the examination of the studied samples, both visually and microscopically, showed the absence of parasites, indicating the quality of the water suitable for human use. Other water tests were also within standard specifications, whether physical or chemical, for the period from August 2024 to January 2025. The pH analysis recorded values ​​close between 7.25 and 8.55, and turbidity was recorded between 2.41 and 45.3 NTU. Total alkalinity recorded varying results ranging from 256 to 106 mg/L, while the sulfate analysis results recorded values ​​between 88.366 and 57.166 mg/L, While the oxygen concentration recorded values ​​of 6.2 – 3.9, the analysis of the biological oxygen demand ranged between 1.7-0.4 mg/L. As for the heavy elements, they had low values, as nitrates recorded values ​​between 2.7-0.1 mg/L, and iron 0.02-0.14 mg/L
