High levels of bacteria, minerals, or other contaminants in the water of poultry farms can have adverse effects on the natural physiology of chickens. Therefore, this study aims to investigate the physical, chemical, and microbial quality of water used in poultry farms in Ardestan, Iran.</span></span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:115%"><span style="font-family:&quot;Times New Roman&quot;,&quot;serif&quot;"><b><i><span style="font-size:10.0pt"><span style="line-height:115%">Materials and Methods:</span></span></i></b><span style="font-size:10.0pt"><span style="line-height:115%"> This descriptive cross-sectional study was conducted on water sources (Wells and Qanats) of 35 poultry farms in Ardestan during the summer of 2021.Water samples were randomly taken and send to laboratory for analysis of physical, chemical, and microbial parameters according to Standard Methods. </span></span><span style="font-size:10.0pt"><span style="line-height:115%">SPSS 16 software was applied for statistical analysis</span></span><span style="font-size:10.0pt"><span style="line-height:115%">.</span></span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:115%"><span style="font-family:&quot;Times New Roman&quot;,&quot;serif&quot;"><b><i><span style="font-size:10.0pt"><span style="line-height:115%">Results:</span></span></i></b> <span style="font-size:10.0pt"><span style="line-height:115%">With the exception of sodium, sulfates, and total hardness (TH), all other parameters fell within acceptable standard limits. Some water samples showed elevated levels of total coliforms exceeding the prescribed limits. Furthermore, the mean concentrations of heavy metals, including iron, lead, chromium, and cadmium remained within acceptable levels in all samples.</span></span></span></span></span><br> <b><i><span style="font-size:10.0pt"><span style="line-height:107%"><span style="font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Conclusion:</span></span></span></i></b><span style="font-size:10.0pt"><span style="line-height:107%"><span style="font-family:&quot;Times New Roman&quot;,&quot;serif&quot;"> Although the majority of water quality parameters in the studied poultry farms were compatible with standards limits, testing and monitoring the chemical and microbial quality of water in poultry farms is recommended on a regular basis.</span></span></span></div> Poultry, Water Pollution, Water Quality, Ardestan City. 2070 2077 http://jehsd.ssu.ac.ir/browse.php?a_code=A-10-624-2&slc_lang=en&sid=1 Fatemeh Mohebbi fmohebbi1375@gmail.com 0000-0003-3261-7075 No Department of Environmental Health Engineering, Faculty of Health, Kashan University of Medical Sciences, Kashan, Iran.
