The presence of SARS-CoV-2 virus in water resources and the transmission of diseases caused by it is one of the factors threatening the quality of water resources. This study for the first time concentrates on the presence of SARS-CoV-2 in water resources an urban location. In the present study, the samples were collected from known depth (30-50 cm) of rivers, dams and lakes. In each sample of water collected, different parameters such as residual chlorine, pH (phenol red), turbidity, total dissolved solids and temperature were also measured. Out of 267 samples, two samples were detected to be positive which their Ct values were 34.2 and 35.67. The existence of viable form of this virus in water and wastewater may be associated with issues for providing public health and difficulties in implementation of pandemic control strategies, and this situation can be exacerbated in developing countries that do not have adequate access to sanitation and safe water.
水资源中存在严重急性呼吸综合征冠状病毒2（SARS-CoV-2）病毒及其引发的疾病传播是威胁水资源质量的因素之一。本研究首次聚焦于城市地区水资源中SARS-CoV-2的存在情况。在本研究中，样本取自河流、水坝和湖泊已知深度（30 - 50厘米）处。在采集的每个水样中，还测量了不同参数，如余氯、pH值（酚红）、浊度、总溶解固体和温度。在267个样本中，检测到两个样本呈阳性，其Ct值分别为34.2和35.67。这种病毒在水和废水中的存活形式的存在可能与公共卫生问题以及大流行控制策略实施困难有关，而在缺乏充足卫生设施和安全用水的发展中国家，这种情况可能会加剧。
