2012-2013年期间，在哈里德瓦尔（北阿坎德）对恒河运河水的物理化学参数进行了评估，其中包括两个不同的地点，即：Bhimgoda Barrage（站点1-控制站点）和Bahadrabad（站点2-污染站点），运河水从高度商业和工业区流出，带有污染负荷。调查期间，最大浊度（287.72 ± 56.28 JTU），总固体（1167.60 ± 303.90 mg l−1），游离CO2（1.88 ± 0.22 mg l−1），总硬度（60.14 ± 1.13 mg l−1），pH（7.1 ± 0.13），硝酸盐（0.048 ± 0.010），亚硝酸盐（0.019 ± 0.001），生化需氧量（2.866 ± 1.098），化学需氧量（6.8 ± 2.61）和磷酸盐（0.087 ± 0.015），而最小速度（1.71 ± 0.19 ms−1），与站点1相比，站点2在季风季节记录到透明度（0.12 ± 0.08 m）和溶解氧（7.95 ± 0.44 mg l−1）。 结果表明，浊度、总固体、pH、溶解氧、游离CO2和总硬度的平均值在不同采样点间差异显著（p< 0.05）。记录的部位1和部位2的浊度均高于允许限值。2号站点的浊度远高于1号站点，因此被视为污染较重。研究的参数值在季风季节和夏季在站点2相比，站点1。结果表明，大多数的理化参数从恒河运河系统内或外围相比，ISI和WHO的饮用水的允许的限制，因此可能适合于家庭用途，但它需要明显的考虑，由于气候的剧烈变化和污染的增加。
Assessment of physicochemical parameters of Ganga Canal water was carried out during 2012–2013 at Haridwar (Uttarakhand) with two different sites, i.e., Bhimgoda Barrage (site 1—control site) and Bahadrabad (site 2—contaminated site), where canal water flows with loads of pollution from highly commercial and industrial areas. During investigation, maximum turbidity (287.72 ± 56.28 JTU), total solids (1167.60 ± 303.90 mg l−1), free CO2(1.88 ± 0.22 mg l−1), total hardness (60.14 ± 1.13 mg l−1), pH (7.1 ± 0.13), nitrate (0.048 ± 0.010), nitrite (0.019 ± 0.001), biochemical oxygen demand (2.866 ± 1.098), chemical oxygen demand (6.8 ± 2.61) and phosphate (0.087 ± 0.015), while minimum velocity (1.71 ± 0.19 ms−1), transparency (0.12 ± 0.08 m) and dissolved oxygen (7.95 ± 0.44 mg l−1) were recorded in monsoon season at site 2 in comparison with site 1. The mean values of these parameters were compared with WHO and ISI standards and found significant differences (p< 0.05) in the mean values of turbidity, total solids, pH, dissolved oxygen, free CO2and total hardness with sampling sites. The turbidity of both the sites 1 and 2 was recorded above the permissible limit. Turbidity of site 2 is much higher than of site 1, so it is counted as more polluted. The values of the studied parameters were more during monsoon season and summer season at site 2 as compared to site 1. The results indicated that most of the physicochemical parameters from Ganga Canal system were within or at periphery in comparison with permissible limit of ISI and WHO for drinking water and therefore may be suitable for domestic purposes, but it requires perceptible consideration due to intense changes in climate and increase in pollution.
