In the video filmed on May 30, the water of the Minjiang River in Songpan County, Aba, southern China, has turned unusually red, causing widespread concern.

Video showed the river has a very bright red water surface. As the water continues to flow, the red has not dimmed, some people speculate that it may be factory paint flowing into the river.

On May 31, the staff of the relevant departments in Songpan County responded that the relevant situation had been reflected, and the river water was indeed unusually red on the 30th, but it was not dye or pigment flowing into the river.

After the joint investigation of the local ecological environment, water and other departments, the abnormal state of the water is about 2km, the water is brown red, after sampling has been sent to professional institutions for inspection. After testing, the heavy metals in the water samples did not exceed the standard, and the acute toxicity test result of the water quality was non-toxic.

After investigation, the coastal drinking water sources were not in the abnormal water body reach, and drinking water was not affected. At present, Songpan County is organising relevant experts to further investigate the cause of the abnormal river water.

近日，四川阿坝松潘县，岷江的河水呈现异常红色，引起广泛关注。
当地居民拍摄的视频显示，一处河流水面呈现十分鲜艳的红色，水流不断流动，但未见红色变淡，有人猜测可能是工厂颜料流入河中。
5月31日，松潘县有关部门工作人员回应称，目前已经接到了相关情况反映，30日确有河流水体呈现异常红色，但并非染料或者颜料流入河中。经过当地生态环境、水务等部门联合调查，呈现异常状态的水体约有2公里，水体呈褐红色，采样后已送至专业机构检验。经检验，水样中重金属均未超标，水质急性毒性检测结果为无毒。经排查，沿岸饮用水水源地均未在异常水体河段，饮用水未受影响。目前，松潘县正在组织相关专家对河水出现异常的原因进行进一步调查溯源。
