The culprit makes the Red River

Down the Red River a few more kilometers, the water appears with water, precipitate, and colors like five-colored clouds .

>> Finding the cause of the Red River "sharpness"

As the previous article reflected on the situation of heavily polluted Red River water flowing through Lao Cai province. In an effort to trace the cause of the incident, we went upstream upstream where the Red River entered into Vietnamese soil. Unfortunately, it is not only the territory from the Nam Thi confluence from Ha Khau that bordering Vietnam with China, there are black and cloudy colors and the scum of water precipitating red, green yellow, white stinks , fishy, ​​foul . but from here upstream upstream hundreds of kilometers has appeared on the phenomenon, even the pollution situation is much heavier than the area of ​​Lao Cai City.

Place the Red River flowing into Vietnamese soil

Follow the winding, provincial road. From Lao Cai City for more than 3 hours, we were present at Lung Po village in A Mu Sung commune (Bat Xat). Welcome us on the patrol house of the border guards A Mú Sung and Mr. Luat - border guards said: This place has a Po Po stream flowing into the Red River. This is considered the first place of the country and it is often called the place where the Red River flows into Vietnamese soil.

If it continues to rise upstream from the 20-km Lung Po and Red River junction, there will be a cassava starch processing factory. This plant is located on the banks of the Red River and discharges wastewater into the river. In addition, along the river, it runs through Bat Xat district. If you look carefully, you will see a big factory on the border. As a guess, it could be an alcoholic plant, they also process cassava to produce alcohol and alcohol. But it could also be a rubber latex processing factory .

Black water

Following the instructions of the A Muc Sung Border Guard soldiers and the local people, we swept the Red River, passing Ban Voc commune, Bat Xat district, about 40km from Lao Cai City to the northwest. Standing on the high hill observed, everyone saw a large industrial factory, a huge column of smoke rose behind the vast rubber forests. According to our observation, from the bank of the Red River to this factory is only about 100m and there is a stream flowing into the river. If you look carefully you can see that the water of the stream flowing into the Red River is black.

In addition to the above information, the soldiers of Border Guard A Mú Sung also added: In the past, the exploitation of bandit ore from the other side of the border was strong. A large amount of waste soil from mining activities is poured into the river bank. Although your country may have prevented, there are still a number of metal ores in the disposal sites that are oxidized, then follow the flow of water downstream.

Yellow water scum appears along the Red River

Leaving the guard station in Lung Po village, we joined the Lao Cai Environmental Inspection Group to locate a landmark of the boundary between our country and China. Mr. Nguyen Duy Hung, Head of the Water Resources Management Test Unit, held the exact coordinates of the position we were standing at and pointed to the Red River junction saying: The water color here is nothing to worry about. afraid, because the opaque color of the Red River remains unchanged. Except for the interchange between the Lung Po and Red River streams, there is a clear blue color.

Many scum of red water and tapioca

Down the Red River for several more kilometers, the water appears to be stained with water, colors and shapes like iridescent clouds . In addition, on dry sands, white powders are closed. , sticking together like rice cakes, at the same time also smelling very bad, fishy makes people breathe and nausea.

Not yet. Red river water also appears strange phenomena. These are ignorant substances that flow into a water stream with a high density and density. Mr. Le Manh An, Deputy Head of Environmental Control Department of Lao Cai province, took test water samples into a jar. In the country, there are many wastes which, according to Mr. An, are cassava fiber.

Waste pipes from China.

According to Mr. Hung, these scum with the color of the scum appeared on the territory of Lao Cai City. Mr. Hung said: In Lao Cai, in recent years, there has not been any year when the rainfall is low as this year, the water source on the headwaters has been blocked by hydropower plants so this season the river becomes exhausted. The black and yellow scum that flooded the Red River grounds is not decomposing algae but is the waste of the Chinese factories of cassava discharging, the contaminants that are left behind make the water colors have yellow scum like that. In other seasons, the amount of water that the Red River rises leads to the dumping of the wastes and when the water recedes, these pollutants settle on the rivers. According to our observation, these yellow stains also appear on the other side of China.

Waste and fishy odor of water

Holding a small bottle of water samples to check, but Mr. Le Manh An was really surprised and had to say: This part of the water flows very smoothly, the color of this river is not clear but has become muddy. . The layers of waste are washed away by the flow and drifted to the shore carrying the foul smell of decomposed residues. I questioned Mr. An because the previous upstream did not have this phenomenon, but it was like that. Mr. An said: The previous sections of the river are deep and more flowing, so they have swept away all kinds of waste, this location is the vicious areas, the wastes will drift here.

Hero discovered strange white powder.

The people in the group recognized the fishy smell of water with the waste residues that formed into membranes that were very similar to those under the downstream. " The river suffers from the same type of waste. It is common knowledge that ordinary people are very foul-smelling, polluting the environment, and how much pollution will definitely need analysis. price scientifically, "said An.

Going along the Red River, at each point, Luu Duc Cuong, deputy director of the Environmental Monitoring Center, used equipment to test the pH of the water. The concentrations of the measured points ranged from 7.5 to 7.9. Mr. Cuong said, with the current pH, we have nothing to worry about. However, this is a strange change because before the pH on the Red River was only at threshold 7. Also according to Mr. Cuong, the reason is that the pH level is only above 7 because of the continuous dissolution of water. .

Who is the culprit?

Going along from the upstream of the Red River, we observe dozens of drains on your country side and discharge waste directly to the Red River. It is not known whether it is a factory, a factory or a population, but it also affects badly the Red River water source.

According to the people who go to the market to China: The factories extract cassava starch, alcoholic . are located along the banks of the Red River , may have discharged into the environment. But it's all in guessing. According to Hung, it's hard to conclude right now.

" From now on, we are only guessing the culprit poisoning the Red River, but also announcing it is another. Immediately after testing the active ingredients in the country, we will send a notice to the authorities. ", Mr. Hung said.
