Still, I am very worried about tap water, but the situation in Daecheongho, a source of drinking water for 5 million people in the central region, is not good these days. A large amount of garbage that has been pushed in the rainy season has floated like a large island, and the heat is worsening to the green algae, which is a concern for water quality deterioration.

This is Lee Yong-sik.

Upstream of Daecheongho in Okcheon, North Chungcheong Province.

On the lake, a trash island with a soccer field.

Garbage that flowed into the rainy season was caught in a barrier and floated widely.

Waste tires, buckets and even rubber boats stand between dry grass and branches.

left even where raised about 3km upstream from The rubbish that has been pushed is floating.

About 210 thousand tons of garbage flowed into the lake due to the heavy rain of 210 mm that was poured into the Daecheongho watershed last week.

It is about 35 kilometers from the intake tower, but it has to be cleaned up in a hurry to prevent water deterioration.

There has already been light green algae around the garbage.

As the rain stops, the temperature rises rapidly, and the green algae spread, and thus, the green algae is covered at the edge of the lake.

The green algae in the water is so thick that you cannot see the front, but when you float the water, the green algae grains are full of water.

The Ministry of Environment and Korea Water Resources Corporation decided to collect all the waste within two weeks, but blocking green algae that spreads in the heat is another challenge.
