Purifying water
to help save
the otters

It’s not just about the otters; Samsung has led multiple projects to revive Osan Stream.
We took contaminated water used in the chip production process and purified it so thoroughly the water quality ended up better than even government standards.

We also sponsored the Butterfly Road Project, which increased northern pipevine plants to help develop the local ecosystem. Northern pipevines are the only source of food for the dragon swallowtail butterfly, which had been commonly found in Osan Stream.

When the northern pipevines disappeared,
the dragon swallowtail butterflies became endangered. Through our support, the Blue Dongtan Volunteer Group and Osan branch of the Korean Federation for Environmental Movement were able to work on the Osan Stream Butterfly Road project and help
the pipevines and butterflies return.
