Is it safe to drink tap water in Sendai Japan? The answer depends on the contaminants found in the water, the location of the source and the water treatment process.

The contaminated water in Sendai is from Lake Biwa, the largest lake in all of Japan. The lake is fed by snowfall that melts on the mountainsides in the area and flows into the ocean. Water that falls out of the mountain passes through the forest and into the river, where it is distributed to rivers and streams. Some of this water comes into lakes and reservoirs as well, although the amount is smaller.

Many of the impurities that make up this water are from human activities. Most of the waste material that ends up in the water that travels out of the mountains has been deposited in the sedimentary layer of the water. Once the water is stored in the lake or reservoir, the impurities become embedded in the sedimentary layer and have a time to show up on any sedimentary layers.
