About use of home well water

In the highly urbanized city, well water is no longer clean due to changes in the surrounding environment, and may be contaminated in some cases.
In addition, pollution of wells by chemical substances is not noticed in daily management and inspection.
In order for well water to always meet tap water quality standards (51 items), chlorination, advanced water treatment, and maintenance for it are necessary to improve the water quality.
Therefore, use tap water that has been confirmed to be safe for drinking water, and use well water as domestic water such as washing water.
