Introduction of a case where iron exceeding the standard value was detected in drinking water just before the completion of new hospital construction.
This is an introduction to a case where iron exceeding the standard value was detected in drinking water just before the completion of a new hospital construction project. One example of detecting iron is corrosion of steel pipes. However, this is unlikely in a new construction site, so an investigation of the water supply system revealed that there was a mistake in connecting the water supply pipes and the utility water pipes. Additionally, our company has also identified foreign substances using advanced equipment and a rich database. [Overview] ■ Issue - Detection of iron exceeding the standard value in drinking water just before the completion of new construction ■ Solution - Conducted an investigation of the water supply system - Determined that there was a mistake in connecting the water supply pipes and the utility water pipes [Be cautious of such troubles at new construction sites!] ■ Water may stagnate in the pipes for a long time, leading to the possibility of general bacteria and TOC (total organic carbon) exceeding standard values ■ If the water source is well water, components from the soil may leach out, causing iron, manganese, and fungi to exceed standard values.
