Please leave the water quality testing for switching to a direct supply water system to Naito Environment!
Tap water is essential to our lives. The materials used to supply tap water can be broadly classified into two categories: materials (equipment) used in the water purification process and transportation process at water facilities, and materials (water supply tools) that branch off from the distribution pipes installed by water service providers. "Leaching tests" are conducted to confirm whether harmful substances leach out from these materials when they come into contact with water. At Naito Environmental Management Co., Ltd., we prepare leachate from water supply materials and tools, and test whether this leachate meets the standard values for leaching criteria set by law. The analysis items and frequency vary depending on the material differences, but please feel free to contact us if you have any questions. For more details, please inquire or refer to our catalog.
