■ Can it be used for drainage measurement records? According to the Water Quality Pollution Prevention Act Enforcement Regulations, the measurement results of discharged water must be recorded in a water quality measurement record sheet and kept for three years. If a certificate is received from a measurement certification business stating the details of the sampler, analyzer, and measurement items in the record sheet, those entries can be omitted. In this case, the certificate should be kept along with the records. ■ Is it a separate registration from water quality testing for water supply? When water supply operators outsource water quality testing, the outsourcing parties must be either local government agencies or those registered by the Minister of Land, Infrastructure, Transport and Tourism and the Minister of the Environment, as stipulated by the Water Supply Act. This is a different system from the registration under the Measurement Act, so care must be taken to avoid confusion. ■ Things to organize before making a request 1.
