The Environment Agency established its Monitoring Certification Scheme (MCERTS) to deliver quality environmental measurements. The scheme is based on international standards and provides for the type-testing and subsequent product certification of instruments, the competency certification of personnel and the accreditation of laboratories.
This guidance contains the performance standards and test procedures for automatic water sampling equipment (samplers) used, for example, in monitoring of treated discharges from waste water treatment works, industrial processes, untreated waste waters and receiving waters.
