Data Analysis Considerations in Producing 'Comparable' Information for Water Quality Management Purposes - (Technical Report 01-01) - The purpose of this report is to review the current statistical analysis procedures used by a variety of monitoring entities to produce water quality information and to provide insight into the issues surrounding the difficult task of selecting methods to analyze water quality data in support of management's 'legal' monitoring requirements.

Towards a Definition of Performance-Based Laboratory Methods - (Technical Report 01-02) - This paper presents the MDCB's position concerning the need for, and the issues regarding, the implementation of a performance-based system for water quality monitoring methods.
