About this book

A new and superior approach to classification, called the General Quality Assessment (GQA) Scheme has been developed to replace the National Water Council (NWC) classification. This report describes the chemistry component of the new scheme and the results which were obtained when it was applied to the assessment of river and canal quality for the periods 1988-90 and 1991-92 for England and Wales.
