Abstract
River water quality in England and Wales improved by 28% from 1990 to 1995. This is a statement based exactly and entirely on data collected and processed by fixed and published rules and placed on Public Registers. This paper sets out how we deal with error, how we prevent error leading to wrong decisions on the action needed to improve water quality, and how we transfer the data into hit lists of priorities for action.
