Annotation: EA additional title info: January 1994
This report reviews the background to the monitoring of priority hazardous substances in Thames region and looks at the results of monitoring carried out from 1990 to 1992. A number of issues are highlighted with respect to the monitoring strategy and the interpretation o f the data. Recommendations are made to establish plans of action for those substances which are detected in over 30% of samples, and to stop monitoring those substances which are rarely detected. Sites have also been identified where specific substances are detected most frequently or at the greatest concentrations and where some form of action may need to be considered.
