River Water Quality Monitoring 1990 to 2024 - Dissolved Copper

This table provides the raw data from Northern Ireland river monitoring sites including Water Framework Directive monitoring sites. It covers the time period 01/01/1990 to 31/12/2024. As the dataset is in its raw state, it cannot be used to provide a status without processing. It should be noted that Limits of Detection or Limit of Quantitation would require a value to be treated as a half value for WFD calculation. In addition both altitude and alkalinity affect status calculations for some parameters.
