Impacts

This indicator takes an overview of the condition of surface water bodies in England in 2019; it relates to rivers, lakes, estuaries and coastal waters. For rivers, invertebrates and the combined test for macrophytes and phytobenthos (plants and algae) are reported to indicate biological quality, where 76% and 45% of tests carried out passed for the water bodies assessed respectively. For lakes, the representative biological element shown is phytoplankton with 52% of water bodies assessed passing. Saltmarsh is shown for estuaries and coasts and reflects the extent of habitat and show 36% and 50% of water bodies monitored, pass the test respectively.

  1. Results are based on the numbers of water bodies assessed and represent the achievement of good or better status. Ecological status is assigned using various water, habitat and biological quality tests. Failure of any one individual test means that the whole water body fails to achieve good or better ecological status (the “one out all out” rule).

This indicator takes an overview of the condition of groundwaters in England in 2019. Of the groundwaters tested, 75% passed (good status) water quantitative tests and 45% passed (good status) chemical (qualitative) tests.
