Water Quality

The following section describes the water quality of study area of the Thames Estuary.

Water quality data is predominantly collected by the Environment Agency in response to legislative requirements. Data is then compared against environmental quality standards (EQS), which are designed to protect the environment and human health. In the Thames estuary study area there are a number of applicable EC Directives which trigger a requirement for monitoring. These Directives include::
