Water Quality

We are using these passive samplers to try and identify sources of pollution in the catchment and protect our drinking water from pollutants.


TO FInd out more about water quality in the catchment, visit our Catchment Data Portal.



Pollution from many sources affects water quality in the Wyre catchment. Runoff from roads and farmland as well as sediments and wastewater entering our rivers, streams and brooks can all be harmful to river life. Pesticides and herbicides washed into the watercourse when it rains can kill river invertebrates which fish and other wildlife rely on for food, whilst fertilisers high in nutrients can reduce plant diversity and cause algal blooms. Sediment which enters the river when washed off bare arable fields or from river banks trampled by livestock can smother sites where fish have laid their eggs.

Water quality also affects our drinking water. Water in the northern reaches of our catchment provides drinking water for an estimated 650 thousand people. Treatment required at the water treatment works to remove pollutants so that it is fit for human consumption is extremely costly, and in some cases, certain pollutants (such as metaldehydes, found in slug pellets) cannot be removed.

We are working with landowners and land managers to reduce the amount of polluting substances ending up in our river, as well as raising awareness of how members of the public can reduce their impact on our river.
