To make our rivers and streams clean again, we need to be able to work out where the pollution is coming from. Not all fields will be polluting. Two things make a field a problem:
- a field that produces lots of pollution;
- a field that is easily connected to rivers, lakes, or groundwater.
To identify the locations that are a problem, we have developed SCIMAP, a joint project between Durham and Lancaster Universities. SCIMAP is supported by the U.K.’s Natural Environment Research Council, the Eden Rivers Trust, the Department of the Environment, Food and Rural Affairs and the Environment Agency.
We hope that SCIMAP will be used to help decision-makers, including governments, non-governmental organisations, land owners etc. to work out where to prioritise activities that protect the water environment, and so make our water clean again.
On this web-site, we provide a basic description of the science base that we are developing, we illustrate the SCIMAP approach and how it works, and we provide material for further learning about the approach. You can also download the SCIMAP software.
