ChaMP is undertaking a variety of research to help inform the project and sharing this information to assist the work of others. We’ll be gathering data and evidence on the issues, and monitoring the success (or otherwise!) of the solutions.
For example we currently have a PhD underway to assess the potential for urban pollution to the groundwater, and this autumn will be monitoring a trial of cover crops to reduce the amount of nitrate lost through soil.
We’re also be working with the British Geological Survey and others to improve the knowledge of karst features in the Brighton chalk block. Karst features such as swallow holes and fractures in the chalk allows pollution to move very fast and pass through to the aquifer without the benefit of filtration in the chalk.
The map here shows where some of the known karst features are located. But we need to improve this knowledge so we are better able to identified areas which are particularly vulnerable to pollution.
