Current Issues and Sites

We will post information about the sites we receive the most enquiries about on this page. Please follow the links below to find their fact files, or scroll to our Newsfeed at the bottom of the page to read our latest update.


  • Lower Hare Farm Landfill - an inert landfill site that faced local opposition when it applied for an environmental permit.



  • Our pollution incident response in Exmouth - following a number of sewage pollution incidents since 2023, we have been investigating the events, monitoring to understand the impact on the environment and ensuring South West Water (SWW) implement a sewerage system fit for the future.


  • Hemerdon Tungsten Mine - a critical mineral mine between Plymouth and Dartmoor is seeking to restart operations. The site attracted significant local concern under previous operators because of low frequency noise affecting nearby communities.


  • Septic Tank Waste in Cornwall - Cornwall’s landscapes and coastline are some of the most treasured in the country. Protecting them means making sure septic tank waste is handled safely, so it doesn’t harm people, wildlife or the places communities rely on. Visit this section to learn more about septic tank waste management.
