Thames 21 Presentation on Urban Diffuse Pollution from CaBA Regional Learning Workshops

  1. 1. Urban Diffuse Pollution Theo Thomas, Thames21 theo.thomas@thames21.org.uk
  2. 2. Urban Diffuse Pollution Widespread, day to day pollution Catastrophic results – July 2013 Diffuse pollution significant factor in the number of rivers failing WFD
  3. 3. Stormwater run off Run off from roads, industrial, parks, gardens, golf courses On many tributaries vehicle use is a greater contributor of pollutants than industrial sites or sewage treatment works Oils – leaking engines Heavy metals – copper from brake pads & engine parts, lead from bearings and tyres, zinc from tyres Other toxic chemicals – eg. fertilisers on golf courses
  4. 4. Plumbing misconnections So widespread could be considered diffuse Pathogens Nutrients Detergents Pharmaceuticals/cosmetics
  5. 5. Investigating pollution • Citizen Science • Locating polluting outfalls from roads • Catchment Walkovers • Informal outfall spotting • Best source of information • Reporting pollution incidents
  6. 6. Further investigation • University partnerships • National Laboratory Service • Other commercial laboratories (ensure accredited by UKAS) • Local Authority Environmental Health Department
  7. 7. SW drainage maps From local authority or water company
  8. 8. Partnerships • Local authorities Highways Dept Planners Building Control Environmental Health Flood Engineer Comms Team Parks Dept Biodiversity Officer • EA • Water company • Highways agencies • Businesses • Residents
  9. 9. Solutions • Awareness raising Public and authorities • Enforcement • SuDS
  10. 10. Salmons Brook Healthy River Challenge • Catchment Restoration Fund project • Very few urban diffuse pollution projects • Creation of SuDS to tackle urban diffuse pollution in Salmons Brook Catchment • Taking a holistic approach
  11. 11. Determine a need – The A10 Catchment walkovers Local reports Local Authority Officers Water quality testing
  12. 12. Next steps……. • Stormwater drainage maps • Topographical survey to determine feasibility • Locate site
  13. 13. Next steps……. • Liaise with partners • Community engagement: Inform – regularly! Raise awareness Dispel concerns Consult? Transparency Volunteers to help with SuDS creation/maintenance • Design SuDS – consultant • Ecology survey • Permissions
  14. 14. Case study – A10
  15. 15. Current challenges • Identifying further funding • Further water quality testing – access and sediments • Liaising with partners: TW, TfL, LBE • Concurrent works • Timescales • Beasties!
  16. 16. SuDS – Idea to installation • Where are your major roads or roads that drain to your river? • Do you know of any rivers where problems have been observed? • What kind of problems do you think there are? • How would you determine what the problem is? • Who do you need to involve? • How would you secure the involvement of those you have identified? • Road run-off solutions? • Misconnection solutions? • Sediment solutions? • Other problems? • Is there space for SuDS?
  17. 17. • Sources – Local Authority? Highways Flood management Environment Agency/Defra? Businesses? • How would you make the case? What are the drivers? • Any planned schemes you can become a part of? Funding
  18. 18. Future support • Available to give guidance (inc. misconnections campaigns) • Join our SBHRC or Love the Lea mailing list • Documents on RT forums • Build a network of RT members driving SuDS in UK • theo.thomas@thames21.org.uk
  19. 19. Evidence – Lamb Drove, Cambourne, Cambridgeshire County Council http://www.susdrain.org/case- studies/case_studies/lamb_drove_residential_suds_scheme_cambourne.html (Google search - Cambourne Lamb Drove SuDS Heavy metals – “We observed the greatest effects on several species of heptageniid mayflies (Ephemeroptera: Heptageniidae), which were highly sensitive to heavy metals and were reduced by >75% at moderately polluted stations.” HEAVY METALS STRUCTURE BENTHIC COMMUNITIES IN COLORADO MOUNTAIN STREAMS William H. Clements , Daren M. Carlisle , James M. Lazorchak and Philip C. Johnson.
