  • 1. Managing Point sources – Experiences from the TOPPS project Train Operators to Prevent Point Sources Brussels 23rd March 2010 Manfred Roettele TOPPS Project Manager BetterDecisions
  • 2. Outline •About TOPPS • Focus on infrastructure • EU context • Remnant management the forgotten risk • Point sources what is it • Outlook • Key risk areas •Focus on correct behaviour •Focus on improved equipment
  • 3. TOPPS – PROJECT – Funded by EU- LIFE and ECPA Objectives: FI SE •Common BMPs DK (stewardship+risk mitigation) H UK NL • Training / Demonstration materials BE TOPPS PL CZ DE FR • Dissemination of BMPs SK IT • Proposal for a sustainable strategy to avoid point FR ES sources PT www. 15 countries / 18 cooperators TOPPS started Nov 2005 and ended Oct 2008
  • 4. Agriculture is considered a major pollutor of water Nitrogen Phoshate Pesticide, (PPP) DG - Environment
  • 5. Legal initiatives and agriculture support policies are connected Nitrates directive – in Nitrate Vulnerable Zones Water Framework CAP Cross Directive– Measures operational by October 2012 ? compliance GAEC to be introduced by 2012. Good status 2015 Pesticides Framework Directive Objectives to be set up in National Action Plans.
  • 6. Main entry routes of Plant Protection Products (PPP) into surface water are : point and diffuse sources Point sources Run-off Drift Drainage
  • 7. POINT SOURCES were not sufficiently in the focus Method of point sources measurement - Univ Giessen) Univ Giessen) Few studies distinguish Catchment area between point and diffuse sources (D, B, UK) Village with farms Sewage plant Measurement 2 Measurement 1 Diffuse source Point source Presented by Prof. Frede Univ.Giessen at TOPPS Forum Germany Oct 2006 (changed)
  • 8. SIGNIFICANCE OF POINT SOURCES Point sources are the main route of suface water contamination 5 Catchment areas in Hessen/Germany from 33 35 25 5 23 diffuse sources from Point sources 67 65 75 95 77 area 1900 km² 25km² 20km² 7 km² 50 km² POINT SOURCES CONTRIBUTE > 50 % Presented by Prof. Frede Univ. Giessen at TOPPS Forum Germany Oct 2006 (changed)
  • 9. SIGNIFICANCE OF POINT SOURCES Reduced PPP in surface water after intensive training and transfer of sprayer cleaning to the field .- Study: Univ. Giessen Hessen /Germany Wölfersheim of PPPOrtschaften/Kläranlagen insewage plants Rel. reduction 4 pollution in 5 catchments Hessen (Wetterau) A B C D -82% -70% -61% -69% -80% The cleaning process of the sprayer transfered to the field is able to reduce the point source pollution by about 70% Presented by Prof. Frede Univ. Giessen at TOPPS Forum Germany Oct 2006 (changed)
  • 10. Key risk area filling 10
  • 11. Bad empty container management 11
  • 12. Sprayer cleaning close to surface water 12
  • 13. Bad residual volumes / remnants management 13
  • 14. Managing Point sources Key risk areas • Cleaning Correct • Remnant Management Behaviour • Filling Improved Improved Equipment Infrastructure Transport Storage Before spraying During spraying After spraying Remnant management
  • 15. Best Management Practices (BMPs) •what to do and how to do things (practical) CORRECT BEHAVIOUR • defined along the work processes (complete) • European core , local adaption (credible) • BMPs on water protection were not in all countries available, often to general • mismatch between rules / regulations and the translation what it means in practise (who knows what 0,1 µ/l means in practise ???)
  • 16. ... Key is to change behaviour BMPs Correct development Behaviour Key dimensions support behaviour change BMPs BMPs TOPPS - KEY MESSAGES transfer implementation •Develop training modules for Advisers and utilize all advice capacities (Certified, documented, private + public advisors: Example BASIS?) •Create a market for agro - environmental advice •Offer operator training modules on water protection (voluntary/mandatory) (Certified, documented, apply audit tools. Example: Aquasite Arvalis?) •Define water protection targets, control processes and measure progress
  • 17. Equipment and infrastructure are key enablers to mitigate point source risks Improved Equipment Improved Big improvements were made in Infrastructure application techniques • Environmental aspects „regulated“ by EN / ISO Standards • Environmentally optimized sprayers need to compete in the market with lower level sprayers (tough sales today !) ...... the TURBO is in but the CATALYST is often missing Picture Harald Kramer LWK_NRW
  • 18. Reduce Residual volumes Best sprayers today have 50% less residual volume compared with the requirements of the standard How can we help environmentally optimized sprayers to compete better ? Who knows ? Who talks about it? Current standards for Fieldsprayers Total residual volume in l (EN 12761-2) If the cleaning is Tank Boom not done properly Tank volume 0, 5 % length m 2l / m Total litres some of these 800 4 15 30 34 residual volumes 3000 15 21 42 57 may end up in the 4200 21 36 72 93 water Arable Farmers clean their sprayers 7 to 10 times / season* *TOPPS farmer surveys
  • 19. Improved rinsing – altenative Procedure Continuous rinsing offers more convenience, faster, less water TOPPS explored continuous rinsing (TOPPS-clean alternativ method) ...needs additional pump, but more convenient, faster, less water Cost to upgrade sprayers 600 to 1500.- € Continuous rinsing compared to triple rinsing procedure under practical conditions (Fieldsprayer: 12 m boom, Airmix 03 nozzles (output 20 l/min), spray pressure 1,5 bar. Dilution % was measured photo- metric by using fluorescent tracer * Amount of water Time needed Dilution rate achieved Triple rinsing 3 x 30 (90 l) 30 minutes 0,2 % Continuous rinsing 40 l 4 minutes 0,3 % *H. Kramer, LWK-NRW 2009
  • 20. Risk area outside cleaning 20
  • 21. Outside cleaning is a challenge especially for air assisted sprayers Research in BE and IT show significance of outside cleaning of orchard sprayers At application of 25 kg ai / year about 82,5 to 207 g ai / ha deposits were measured on the sprayer (Assumption: 20 ha means about 1650 bis 4140 gai – Debear 2006) Recommendation: Outside cleaning in the field, while deposits are still wet
  • 22. 22
  • 23. Example: Infrastructure > 85% of farmers fill and wash their sprayers on farm Precautionary Improved measures Equipment necessary if filling , cleaning done on hardsurfaces Improved Biopurification Infrastructure systems Biobed, Biofilter to treat diluted contaminated washing waters
  • 24. What to do with the PPP contaminated liquid which still stay in the sprayer or washing water (Remnant management) EU context Country Officially recommended procedure FRA If residual volume is diluted to 1%, residual volume can remain in the field (only very little will return to farm) DK If residual volume is diluted to 2% residual volume can remain in the field BE*, UK, Biobed, Biofilter (Bioremediation) approved methods FR, SE (*Wallonia) DK, DE* Collection in Slurry and spreading with slurry in field (*NRW) NL ? Operators left alone in many countries with remnants management
  • 25. Outlook ECPA – Water protection projects landscape Mitigation of Point sources 15 EU countries Bridge Mitigation AIM Diffuse sources PROWADIS -Life ? 22 EU countries Oct 2005 Nov 2008 Sept 2010 Oct 2013 Efficient multistakeholder risk mitigation is the target
  • 26. Mitigation of PPP water contamination needs to be managed as a multistakeholder challenge Farmer / Operator Improved Improved Equipment Infrastructure Research practical Regulations PPP Monitoring / consistent Inspection Best Management Standards Support Legislation Practice – Advice enforced comprehensive Public opinion Politics Media Society (regional, national , EU
  • 27. IMPLEMENTATION REMAINS THE CHALLENGE ! Thanks for your attention Acknowledgement for support to Life, ECPA, the TOPPS partners and many supportive stakeholders Right focus, strategy and support will help to develop a consistent approach to protect water STAY ON TOPPS –
