Totally Thames Water-Blitz
![Page 2: CaBALondon 06 Hilary Philips, Wild Oxfordshire](https://reader036.fdocuments.us/reader036/viewer/2022070514/587de52f1a28abaf6b8b64b7/html5/thumbnails/2.jpg)
What?•1,000 water samples from a single day•All using the same test kits supplied by River Thame Conservation Trust
•Tested by FHT for Earthwatch•Calibrated against CEH lab-tested results•Mapped by Earthwatch on Fresh Water Watch site
![Page 3: CaBALondon 06 Hilary Philips, Wild Oxfordshire](https://reader036.fdocuments.us/reader036/viewer/2022070514/587de52f1a28abaf6b8b64b7/html5/thumbnails/3.jpg)
Why?•Highlight importance of Thames River Basin to London-focused Totally Thames Festival
•Engagement opportunity for catchment groups• Impetus for other organisations to join forces•Provide data for catchment partnerships & EA to use in combination with Historic / lab data
![Page 4: CaBALondon 06 Hilary Philips, Wild Oxfordshire](https://reader036.fdocuments.us/reader036/viewer/2022070514/587de52f1a28abaf6b8b64b7/html5/thumbnails/4.jpg)
Why?•Highlight areas which are likely to be most important for freshwater biodiversity
•Provide a focus for positive achievable action by citizen-based groups or individuals
•Focus attention on places where we can have the greatest beneficial impact – protecting what is already good. (FHT ‘Clean Water for Wildlife’)

Green dots give us information on where we need to protect our least nutrient impacted and possibly best freshwater biodiversity sites
Orange dots give us a guide to locations where some interventions to reduce nutrient input may be able to get them low enough to have some ecological benefit.
Red dots are highly impacted and have been for a long time in the Thames (nitrate records available on the Thames from 1850’s) and would need major costly interventions on a huge scale to get low enough to see eco benefits.

EA - Phosphates standards and the WFD
New standards for the second cycle RBMPs Improved relationship between water quality and biology Based on river type (alkalinity & altitude) New standards for Good status: Median and (Range of concentrations)

• Clean Water for Wildlife: national project assessing nutrients in streams, rivers, ponds, lakes, ditches, springs
• PondNet: a new national volunteer network for ponds (includes eDNA national survey for great crested newts)
• Thames-specific component with £80k sub-project newly funded by Thames Water Ltd (includes nutrient testing)
2. Developing catchment based water quality assessment with volunteers
• 3 year, c£150k, Earthwatch-funded project usingnutrients kits to assess ponds, streams, rivers
• Detailed rapid kit user manual due Nov 2015
