"This is public health we're talking about! So where's your evidence ...

or, at least your planned monitoring rationale, 
structure, processes and 
projected reporting schedule?"

measures - metrics river health 'There is a chance that results will get better over time. Leon Barron, professor of environmental science at Imperial College London, said water quality metrics could lag behind and needed to be taken over multiple seasons and years to get an accurate reading.' 1,3,5,10 ... years? What is local? What is national?

public health  'Amy Fairman, head of campaigns at environmental charity River Action, called the independent pollution figures "deeply shocking" and demanded that Tideway publish its internal data in full. "The public deserves to know, given they are paying for this tunnel through their water bills, that it is actually delivering improvements," Fairman said.'

'Tideway argued that assessing water quality trends required multiyear data-sets and that a single year of observation "would not provide a sufficiently robust picture". "The Thames is a complex tidal river, and water quality is influenced by a range of factors beyond the combined sewer overflows that Tideway was designed to address," it added. "Individual E. coli readings can fluctuate depending on location, rainfall, tides and other inputs. These readings cannot, in isolation, provide a complete picture of the tunnel's impact."

Windermere will be a different story then?
