Greater transparency is needed on water quality modelling in the UK - written evidence to Environmental Audit Committee

11 minute read

Published:

The following was submitted by myself and Dr Gareth Roberts as written evidence to the Environmental Audit Committee’s non-inquiry session into water quality, published here. We highlight that computational tools being used by regulators and industry to divert billions of pounds of investment into are not transparent or readily accessible. We suggest that making software used to assess water quality open source is a crucial step towards developing trust in modelling results and consequent decisions.

A new approach to quantify the sources of pollutants (etc.) in rivers

How can we determine where a pollutant, and in what quantities, enters a river network? In two recently published papers my collaborators and I describe a new mathematical ‘inverse’ approach to solve this problem. We then use this technique to determine how chemicals such as illegal drugs and pesticides enter the River Wandle, a chalk stream in SW London, through both treated and untreated wastewater.
