Together towards a pollution-free aquatic environment

Lead Research Organisation: UNIVERSITY OF YORK
Department Name: Environment

Abstract

Brief-Summary:

Our partnership of 24 public, academic, government, charity, and business groups comprising 1709 members of the public address Yorkshire's aquatic pollution problem. Utilising the citizen science toolkit we co-produced, we will investigate six co-produced research questions and help prioritise upcoming investments in real-world, data-driven environmental solutions. Our inclusive/diverse community of practice will benefit national aquatic monitoring capacity and leave behind a legacy of accurate citizen science methodologies, build public capacity, and foster environmental leadership.



Details:

After centuries of manipulation and neglect, Yorkshire's rivers and lakes have a pollution problem involving a cocktail of anthropogenic chemicals and microbial contaminants.[1] Of the 982 regional water bodies, none currently achieve a high ecological or chemical status.[1][2]These are places of valued biodiversity, public health benefit, and resources from which we extract our drinking water.[3] Healthy aquatic environments positively impact both ecological and human health, as evidenced by surveys we conducted (n=152 responses) showing Yorkshire's public appreciation for social, recreational, spiritual, and mental health activities near water. However, increasing aquatic pollution hinders ecological health and public use of water bodies, jeopardising biodiversity and the positive benefits these environments foster in our communities.[4][5] This is exacerbated by recent reductions in funding for Environment Agency monitoring,[6] highlighting an urgent need for innovative approaches to environmental monitoring/management amid growing public outrage.[7]

We aim to create an inclusive and diverse Yorkshire community of practice using techniques new to citizen science that builds monitoring capacity and moves us towards achieving a non-toxic aquatic environment benefiting biodiversity and people. We co-developed six priority questions based on public concerns which form the basis of our proposed research. These questions not only cover the state of Yorkshire's aquatic environment and how it can be improved, but also how the process of aquatic citizen science can be made more trustworthy, inclusive, and sustainable. We already co-produced and trialled a novel citizen science toolkit of harmonised methodologies that goes beyond traditional citizen science determinants (e.g., nitrate, pH) to include priority micropollutants (e.g., pharmaceuticals, perfluorinated compounds) and bacterial species (e.g., faecal coliforms). The toolkit will underpin data generation across nine case-study waterbodies via approaches we successfully co-developed during the bursary stage.

By equipping the public with an accurate and easy-to-use environmental monitoring toolkit we can surpass the limited spatiotemporal capacity of academic and regulatory environmental monitoring. This will create a step-change in the data available to understand environmental pollution and we will use the this to quantify where and how environmental solutions can best mitigate the problem. These solutions will be nature-based (e.g., constructed wetlands), infrastructural (e.g., improvements to leaky combined sewage overflows), stewardship-based (e.g., working with farmers to reduce agricultural runoff), and community-based (e.g., unifying/elevating the public voice to lobby for change). Ensuring and verifying quality, we aim to create a paradigm shift that increases the value of citizen science data and opens the door for incorporation into already-stressed regulatory monitoring schemes.

PI Contribution The project team at the University of York developed a novel citizen science test which quantifies levels of E. coli in river water which is cheap, easy to do and does not require electricity. Until this collaboration with the Environment Agency, the accuracy relative to 'gold standard' regulatory E coli tests was unknown. Hence, its potential use in regulation or EA applicability was also not established. Here we partnered with the EA to evaluate the accuracy and robustness of this novel tool. We carried out real world paired sample analysis to determine that the novel test produced data which is not statistically significant to the results from the same samples produced in EA laboratories. This opened the door to uptake of citizen science data use and by-in from regulators and stakeholders alike.
Collaborator Contribution The Environment Agency analysed paired samples (i.e., the novel Citizen Science test and EA tests were using aliquots of the same water sample) using their 'gold standard' method for quantifying E. coli within EA laboratories. The data from this analysis was supplied to the project team at the University of York who then compared the results. This allowed a direct comparison between the results from the novel citizen science test and regulatory tests for E coli for the first time.
Impact The results have been presented to the Environment Agency, citizen science groups and at at least one scientific meeting (hosted by UNESCO) in Feb 2026. A publication is pending and is expected to be published in 2026.

Results and Impact On 2 December 2025 a colleague and I (John Wilkinson) travelled to the Leamington Spa Library and Information Centre which also houses a local museum. The museum received funding from the Natural History Museum to conduct outreach activities engaging with a wide audience with the aim of creating a new exhibition that linked to themes brought up in discussion sessions. We were invited to share our citizen science research on water contamination with school kids (6th form) which was followed by actually doing some citizen science on a local river then discussion of items in the museum's collection for inclusion in the upcoming special exhibition.
