Endocrine-disrupting chemicals (EDCs) affect the hormone systems of animals, mimicking the effects of naturally occurring hormones (such as oestrogen or testosterone) in animals and blocking their action. The effects of these chemicals are wide-ranging and include reproductive failure and developmental problems. Unfortunately, a huge variety of compounds have the potential to disrupt the endocrine system, including pharmaceuticals (e.g. antibiotics), personal care products (e.g. deodorants) and raw materials for manufacturing (e.g. bisphenols). While the full effect of these compounds on human health is not yet known, their removal from drinking water is an emerging problem in water treatment, and one that only becomes more important as more EDCs are discovered. The best way to remove a given EDC from drinking water is not always obvious, and the standard practice is to screen different possible methods to find the optimum. This can be very costly in terms of both money and time, and the method that is best for one source of drinking water may not always be best in another source whose composition is different. This project harnesses the power of computational chemistry and machine-learning (ML) to speed up the search for materials for EDC removal, beginning with atomistic simulations to study water decontamination in silico, in tandem with the results of laboratory experiments. The culmination of this work will be the development of an efficient and robust ML framework that can predict the ability of a material to remove an endocrine disruptor from drinking water, saving a significant amount of experimental time by suggesting candidate materials to focus on, and allowing the water management industry to act quickly to deal with newly discovered EDCs.

Partners: Environment Agency, Canal & River Trust, Northern Ireland Water/Aecom, RSK Challenge: Our partners collectively own over 10,000km of water retaining earthworks (embankments/dams), which protect large areas of the UK from flooding. Recent effects of extreme weather on UK earthworks have highlighted their vulnerability to climate change with numerous failures reported across a range of infrastructure networks. Given that climatic variations are projected to become more extreme, developing and maintaining resilient infrastructure is essential to our partners and all UK geotechnical asset owners. Early identification of poor/deteriorating earthwork condition is essential for cost effective maintenance and prevention of hazardous and expensive failures. Current earthwork condition assessment practice is, however, usually based on visual observations with little/no information available on their underlying internal condition. This project will demonstrate an innovative geophysical approach, using seismic surface waves (SW), for non-invasively assessing internal earthwork condition, while also adapting the outputs to ensure compatibility with our partner's management systems. This approach will support asset management decisions, including, for example, maintenance prioritisation; selection/configuration of monitoring works and selection/targeting of interventions. The speed of SW data acquisition, high spatial coverage and relative low-cost of these measurements will remove key barriers to preventative management. Aims/Objectives: This project aims to translate the findings from a recent EPSRC project "GEOCARE" to asset owners/managers of water retaining earthworks that protect the UK from flooding. The objectives (O) and supporting activities (A) are: O) Demonstrate an innovative approach for assessing internal earthwork condition. A) SW data will be acquired at selected partner sites and will be used to derive 2D/3D asset condition models. O) Adapt this technology to ensure compatibility with our partners' management systems. A) Project staff will be seconded to each partner organisation for short periods in order to better understand their condition assessment practices, databases, and to optimise survey outputs to their requirements. Regular stakeholder meetings with our partners' will also ensure that scientific, engineering and information delivery developments are appropriate. O) Permanently embed this knowledge and capability within our project partners. A) In addition to secondments and stakeholder meetings, guidelines on the integration of SW into asset ranking, prioritisation and intervention planning will be written. O) Widely disseminate the project's technological outcomes. A) A workshop will be organised to showcase the project's technological outcomes to a wide audience. Results and recommendations will be further disseminated through a project website, articles in industry magazines and via a case study with CIRIA. Main Deliverables: 2D/3D voxelated condition models will be developed for each partner's site, to showcase SW technology (D1). This will enable early informed decisions on maintenance and remediation to be made, thereby removing a barrier to preventative management. These models will be integrated within our partner's management systems (D2) following consultation and secondments at each organisation. Guidelines on the use of SW outputs in condition assessment practice (D3) will be developed for each partner to further embed the knowledge. A workshop will be organised to showcase the project's technological outcomes and benefits to proactive asset management to a wide stakeholder audience (D4). Results and recommendations will be further disseminated through a project website (D5), articles in industry magazines (D6) and via publication of a case study with CIRIA (D7).

The EPSRC Centre for Doctoral Training in Water Infrastructure & Resilience II (WIRe II) builds upon the highly successful collaboration between three of the UK's centres of excellence in water research (Cranfield, Sheffield and Newcastle Universities). One of the foundations of a thriving civic community and economy is having secure, resilient and sustainable water resources and services that: (i) provide affordable and equitable access to water; (ii) deliver a safe drinking water supply; (iii) provide wastewater services that don't pollute the environment; (iv) ensure there is enough water to meet the increasing demands from multiple sectors; and (v) are net beneficial to the environment, while protecting critical infrastructure from the impacts of climate change. This is placed against a backdrop of increased levels of dissatisfaction and higher expectations from civic communities on their water services, multiple demands on water resources and adaptations required from the impacts of climate change. With the UK population expected to grow from 69 million to 79 million by 2050, water resources have never been under as much pressure. Recent assessments have shown that only 14% of English rivers have good ecological status and no river has good chemical status. Water companies have also been placed under significant public examination from recent well-publicised pollution incidents from storm overflows and restrictions in water, with expectations that the UK will need to save 4billion litres of water per day by 2050. A collaborative and interdisciplinary approach is therefore essential for securing more resilient and sustainable water systems. There is also an urgent demand for improved water management as we move into a more sustainable world - the requirement for suitably skilled specialists with the appropriate interdisciplinary skills has never been higher. In developing the case for WIRe II, we have brought together an important group of civic partners, including the water utilities (with representation from all nations of the UK, covering water and wastewater services for 90% of the UKs population), organisations from the energy sector working on net zero technologies that have significant water demand and/or wastewater streams, regulators and civic groups, consultancies who work across the water-energy nexus, and partnerships with UKCRIC and DAFNI for access to world leading facilities. The CDT will be a significant contributor to addressing a clear skills gap identified by our partners and provide a future blueprint for enhanced training in the sector. We urgently need research to understand whole water systems (catchment, treatment and distribution processes) to achieve stable, safe water delivery to customers and the return of water back to the environment for multiple beneficial purposes. Such complexity requires inter- and trans-disciplinary research and a critical mass of experts and outputs. Three interconnected research themes will be addressed in WIRe II that align with key civic priorities: Safe and sustainable water resources for all; A resource neutral water sector; and Adapting to climate change. The WIRe II training programme has been developed with our partners to ensure we develop talent with the skills, competencies, and creativeness required to meet the changing demands of the sector. Built around the principles of deep vertical and horizontal integration of cohorts, students will progress through the CDT by undertaking a common induction semester, an assessed taught programme, an inspiring transferable skills curriculum and an annual Summer Challenge, alongside opportunities for national and international placements. We have evolved the programme to deliver the transformative science needed to tackle the rapidly changing demands and challenges being faced across our water systems and to develop the future leaders in the water and allied sectors.
