项目摘要

Groundwater is a hugely important natural resource, providing the majority of drinking water globally, some 35% of drinking water in the UK, and up to 80% in southern England. High frequency real-time systems are now widely used in water industry for water quality monitoring, however transient microbiological contamination is currently still monitored using traditional spot sampling and culturing techniques. The highly dynamic nature of microbiological contamination necessitates high frequency on-line monitoring for the optimisation of down-stream processes such as treatment and distribution. We propose to pilot and embed within the UK water industry the use of new fluorescence sensors to enable this. In addition, while it is generally understood that high levels of faecal contamination in groundwater may be accompanied by relatively high turbidity, this is often not the case, and depends on the source and pathway of faecal contamination in the subsurface. Differentiation of turbidity derived from aquifer material or induced by pumping and that derived from microbial contaminants has significant potential benefits to the water industry through treatment process optimisation. Water companies in England and Wales have invested £42 million on investigations into source water characterisation and treatment process optimisation from 2010 - 2015 (OFWAT 2009) but understanding transient microbial contamination remains a significant challenge. Recent NERC funded research on in-situ fluorescence spectroscopy, now a well-established technology, offers a highly sensitive method to achieve this for raw groundwater sources. Through a partner led process we have developed a proposal to pilot, embed and develop an implementation strategy for this technology that is relevant for the UK water industry, but is also highly relevant for international water and health sector organisations. As part of this proposal, placement activities within two UK water companies (Affinity Water and Wessex Water) will be carried out to i) pilot and embed the use of tryptophan sensor technology in the UK water industry for improved monitoring of microbiological contamination in vulnerable groundwater sources, ii) provide robust evidence on the suitability of the current turbidity trigger (1NTU) for groundwater quality assessments, iii) provide an implementation strategy for this technology within the UK water sector through user-led collaboration. This will be carried out though visits to all UK water companies to obtain feedback on how this could benefit and be implemented in different parts of the water sector and disseminate findings with potential new end users.Working with key partners from across the UK water industry, including water companies (Affinity Water and Wessex Water) and cross-sector organisations (UKWIR, Water UK and DWI), TryGGER aims to embed within the UK water sector the use of on-line sensors for monitoring dynamic microbiological contamination in groundwater sources for improved use of water resources and optimisation of treatment processes. The application of this sensor technology will be piloted in four case study sites in the UK, through placement activities undertaken by BGS scientist in water industry partners. These have been selected in consultation with water utilities to be representative of vulnerable groundwater settings, with wide applicability both within the UK context and globally. Importantly, a strategy for implementing the use of these sensors for raw water quality monitoring will be developed with end users from across the UK water industry as part of this proposal to enhance wider uptake of this technology. This proposal has the potential for far reaching impact in the UK water industry and further afield. Involvement of the main players in the water industry, as well as utility firms, from early on during proposal development this has ensured that is highly relevant to the end-user community.

地下水是一种非常重要的自然资源，提供了全球大部分的饮用水，约占英国饮用水的35%，在英格兰南部高达80%。高频实时监测系统已广泛应用于自来水行业的水质监测，但目前对瞬时微生物污染的监测仍采用传统的现场采样和培养技术。微生物污染的高度动态性需要高频在线监测，以优化下游过程，如处理和分配。我们建议在英国水务行业试点并嵌入新型荧光传感器，以实现这一目标。此外，虽然人们普遍认为，地下水中的高水平粪便污染可能伴随着相对较高的浑浊度，但事实往往并非如此，这取决于地下粪便污染的来源和途径。通过优化处理过程，对含水层物质或泵送引起的浊度和微生物污染物产生的浊度进行区分，对水工业具有重大的潜在好处。从2010年到2015年，英格兰和威尔士的水公司已经投资了4200万英镑用于调查水源特征和处理过程优化（OFWAT 2009），但了解瞬时微生物污染仍然是一个重大挑战。最近NERC资助的原位荧光光谱研究，现在是一项成熟的技术，提供了一种高灵敏度的方法来实现原始地下水资源。通过合作伙伴主导的过程，我们已经制定了一项提案，以试点、嵌入和制定这项技术的实施战略，这不仅与英国水务行业相关，而且与国际水务和卫生部门组织也高度相关。作为该提案的一部分，将在两家英国水务公司（Affinity water和Wessex water）内开展安置活动，以i)在英国水务行业试点并嵌入色氨酸传感器技术的使用，以改进对脆弱地下水资源微生物污染的监测，ii)为当前浊度触发器（1NTU）对地下水质量评估的适用性提供强有力的证据。iii)通过用户主导的合作，为英国水务部门提供该技术的实施策略。这项工作将通过访问英国所有的水务公司来进行，以获得反馈意见，了解如何在水务部门的不同部门实施这一措施，并将调查结果传播给潜在的新最终用户。TryGGER与来自英国水务行业的主要合作伙伴合作，包括水务公司（Affinity water和Wessex water）和跨部门组织（UKWIR， water UK和DWI），旨在将在线传感器嵌入英国水务部门，用于监测地下水资源中的动态微生物污染，以改善水资源的利用和优化处理过程。这种传感器技术的应用将在英国的四个案例研究地点进行试点，由英国地质调查局的科学家在水务行业合作伙伴中开展安置活动。这些都是在与水务公司协商后选择的，作为脆弱地下水环境的代表，在英国和全球范围内都具有广泛的适用性。重要的是，将与英国水务行业的最终用户一起制定实施这些传感器用于原水质量监测的战略，作为该提案的一部分，以加强该技术的广泛采用。该提案有可能对英国水务行业产生深远的影响。水务行业的主要参与者以及公用事业公司从提案制定的早期就参与进来，这确保了它与最终用户社区高度相关。
