The accessibility of safe drinking water supplies is centrally linked to public health, well-being and economic prosperity globally. Chemical hazards, such as arsenic, fluoride and emerging organic contaminants, which may be present in groundwater due to natural and/or anthropogenic processes, can threaten the safety of drinking water supplies.Remediation, or treatment, of water can be undertaken, prior to water consumption, using a variety of technologies to reduce exposures to chemical and microbial contaminants which may be present. However, effective implementation of remediation approaches can be challenging, particularly in areas where centralized, treated, piped water supplies are not available or accessible.The optimal selection and management of appropriate remediation approaches can be challenging because of variability in the suitability of different types of remediation technologies, as well as variability in geochemical conditions, socio-economic and regulatory context, risk trade-offs and gaps in the availability of data relevant for decision-support (e.g. remediation efficiency testing, local geochemical conditions). The aim of the GeoCERT project is to help address some of these challenges by establishing the relationship between the efficiency of market-available groundwater remediation technologies and source water chemistry to help support optimal selection of remediation strategies in the context of South Asia. Building on from our recent and ongoing research in Bihar, and working closely with Project Partners at Mahavir Cancer Sansthan (Patna, India) and University of Melbourne (Melbourne, Australia), we will systematically address this aim by investigating the performance of market-available remediation technologies for the removal of arsenic, fluoride and an example emerging organic contaminant (sucralose) in groundwaters representing the range of compositions found in Bihar, India. With an underpinning focus on knowledge exchange and impact, we will work closely with our partners to produce catalytic outputs including leading publications reporting key findings, stakeholder guidance and submission of further proposals to develop robust, data-informed decision support systems for groundwater remediation in South Asia and elsewhere in the Global South.

安全饮用水供应的可获得性与全球公共卫生、福祉和经济繁荣密切相关。由于自然和/或人为过程，地下水中可能存在砷、氟和新出现的有机污染物等化学危害，这些化学危害可能威胁饮用水供应的安全。在用水之前，可以利用各种技术对水进行补救或处理，以减少可能存在的化学和微生物污染物的暴露。然而，补救办法的有效实施可能具有挑战性，特别是在没有或无法获得集中式、经处理的管道供水的地区，由于不同类型的补救技术的适用性不同，以及地球化学条件、社会经济和监管环境也不同，风险权衡和与决策支持相关的数据可用性方面的差距（例如，补救效率测试、当地地球化学条件）。GeoCERT项目的目的是通过建立市场上可用的地下水补救技术的效率与水源水化学之间的关系，帮助解决其中一些挑战，以帮助支持南亚背景下的补救战略的最佳选择。基于我们在比哈尔邦最近和正在进行的研究，并与Mauryr Cancer Sansthan的项目合作伙伴密切合作（印度巴特那）和墨尔本大学（墨尔本，澳大利亚），我们将系统地解决这一目标，通过调查市场上可用的砷去除修复技术的性能，氟化物和代表在印度比哈尔邦发现的组成范围的地下水中出现的有机污染物（三氯蔗糖）的实例。以知识交流和影响为基础，我们将与合作伙伴密切合作，产生催化性成果，包括报告主要发现的领先出版物，利益相关者指导和提交进一步的建议，以开发强大的，数据知情的决策支持系统，用于南亚和全球南部的地下水修复。
