Developing a high resolution site characterization method for contaminated marine sediments

SCG Industries为受陆地污染的**场所提供环境现场评估和修复服务。公司为这些站点开发了现场评估工具，使修复工作以高效和经济的方式进行。水下的海洋污染场地对场地评估提出了不同的挑战。在河口和港口疏浚和处置受污染的沉积物**是一项巨大的成本。为了确保适当的清理，大面积的疏浚工作是根据现场评估（即昂贵的水基钻探）进行的，不幸的是，这也导致了少量的样本。疏浚计划然后保守地制定，以涵盖这个不确定的数据集，并增加疏浚体积（即更高的处置成本），由于必要的不确定性产生。目前，没有**流行的位点表征技术用于这个问题。**SCG已经确定了一种新的海洋环境表征技术的潜力。有了这种能力，SCG将在本地和国际市场上更具竞争力，并将为希望降低疏浚成本的客户打开新的市场。SCG将与Dalhousie**大学和研究团队的海洋污染沉积物知识合作，为这一应用开发一种新的高分辨率现场表征（HRSC）技术。鉴于这项工作代表了一种新方法的发展，一个现场将用于发展该方法并为该方法提供概念证明。该项目将包括实验室和实地工作，以支持开发用于实时检测海洋沉积物污染的新型数据过滤方法。开发该技术的潜在挑战是确保研究人员和SCG能够开发适当的数据过滤技术，以确保表征技术具有足够的检测能力。几个HRSC**工具将用于探索从各种数据过滤技术获得的不同级别的灵敏度。

SCG Industries provides environmental site assessments and remediation services for land-based contaminated**sites. The company has developed site assessment tools for these sites that allow remediation to proceed in an**efficient and cost-effective manner. Marine-based contaminated sites, under water, represent different**challenges to site assessment. Dredging and disposal of contaminated sediments in estuaries and harbours**represent a significant cost. To ensure proper cleanup, dredging of large areas is performed based on site**assessments (i.e. expensive water-based drilling) which also unfortunately results in a small number of**samples. Dredging plans are then conservatively developed to encompass this uncertain dataset and increased**dredge volumes (i.e. higher disposal costs) are generated due to necessary uncertainty. Currently, there is no**prevalent site characterization technique used for this problem.**SCG has identified the potential for a new characterization technique for marine environments. With this**capability, SCG will be more competitive in the marketplace, both locally and internationally and will open**new markets among customers wanting to reduce dredging costs. SCG will collaborate with Dalhousie**University and the research team's knowledge of marine contaminated sediment to develop a new High**Resolution Site Characterization (HRSC) technique for this application. Given this work represents the**development of a novel method, one field site will serve to develop the method and provide proof of concept**for this method. The project will involve laboratory and field work to support the development of the novel**data filtering method for detecting real-time contamination of marine sediments. The underlying challenge to**development of this technique is ensure that an appropriate data filtering technique can be developed by the**researchers and SCG to ensure adequate detection capability of the characterization technique. Several HRSC**tools will be used to explore different levels of sensitivity obtained from the various data filtering techniques.
