Developing a high resolution site characterization method for contaminated marine sediments

SCG工业为陆上受污染的**场地提供环境场地评估和补救服务。该公司已经为这些地点开发了现场评估工具，使补救工作能够以**高效和具有成本效益的方式进行。水下的海洋污染场地给场地评估带来了不同的挑战。在河口和港口**疏浚和处置受污染的沉积物是一笔巨大的费用。为了确保适当的清理，大片区域的疏浚是根据现场**评估(即昂贵的水基钻探)进行的，不幸的是，这也导致了少量**样本。然后，保守地制定疏浚计划以涵盖这一不确定的数据集，并由于必要的不确定性而产生更多**疏浚容量(即更高的处置成本)。目前，还没有**流行的场地表征技术用于解决这个问题。**SCG已经确定了一种新的海洋环境表征技术的潜力。有了这一**能力，SCG将在本地和国际市场上更具竞争力，并将在希望降低疏浚成本的客户中打开**新市场。SCG将与Dalhousie**大学和研究小组对海洋污染沉积物的知识合作，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，一个实地地点将用于开发该方法并为该方法**提供概念证明。该项目将涉及实验室和实地工作，以支持开发用于实时检测海洋沉积物污染的新的**数据过滤方法。发展这项技术的根本挑战是确保**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。将使用几个HRSC**工具来探索从各种数据过滤技术获得的不同程度的敏感性。

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.
