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.

SCG Industries为陆地污染 ** 场地提供环境场地评估和补救服务。该公司为这些场地开发了场地评估工具，使补救工作能够以高效和具有成本效益的方式进行。100.在水下的海洋污染场址对场址评估提出了不同的挑战。在河口和港口 ** 疏浚和处置受污染沉积物的费用很高。为了确保适当的清理，根据现场 ** 评估（即昂贵的水基钻井）进行大面积疏浚，不幸的是，这也会导致少量 ** 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，由于必要的不确定性，产生了增加的 ** 疏浚量（即更高的处置成本）。目前，没有 ** 普遍的网站特性技术用于此问题。** SCG已经确定了海洋环境新特征描述技术的潜力。有了这种能力，SCG将在本地和国际市场上更具竞争力，并将在希望降低疏浚成本的客户中开辟新的市场。SCG将与达尔豪西 ** 大学和研究小组的海洋污染沉积物的知识合作，开发一种新的高 ** 分辨率现场表征（HRSC）技术，用于这一应用。鉴于这项工作代表了一种新方法的开发，一个现场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，以支持开发新的数据过滤方法，用于检测海洋沉积物的实时污染。该技术开发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。将使用几种HRSC** 工具来探索从各种数据过滤技术中获得的不同灵敏度水平。
