DESCRIPTION (provided by applicant): This research endeavor has the broad goal to develop placement methods for in-situ sediment remediation amendments. Amendments will not be developed, but research is focused upon developing the water jet design and parameters to deliver amendments that have been proven at a bench-scale. Waterjet design and parameters developed herein will specifically result in efficiency and precision in amendment placement that will allow for efficient use of newly developed amendments, which are expensive, and likely foster the research into other amendments that were though to be too expensive or undeliverable. Waterjets placement methods are already shown to have lower resuspension and harmful impact to the benthic community, and a specific objective is to further develop methods, designs and procedures to minimize these detriments even further. This project will provide direct input for scale-up and transition to field-scale testing and implementation, with design and planning stages starting within this project schedule. RATIONALE: Remediation of contaminated sediments is not currently efficient with limited options, and the basic science developing currently has a focus upon remedial amendments, yet no deliver and placement method exists for efficient engineering utilization of these amendments. Waterjet placement can be applied for a suite of amendments targeting nearly all common sediment contaminants, specifically PCBs, PAHs and redox sensitive metals. RESEARCH DESIGN: Research design is will focus on optimizing design and operational parameters at escalating scales to meet the goal listed above and will result in a field-ready technology within the project period. The assembled team has extensive experience in scale-up of basic science discovery to very large, field-scale projects and technology development and even utilization. This range of experiences and expertise is unique and will certainly help in making success in this research endeavor highly likely. RELEVANCE TO PUBLIC HEALTH: Contaminated sediments are a substantial threat to human health, tainting the base layers of the food chain. Remediation expenditures are expected to reach well into the billions, yet only three options exist. None of which truly remediate the sediment. By increasing the efficiency and lowering the cost of remediating these sites, even more sites can be truly remediated.

描述（由申请人提供）： 这项研究努力的广泛目标是开发用于原位沉积物修复修正案的位置方法。修正案不会开发，但是研究的重点是开发水流设计和参数，以提供在台式规模上已证明的修订。本文开发的水夹设计和参数将特别导致修订放置的效率和准确性，这将有效利用新开发的修订，这些修正案很昂贵，并且很可能将研究促进了其他修正案，这些修正案却太昂贵或无法交付。水夹的放置方法已经显示出对底栖界的重悬和有害影响较低，并且一个具体的目标是进一步开发方法，设计和程序，以最大程度地减少这些损害。该项目将提供直接输入，以扩大和过渡到现场尺度测试和实施，并在此项目时间表内开始设计和计划阶段。基本原理：当前，对受污染沉积物的补救效果尚不有效，而发展的基础科学目前则关注补救修正案，但不存在用于对这些修正案的有效工程利用的交付和安置方法。可以将水夹放置用于针对几乎所有常见沉积物污染物，特别是PCB，PAH和氧化还原敏感金属的一系列修订。研究设计：研究设计将集中于在不断升级的尺度上优化设计和操作参数，以满足上述目标，并将在项目期间提供现场就绪的技术。组装团队在扩大基础科学发现扩展到非常大型的现场规模项目和技术开发甚至利用方面具有丰富的经验。这种经验和专业知识是独一无二的，一定有助于在这项研究中取得成功。与公共卫生有关：受污染的沉积物是对人类健康的重大威胁，构成了食物链的基础层。补救支出预计将达到数十亿美元，但只有三个选择。这些都没有真正补充沉积物。通过提高效率并降低修复这些站点的成本，可以真正修复更多的站点。
