Abstract

While the Techniques and Technologies Associated with Contaminated Sediment Remediation Are Relatively Mature, There Are Several Issues Associated with These Practices that Make Them Unattractive. the Inability of Currently Used Mechanical Mixing Implements to Place Amendments in Aqueous Environments and their Intrusive Behavior toward Benthic Communities Are Just Two Examples of a Necessity for an Improved Delivery Method. Waterjets May Be a Viable Option for Placement of Particulate Remediation Amendments, Such as Activated Carbon and Granular Iron, at Depth. a Custom Waterjet Nozzle and Injection System Has Been Fabricated by the Authors to Examine This Delivery Concept. the Developed Injection System's Performance Was Tested by Characterizing the Waterjet-Delivered Amendment (Activated Carbon and Granular Iron) Distributions in a Surrogate Sediment. the Delivered Amendment Distributions Followed Similar Patterns for a Range of Injection Times and a Variety of Amendments. the Injection Depths, However, Were Dependent Upon the Type of Amendment Being Injected. These Findings Have Led to a Better Understanding of What Occurs during an Amendment Injection, Which Can Be Used for a More Controlled Placement of Remediation Amendments using This Technique in the Future. the Laboratory Results Indicate that the Subject Waterjet System May Have the Potential for Field-Scale Applications, Especially for Granular Iron Delivery, as the Authors Were Able to Place between 60 and 70 Wt Percent into a Surrogate Sediment Bed Along the Path of Injection. © 2011 Wiley Periodicals, Inc.
