NanoRem Project Bulletins

Posted: March 24, 2017

The Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment (NanoRem) project focused on facilitating practical, safe, economic, and exploitable nanotechnology for in situ remediation from 2013-2017. This project was undertaken in parallel with developing a comprehensive understanding of the environmental risk-benefit, market demand, overall sustainability, and stakeholder perceptions of the use of nanoparticles (NPs). Twelve NanoRem Bulletins have been created to transfer the knowledge developed within NanoRem to end-users.

Geospatial Analysis for Optimization at Environmental Sites

Posted: March 22, 2017

Geospatial analysis supports optimization activities throughout all stages of an environmental investigation or cleanup by improving performance of characterization and remediation activities, increasing monitoring efficiency, and justifying decisions. This Interstate Technology & Regulatory Council (ITRC) guide illustrates the practical application of geospatial analyses to support optimization activities and help practitioners apply geospatial analyses to their projects. This information will help state regulators and other practitioners to understand, evaluate, and make informed decisions about geospatial analyses for optimizing activities during environmental investigation or remediation. The material presented provides not only highly technical detail but also introductory information for those who may not have expertise in this area.

Best Practices for Environmental Site Management: Recommended Contents of a Groundwater Monitoring Report

Posted: March 22, 2017

The purpose of this issue paper is to recommend information to include in groundwater monitoring reports that will lead to improved report consistency and a useful, readable format. Incorporation of the recommended information will standardize groundwater monitoring report deliverables, which may in turn inform site characterization strategies, analysis of remedial alternatives, monitoring network optimization, remedy performance evaluation, continual refinement of the conceptual site model (CSM), and technical evaluation of groundwater data in five-year reviews.

In-Situ Capping of Contaminated Sediments

Posted: January 19, 2017

This publication was developed to serve as a basis for the design and assessment of remediation alternatives to dredging by providing a technology overview of various capping-based techniques and describing their possibilities and limitations. The guide consists of a main text (Section 30-1E) plus several supporting but stand-alone appendices: a preliminary review of contaminated sediments in Sweden (30-2E); a general overview of established ex situ and in situ sediment remediation technologies (30-3E); a preliminary overview of remedial sediment capping projects worldwide (30-4E); a short discussion on anticipated challenges with capping Sweden's fiberbank sediments (30-5E); an extensive bibliography of international technical references (30-6E); and an overall summary (30-7E).
