(QCMR-1)

This web-based guidance document presents quality considerations for munitions response (MR) projects. The document explains the decision logic used for an MR project and offers resources for planning and monitoring quality assurance/quality control activities to ensure quality data for confidence in decisions. An overview of the MR process is presented, as well as particular quality considerations at critical decision points for MR projects. Planning for each decision point requires specific quality metrics be assigned and ongoing monitoring confirms project objectives are met.

(LNAPL-3)

LNAPL-3 builds upon and supersedes both previous ITRC LNAPL guidance documents in an updated, web-based format. LNAPL-1 and LNAPL-2 are still available for review; however, LNAPL-3 is inclusive of those materials with new topics presented and previous topics elaborated upon and further clarified.

This guidance can be used for any LNAPL site regardless of size and site use and provides a systematic framework to:

• develop a comprehensive LNAPL Conceptual Site Model (LCSM) for the purpose of identifying specific LNAPL concerns;
• establish appropriate LNAPL remedial goals and specific, measurable, attainable, relevant, and timely (SMART) objectives for identified LNAPL concerns that may warrent remedial considerations;
• select remedial technologies that will best achieve the LNAPL remedial goals for a site, in the context of the identified LNAPL concerns and conditions; and
• evaluate the implemented remedial technologies to measure progress toward an identified technology specified endpoint

Also provide a technical overview of NSZD for LNAPL and the methods by which rates can be estimated and measured. For this document, the original ITRC NSZD document (LNAPL-1) was updated and incorporated into the main body and appendix.

(FracRx-1)

This guidance explains the processes controlling contaminant fate and transport in fractured rock, as well as innovative approaches to managing these sites. Additionally, this guidance describes how to develop a useful conceptual site model (CSM) and how to identify strategies to remediate and monitor contamination in fractured rock. Characterizing and remediating contaminated fractured rock sites must account for the complexities of structural control of contaminate fate and transport. Experience and a combination of skills from a number of disciplines is necessary to unravel inherent complexities of fracture flow and control. In as much as the process of characterization and remediation fractured rock is similar to an unlithified subsurface the investigation and tools differ. A Tool selection table is included to streamline the process of considering a set of tools able to collect the correct data.

(BCS-1)

The Bioavailability in Contaminated Soil document describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into human health risk assessment. This guidance addresses lead, arsenic and polycyclic aromatic hydrocarbons for the incidental ingestion of soil.

(RMCS-1)

This guidance document provides readers with practical steps to manage the remediation process at complex sites where remediation progress is uncertain and remediation is not anticipated to achieve closure or even long-term management within a reasonable time frame. Readers will learn the following: 1) Identify and integrate technical and nontechnical challenges into a holistic approach to remediation, 2) Use a Remediation Potential Assessment to identify whether adaptive site management is warranted due to site complexity, 3) Understand and apply adaptive site management principles, 4) Develop a performance-based long-term management plan, 5) Apply well-demonstrated techniques for effective stakeholder engagement, and 6) Review in-depth case studies of real-world applications of remediation and remediation management at complex sites.

(IC-1)

This guidance focuses on long-term contaminant management using institutional controls (ICs). ICs are a form of land use controls (LUCs) that provide protection from exposure to contaminants on a site. While ICs consist of administrative or legal restrictions on a site, LUCs can also use physical measures, which are called engineering controls (ECs). In contrast to ECs, ICs are primarily government controls, proprietary controls, enforcement or permit mechanisms, and informational devices. In many states ICs are approved as part of a remedy. The IC may be the sole remedy or may be used in conjunction with other remedies or ECs. The protectiveness of the IC depends on management elements that ensure its integrity throughout its life cycle. When the critical elements of an IC are jeopardized, or fail, direct impact to human health and the environment can occur.

(GRO-1)

The Geospatial Analysis for Optimization at Environmental Sites (GRO-1) web-based guidance is designed to help practitioners better apply geospatial analyses in environmental projects. This guidance will help state regulators and other practitioners to understand, evaluate, and make informed decisions about geospatial analyses for optimizing activities at environmental sites. The material presented provides not only highly technical detail, but also introductory information for those who may not have expertise in this area. The document applies to all project life cycle stages: release detection, site characterization, remediation, monitoring and closure. The GRO-1 web-based technical and regulatory guidance document brings clarity to the planning, implementation, and communication of geospatial analysis in support of optimization. The GRO-1 document is a companion document to Groundwater Statistics and Monitoring Compliance (GSMC-1).

The GRO-1 document is formatted as a website. You can access the web document at any time from the ITRC website or you can bookmark the link. The fact sheets and review checklist are downloadable in a printable format (PDF). The software tables are in a downloadable Excel file. To print material from the website, use the “Print this page” link at the bottom of each page.

(GCMR-2)

This web-based guidance document explains the process of geophysical classification, describes its benefits and limitations, and most importantly discusses the information and data needed by regulators to monitor and evaluate the use of the technology. This document also emphasizes using a systematic planning process to develop data acquisition and decision strategies at the outset of a munitions response effort, as well as quality considerations throughout the project. Stakeholder issues that are unique to munitions response are also discussed

This guidance document is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites.

(RISK-3)

Assists effective decision-making among state, local, and federal project managers and decision makers tasked with developing or reviewing risk assessments for contaminated sites using site-specific approaches, scenarios, and parameters. The document discusses commonly encountered issues organized around seven risk-assessment subjects (planning, data evaluation, toxicity, exposure assessment, risk characterization, risk management, and risk communication) when site-specific alternatives are proposed, and provides options for addressing these issues. Links to resources and tools that provide more detailed information on the specific issues and potential options are also provided. Community members and other stakeholders may find this document helpful for understanding and using risk assessment information to make better environmental decisions.
