Technical Guidance Documents
At the implementation level, the wide variety of pollutants, technologies and approaches means that some projects may require detailed support on specific details. The Technical Guidance section provides links to key sources of information, tailored guidance, and responses to common concerns.
TAG provides guidance documents on specific topics related to polluted sites. Members can request TAG prepare technical guidance specific to their needs.
Risk Assessment
USEPA Superfund Approaches
Risk assessment is a fundamental part of selecting priority projects and then implementing them. A risk assessment can be applied to address health and or ecology impacts and can be carried out in increasing levels of detail, depending on objectives and resources.
Risk assessment is a formal and critical step in the implementation of Superfund in the USA, implemented by EPA. Guidance for risk assessors working in this context is provided by EPA. The level of detail provided may be beyond the immediate needs of implementing bodies in other countries but it provides an understanding of the scope and practical application of risk assessment.
GAHP Guidance Note
Implementation of remediation projects
Author: Technical Advisory Group
This guidance addresses processes for implementation of remediation projects, from the point of view of the implementing agent or authority. Projects will have to be consistent with the specific procedures of national authorities and/or with donor requirements but broadly similar approaches would generally apply to all projects. The note provides a possible agenda for discussions on the preparation and implementation of the project.

Establishing a Remediation Program
Author: Technical Advisory Group
Description: This Guidance Note addresses the main elements of a program for identification and prioritization of remediation interventions. The specific components must reflect the national systems, legislatoin and institutions but there are a number of steps which will be common to most situations.

GAHP Guidance Note
Soil Screening Levels
Author: Technical Advisory Group
This guidance addresses the selection and use of “screening levels” in prioritizing contaminated sites for remediation efforts. It responds to requests from agencies for advice for situations where there are no national screening levels to apply.
GAHP Guidance Notes provide information on international good practices and regulations in remediation. They are prepared to assist GAHP members in dealing with practical problems of remediation of polluted sites and are intended to assist readers to identify key points that should be taken into account in reviewing or approving any proposal.
GAHP Guidance Note
Containment of Lead Material
Author: GAHP Technical Advisory Group (TAG)
This guidance addresses the appropriate use and the key design elements of onsite engineered containment systems, where this is an option for lead-bearing material collected during the process of remediating lead-contaminated sites.

CLU-IN Resources: Contaminated Site Clean-Up Information
Contaminated Site Clean-Up Information (CLU-IN) provides information about innovative treatment, characterization, and monitoring technologies to the hazardous waste remediation community. Developed by the U.S. Environmental Protection Agency (EPA), CLU-IN is intended as a forum for all waste remediation stakeholders.
