ITRC Remedy Selection for Contaminated Sediments - June 2, 2016, 1:00PM-3:15PM EDT (17:00-19:15 GMT). ITRC developed the technical and regulatory guidance, Remedy Selection for Contaminated Sediments (CS-2, 2014), to assist decision-makers in identifying which contaminated sediment management technology is most favorable based on an evaluation of site specific physical, sediment, contaminant, and land and waterway use characteristics. The document provides a remedial selection framework to help identify favorable technologies, and identifies additional factors (feasibility, cost, stakeholder concerns, and others) that need to be considered as part of the remedy selection process. This ITRC training course supports participants with applying the technical and regulatory guidance as a tool to overcome the remedial challenges posed by contaminated sediment sites. Participants learn how to: identify site-specific characteristics and data needed for site decision making, evaluate potential technologies based on site information, and select the most favorable contaminant management technology for their site.

ITRC Groundwater Statistics for Environmental Project Managers - June 7, 2016, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background, compliance, trend analysis, and monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management.

Revised ASTM Standard Guide for Greener Cleanups (E2893-16). The ASTM Standard Guide for Greener Cleanups is intended to encourage property owners, regulatory agencies, responsible parties, developers and communities to voluntarily use greener practices for contaminated site cleanup. EPA representatives recently worked with ASTM International to update the standard guide, which was originally issued in 2013. The revised standard released by ASTM International in May 2016 contains refinements to the "Greener Cleanup BMP Table" appearing as Appendix X3 and continues to describe a process for identifying, evaluating and incorporating best management practices (BMPs) and options for quantifying the environmental footprint of a cleanup. For more information about and to purchase the revised standard, visit For background and additional information about greener cleanups, visit

ProUCL 5.1 is Now Available. The EPA Site Characterization and Monitoring Technical Support Center (SCMTSC) has updated ProUCL to version 5.1.00 (5.1). ProUCL version 5.1 is a comprehensive free statistical software package with statistical methods and graphical tools to address many environmental sampling and statistical issues. Version 5.1 is a general update to version 5.0 correcting known bugs, crashes, and unhandled exceptions (e.g., on bad data sets). In ProUCL 5.1, enhancements have been made in the Trend Analysis option of the Statistical Test module. ProUCL 5.1 computes and outputs residuals for the non-parametric T-S trend line which may be helpful to compute a prediction band around the T-S trend line. In addition to generating Q-Q plots based upon detected observations, the Goodness of Fit Tests (GoF) option of the Statistical Tests module of 5.1 generates censored probability plots for data sets with NDs. Some changes have also been made in the decision table used to make suggestions for UCL selection based upon a gamma distribution. Download at

Superfund Research Program Research Brief 257: Using Field Data and Numerical Modeling to Assess Vapor Intrusion Risk. A recent Superfund Research Program (SRP) study reveals that measurements of chemical concentrations in groundwater may not be a good indicator of whether the chemicals are seeping into buildings and contaminating indoor air. The findings provide insight into how an approach incorporating multiple lines of evidence, including soil gas measurements and a 3-D model, can be used to better evaluate exposure risks from vapor intrusion into homes and buildings.

Land Contamination and Brownfield Management Policy Development in China: Learning from the UK Experience (2016). China's government has begun to lay the foundation for market growth which will bring a wide variety of opportunities for business with soil protection and remediation still in the early stages of development. In common with other emerging land contamination markets, China stands to benefit from comprehensive and systematic planning for risk based land management, encompassing both contaminated soil and groundwater. Future collaboration on land contamination management and policy between China and the UK should be sustained, as the UK has developed mature market and management systems for land contamination.

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - ITRC 2-day Classroom Training, Somerset, NJ, September 26-27, 2016 AND Framingham, MA, November 9-10, 2016. Preapproved for continuing education for CT LEPs, MA LSPs, NJ LSRPs, and SC PGs. This 2-day ITRC classroom training is based on the ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and led by internationally recognized experts. Within the training class - hear about EPA's Technical Guide For Addressing Petroleum Vapor Intrusion At Leaking Underground Storage Tank Sites (June 2015). The ITRC guidance document and EPA guide are complementary documents with the ITRC training course providing the "how-to" knowledge and skills for screening, investigating, and managing the petroleum vapor intrusion pathway. The class will enable you to develop the skills to screen-out petroleum sites based on the scientifically-supported ITRC strategy and checklist; focus the limited resources investigating those PVI sites that truly represent an unacceptable risk; and communicate ITRC PVI strategy and justify science-based decisions to management, clients, and the public. Interactive learning with classroom exercises and Q&A sessions will reinforce these course learning objectives. For local, state, and federal government; students; community stakeholders; and tribal representatives, ITRC has a limited number of scholarships (waiver of registration fee only) available.

Incremental-Composite Soil Sampling, Chicago, IL, July 28, 2016. This full-day course focuses on the theory and application of ITRC's Incremental Sampling Methodology (ISM), composite sampling designs, and hybrids of the two (Incremental-Composite Sampling, ICS). ICS hybrid designs are useful to address multiple project goals simultaneously. Since "representativeness" is a key aspect of data quality and ISM/ICS data are demonstrably more representative than most discrete data, it will be argued that ICS data are indeed "better" than non-ICS data. The course will answer questions such as: What is the difference between ITRC's ISM and EPA's Incremental-Composite Sampling (ICS) strategies? Is there written EPA guidance? What features should an ISM or ICS design have? Can ICS give project risk assessors the data they want, while simultaneously meeting the RPM's own data needs for characterization or remedial design? How are background concentrations determined and comparisons to background handled using ICS? How do we know whether ICS "worked" for the project? For more information and to register, see
