ITRC Groundwater Statistics for Environmental Project Managers - April 6, 2017, 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. For more information and to register, see
or Superfund Redevelopment Initiative Series: Restoring Superfund Sites to Public Good - April 13, 2017, 2:00PM-3:30PM EDT (18:00-19:30 GMT). Superfund
sites can be reused in many ways, but many local governments are seeing unique opportunities to use sites for public or local government purposes. From roads
to firefighting training facilities, local governments who own or acquire Superfund sites are finding ways to put these properties to good use. For more information
and to register, see Analytical Tools and Methods: Session I - Field-ready Biosensors to Assess Bioavailability and Toxicity - April 17, 2017, 1:00PM-3:00PM EDT (17:00-19:00
GMT). This webinar series highlights innovative analytical tools and methods developed and used by Superfund Research Program (SRP) grantees. The presenters
will feature the benefits of these new tools and methods compared to conventional methods. They also will include information about how the technology has
helped to facilitate ongoing SRP research. In the first session, researchers will describe their tools to assess bioavailability/toxicity for more effective
human and/or environmental monitoring. Treatment assessments and water quality monitoring that rely only on measuring the reduction of target contaminant
concentrations are often insufficient because they do not consider the complex and broader risks that specific contaminants or mixtures and their transformation
products pose to the environment and human health. For more information and to register, see ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - April 18, 2017, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Chemical
contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when
these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate
indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor
intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids
(LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. The ITRC
Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014)
and this associated Internet-based training provides regulators and practitioners with consensus information based on empirical data and recent research
to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident
decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology
for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision
making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway
can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators
and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites. With the ITRC GRO-1
web-based guidance document and this associated training class, project managers will be able to: evaluate available data and site needs to determine if geospatial
analyses are appropriate for a given site; for a project and specific lifecycle stage, identify optimization questions where geospatial methods can contribution
to better decision making; for a project and optimization question(s), select appropriate geospatial method(s) and software using the geospatial analysis
work flow, tables and flow charts in the guidance document; with geospatial analyses results (note: some geospatial analyses may be performed by the project
manager, but many geospatial analyses will be performed by technical experts), explain what the results mean and appropriately apply in decision making;
and use the project manager's tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently
in decision making. For more information and to register, see or Leveraging Resources for Brownfields Revitalization: Meet the Funders - Finance - April 25, 2017, 1:00PM-2:30PM EST (17:00-18:30 GMT). This 'Meet the

land cover. Some of the land that is 'taken' for urban development is covered with an impervious surface, which severely hampers ecosystem functioning and
the related delivery of ecosystem services. This document offers an initial exploration of how to apply LCT and the LCA methodology to the environmental assessment
of developing brownfields and greenfields. View or download at ... > Conferences and Symposia Groundwater High-Resolution Site Characterization (HRSC), San Francisco, CA, June 13-14, 2017. This training course focuses on groundwater characterization
and discusses (1) the impacts of subsurface heterogeneity on the investigation and cleanup of groundwater and related media, (2) the need for scale-appropriate
measurements and adequate data density, and (3) the tools and strategies that are available to overcome the impacts of subsurface heterogeneity. After taking
this course, participants will be armed with information that will allow them to improve their subsurface investigation approaches and develop more realistic
and comprehensive conceptual site models (CSM). CSMs developed based on HRSC strategies and tools will decrease site uncertainty, improve the remedy selection
process for groundwater remedies, and better enable the evaluation, design, and implementation of targeted in situ and ex situ groundwater remedies. The
Groundwater HRSC course is an advanced 2-day course. The recommended audience includes EPA, federal, state, tribal and private industry technical project
managers, practitioners and other stakeholders involved in groundwater investigation and remediation. For more information and to register, see
