Effectiveness of Point of Entry Systems to Remove Select Per- and Poly- fluoroalkyl Substances from Drinking Water

Per- and poly-fluoroalkyl Substances (PFAS) contamination of groundwater sources in the U.S. is a widespread problem for the drinking water industry. Well water supplies in the municipalities of Fountain, Security, and Widefield, Colorado, contain Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) greater than U.S. Environmental Protection Agency (EPA) health advisory level of 70 nanograms/liter (ng/L). The source of PFAS in the well water has been associated with aqueous film forming foam (AFFF) at Peterson Air Force Base (AFB). Several public water systems and numerous private well owners use the impacted Widefield Aquifer as their sole source of drinking water. To assist property owners and limit exposure of PFAS in residential drinking water systems, treatability studies were conducted by EPA on the PFAS removal effectiveness of commercially available Point-of-Use (POU)/Point-of-Entry (POE) units using Reverse Osmosis (RO) treatment and Granular Activated Carbon (GAC) adsorbents. Household water systems were tested with a representative test water with the water quality characteristics and six PFAS contaminants found in Widefield Aquifer region groundwater samples. The study also documented the ease of use during installation, startup, and continuous/intermittent operation of the water systems.

Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment

Risk-based cleanup goals are often calculated assuming that chemicals present in soil are absorbed by humans as efficiently as the chemicals dosed during the toxicity tests used to determine regulatory toxicity values (such as the Reference Dose or Cancer Slope Factor). This assumption can result in inaccurate exposure estimates and associated risks for some contaminated sites because the amount of a chemical absorbed (the chemical�s bioavailability) from contaminated soil can be a fraction of the total amount present. Properly accounting for soil-chemical interactions on the bioavailability of chemicals from soil can lead to more accurate estimates of exposures to soil contaminants and improve risk assessments by decreasing uncertainty.
The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. This guidance addresses lead, arsenic, and polycyclic aromatic hydrocarbons (PAHs) because evaluating bioavailability is better understood for these chemicals than for others, particularly for the incidental ingestion of soil.
The target audience for this guidance and training course are:

Project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs.
Risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site.

As a participant in this training you should learn to:

Value the ITRC document as a �go-to� resource for soil bioavailability
Apply the decision process to determine when a site-specific bioavailability assessment may be appropriate
Use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability
Consider factors that affect arsenic, lead and PAH bioavailability
Select appropriate methods to evaluate soil bioavailability
Use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessment

Learners can envision themselves implementing the ITRC guidance through case study applications. Training participants are encouraged to view the associated ITRC guidance, Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1) prior to attending the class.

Characterization and Remediation of Fractured Rock

Characterization and remediation of contaminated groundwater in fractured rock has not been conducted or studied as broadly as groundwater at unconsolidated porous media sites. This unfamiliarity and lack of experience can make fractured rock sites perplexing. This situation is especially true in portions of the U.S. where bedrock aquifers are a primary source of drinking and process water, and demands on water are increasing. As a result, remedial activities often default to containment of contaminant plumes, point of use treatment and long-term monitoring rather than active reduction of risk. However, this attitude does not incorporate recent advances in the science and technology of fractured rock site characterization and remediation.
The basis for this training course is the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. These differences are the focus of this guidance.

By participating in this training class, you should learn to:

Use ITRC�s Fractured Rock Document to guide your decision making so you can:

Develop quality Conceptual Site Models (CSMs) for fractured rock sites
Set realistic remedial objectives
Select the best remedial options
Monitor remedial progress and assess results

Value an interdisciplinary site team approach to bring collective expertise to improve decision making and to have confidence when going beyond containment and monitoring - - to actually remediating fractured rock sites.

Case studies of successful fractured rock remediation are presented to provide examples of how fractured rock sites can be evaluated and available tools applied to characterization and remediation.
Training participants are encouraged to view the associated ITRC guidance, Characterization and Remediation of Fractured Rock prior to attending the class.

Long-term Contaminant Management Using Institutional Controls

Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC�s Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of Ics. ITRC has developed a downloadable tool that steps users through the process of planning and designing IC management needs. This tool can help to create a long lasting record of the site that includes the regulatory authority, details of the IC, the responsibilities of all parties, a schedule for monitoring the performance of the IC, and more. The tool generates an editable Long Term Stewardship (LTS) plan in Microsoft Word.

After attending the training, participants will be able to:

Describe best practices and evolving trends for IC management at individual sites and across state agency programs
Use this guidance to
- Improve IC reliability and prevent IC failures
- Improve existing, or develop new, IC Management programs
- Identify the pros and cons about differing IC management approaches
Use the tools to establish an LTS plan for specific sites
Use the elements in the tools to understand the information that should populate an IC registry or data management system.

The target audience for this guidance includes environmental regulators at all levels of government, private and public responsible or obligated parties (Ops), current site owners and operators, environmental consultants, and prospective purchasers of property and their agents. Other stakeholders who have an interest in a property can also use this guidance to help understand how to manage Ics.
