A wide-ranging group of chemicals generally referred to as “emerging contaminants” (ECs) increasingly have been found in waterways and water systems. They include pharmaceuticals, chemicals in personal and consumer products, and industrial and agricultural chemicals. In many cases, the risk to human health and the environment from these chemicals is not clear, and standards and guidance applied by regulators may vary based on different interpretations of toxicity information. Tracking and navigating regulations and requirements for ECs can be challenging. Integral scientists have extensive experience monitoring international, federal, state, and local regulatory activities related to ECs. We help our clients develop effective risk management strategies to mitigate the impacts from ECs on their businesses, while remaining compliant with dynamic requirements and being good environmental and public health stewards.
Monthly PFAS Alert Newsletter
This groundbreaking newsletter covers the latest information on per- and polyfluoroalkyl substances (PFAS), including peer-reviewed publications, academic reports, media coverage, regulatory announcements, legislative decisions, and government reference documents worldwide. Each edition contains hyperlinks to online source documents, and a synopsis of the publication and its relevance to stakeholders. As an added bonus, your subscription will also include breaking news updates for high priority alerts, library retrieval services for publications of interest, and access to Integral’s senior staff to discuss the potential relevance of information referenced in the alert to you or your organization.
For more information on the subscription, contact Janet Anderson at firstname.lastname@example.org.
Emerging Contaminants: PFAS
Get the latest scientific trends, insights, and analysis in a changing regulatory climate, with access to Integral scientists to help you understand what this means to you.
Integral’s 2016 Report on State-Specific EC Activity
In 2016, Integral independently developed a state-by-state compendium based on a comprehensive analysis of regulatory activity on ECs in each state. Compiled through standardized research methods and one-on-one interviews with state regulatory representatives, this report provides a thorough and systematic evaluation of state initiatives related to emerging contaminants. EC activity is dynamic throughout the U.S., particularly for chemicals such as perfluoroalkyl substances and 1,4-dioxane. For information on the current level of EC activity by state and chemical, contact Janet Anderson, Ph.D.
Chemical-specific EC Expertise
Examples of ECs for which we have recent and extensive experience include per- and polyfluoroalkyl substances (PFAS), 1,2,3-trichloropropane (TCP), metals such as lead and arsenic, pesticides, and 1,4-dioxane.
PFAS Assessment and Management
Integral staff are on the forefront of technical and regulatory developments for PFAS. Our services include multimedia environmental sampling, field sampling programs, toxicity evaluations, treatment system design and engineering, and stakeholder communication.
Integral works with clients to design and implement strategies that reflect the latest technical knowledge and regulatory contexts. Our staff contribute to state-of-the-science approaches and research, participate on advisory boards, and lead workshops on topics involving ECs. We advise clients on ways to assess and minimize potential liabilities and offer insight on methods to conduct and streamline evaluations.
Toxicity Evaluations and Risk Assessment
We have unique experience assessing human exposure to ECs, including design and data analysis of human serum biomonitoring studies and assessing site-specific exposure compared to national baseline levels. One of our key staff formerly led the U.S. Air Force Emerging Issues/Contaminants Program, and others are nationally known for their work on changes in toxicity standards and regulations.
Integral has performed treatment technology evaluations for 1,4-dioxane, PFAS, 1,2,3-TCP, and other ECs. We are experienced in the evaluation of technology effectiveness, implementability, and cost. Our engineers have completed numerous remediation system designs, including those for potable water treatment systems.
Fate and Transport
Integral has evaluated fate and transport of PFAS, sulfolane, 1,4-dioxane, 1,2,3-TCP, and other ECs to support litigation, assessment of human health risk issues, remedial investigations, and design of site-specific risk management and remediation strategies. Central to Integral’s approach is development of an accurate conceptual site model (CSM) using multiple lines of evidence. The CSM describes the interplay of physical, chemical, and biological processes governing contaminant fate and transport, as well as relevant toxicity and risk assumptions. Our approach allows us to negotiate remedies and risk mitigation plans based on defensible science.
