PFAS false-positive detections can lead to unnecessary expense and investigations

January 22, 2020

When a release of PFAS occurs at a metal finishing facility, it is often due to the integrity of the wastewater system. Due to the persistence of PFAS and very low concentrations considered to be toxic, even water containing a small amount of PFAS can result in a large impact on the environment. If water can migrate into the subsurface, so can PFAS. Once in the soil, any water introduced into the soil can transport the PFAS into the groundwater.

The Californian chrome plating facilities are being required to test for PFAS even if there is no evidence of historical contamination at the property from any chemicals. Current testing is requiring the analysis of 25 different kinds of PFAS, including PFOS and 6:2 FTS.

Because such low concentrations of PFAS are considered to be toxic and their prevalence in common consumer products and tools, false-positive detections are common during the investigations for PFAS. False positives detections can lead to unnecessary expense and additional investigations. Therefore, selecting a knowledgeable, skilled, and experienced environmental consulting firm, is paramount to keeping the investigation as low cost as possible.

SCS Engineers PFAS Library – Open to the Public

January 15, 2020

PFAS are a class of synthetic fluorinated chemicals used in many industrial and consumer products, including defense‐related applications and firefighting. They are persistent, found at low levels in the environment, and bio‐accumulate. Studies have shown these compounds being detected more often.

The USEPA is positioned to take serious action on PFAS in 2020, regulators in many states have already started to implement their own measures, while state and federal courts are beginning to address legal issues surrounding this emerging contaminant.

SCS Engineers has created a library of PFAS articles and resources for industry associations, local, state, and federal agencies,  and the public. This SCS blog is a list of information and educational material related to emerging contaminants. As we add new materials we will send updates via the SCS Engineers blog and social media sites.

At SCS, your privacy is assured. We encourage you to share these resources using your email or social media account; you can do this from each website page using the light blue icons shown on the left side of each resource.

1, 2, 3 – TCP: California’s Response to a Persistent Pollutant Could Help Other States

January 14, 2020

The U.S. Environmental Protection Agency (EPA) has identified 1, 2, 3 – Trichloropropane (TCP), which does not occur naturally in the environment, as an emerging chemical of concern that can threaten drinking water supplies. It states that TCP is a persistent pollutant in groundwater and has classified it as “likely to be carcinogenic to humans.” California State Water Board member Steven Moore called TCP an “insidious chemical” because it persists in the environment, sinks in water and is harmful in even tiny doses. Currently, there is no federal maximum contamination level (MCL) for TCP; however, there is a federal non-enforceable health-based screening level of 0.00075 ug/L.

Since 2012, TCP has been on the emerging Contaminant Candidate List (CCL), which is a watch list of unregulated contaminants that are known to, or anticipated to, occur in public water systems and may require regulation under the Safe Drinking Water Act (SDWA). The EPA has required, under the Unregulated Contaminant Monitoring Rule (UCMR), that large water systems test for TCP every five years with a minimum reporting level of 0.03 μg/L. This rule allows for the EPA to monitor contaminants suspected to be in drinking water that are unregulated under the SDWA. As a result of the testing, TCP has been identified across the US in drinking water sources. Currently, there is no federal maximum contamination level (MCL) for TCP; there is a federal non-enforceable health-based screening level of 0.00075 ug/L.

The author continues the paper with an examination of what TCP is and how it impacts our environment and our health. She then discusses regulatory policies and how California’s mandatory TCP standard could be a blueprint for other state water agencies currently investigating how to enhance their own drinking water protections from emerging contaminants.

Lyn covers some of the legal aspects, risks to businesses, detection, and treatment options to conclude her white paper. She also provides plenty of resources to start the journey toward sustainable treatment solutions that communities can afford.

The Evolving Concern of PFAS at Airports – Mitigating the Risks

January 9, 2020

PFAS are also key components in aqueous film-forming foam (AFFF), which is used to fight petroleum-based fires at aviation and manufacturing facilities. For decades, AFFF containing PFAS has been used extensively at airports throughout the world to protect the safety of passengers, crew, and others. The FAA requires that commercial airports train with, calibrate equipment with, and use the best performing AFFF fire suppression systems. AFFF is required to be used at airports and must be certified to meet strict performance specifications, including those mandated by the  U.S. Department of Defense Military Specifications.

How can airports, the aviation industry, and manufacturers begin to mitigate PFAS health risks?

 

Lynleigh Love and Chris Crosby of SCS Engineers discuss the risks and issues with PFAS-based firefighting foam used at airports. The authors cover the regulatory climate,  contamination investigations,  operational and environmental management and litigation, along with alternatives to using traditional AFFF. There are some possible alternatives that can mitigate health risks in your community.

Read this article to help inform your mitigation plan and strategies to minimize risk.

All About PFAS: Emerging Contaminants That Are Everywhere

July 29, 2019

Forester University recently hosted Dr. Viraj deSilva P.E., BCEE of SCS Engineers in their well-received educational webinar “All About PFAS: Emerging Contaminants That Are Everywhere.”

Dr. deSilva teaches you all you need to know to protect yourself and your community from PFAS—from generation, formation, and environmental release to sampling and analysis.

He provides an in-depth overview of the treatment of PFAS in sources that do not currently have maximum containment levels, such as landfill leachate, wastewater, surface water, and groundwater.

This course covers nomenclature, chemistry, sources, exposure, and future concerns as well as discusses the current regulatory status of these contaminants.

Learning Objectives

  • Identify sources of PFAS contamination and associated health concerns
  • Learning the chemical properties of PFAS compounds and why they are hard to degrade
  • Taking an inventory of detected PFAS compounds in landfill leachate, wastewater, and drinking water
  • Discovering methods used to analyze PFAS samples
  • Discussing the current regulatory status of PFAS chemicals
  • Exploring the treatment methods of PFAS compounds and managing waste streams from these treatment processes
  • Comparing PFAS concentrated residual management options and associated issues
