PFAS – the financial and logistical challenges for landfills

December 2, 2020

Across the industry, stakeholders agree the next few years will be critical in shaping how landfills deal with PFAS and how the public perceives it. Waste trade associations, scientists, and a host of organizations are in the midst of conducting a number of studies looking closely at the issue, PFAS treatment options, the positive impact of recycling, and regulatory policies.

While there are sites noted in the article, there’s no practical way for most companies and landfills to respond at this time responsibly. Additionally, landfills are unique; no two are alike. Most human exposure to PFAS occurs through contaminated food. The majority of landfill leachate is pre-treated at the landfill before going to a wastewater treatment plant, where additional treatment occurs before discharge.

According to EREF President Dr. Bryan Staley, in the article, “The relative impact of leachate as a human exposure pathway needs further evaluation to understand its relative degree of importance as it relates to health implications.”

Dr. Gomathy Radhakrishna Iyer, landfill leachate and design expert for SCS Engineers, said some operators are waiting to see what regulations may come even as they work on accounting for potential compliance issues and seeking solutions. “When the clients are thinking of upgrading their treatment plans, some are definitely taking into consideration PFAS treatment,” Radhakrishna Iyer said.

“You’re spending millions of dollars, you need to do your due diligence, right? At this point, consideration should be given to PFAS treatment during the feasibility stages,” she said.

Unperplexing PFAS and Liquids Management

November 2, 2020

Complementing the Interstate Technology and Regulatory Council’sITRC, PFAS Technical and Regulatory Guidance, the website now has ITRC Per- and Polyfluoroalkyl Substances – PFAS, and Risk Communication Fact Sheets available. The site and updated content replace older fact sheets with more detailed information and useful for those who wish to understand the discovery and manufacturing of PFAS, information about emerging health and environmental concerns, and PFAS releases to the environment with naming conventions and federal and state regulatory programs.

SCS Engineers’ professionals recommend further reading to understand specific chemicals or subgroups of chemicals under study to comprehend PFAA behavior in the environment. There are appropriate tools to develop a site-specific sampling and analysis program and considerations for site characterizations following a PFAS release.

We combine ITRC resources and our own to compile an updated library that we hope you find helpful. You can always contact one of our local Liquids Management or Landfill professionals too.

PFAS Behavior in the Environment

PFAS Concerns

PFAS Evaluations

Real Estate Development – New PFAS Policies Impact Environmental Due Diligence

August 27, 2020

scs engineers remediation - soil, air, water - emerging contaminants such as PFAS

Perfluoroalkyl and polyfluroalkyl substances (PFAS) and other emerging contaminants are becoming increasingly important for real estate transactions.  Several states have adopted or proposed health guidelines or Maximum Contaminant Levels (MCLs) for PFAS in their state. States with adopted limits include CA, CT, CO, MN, NC, NH, NJ, and VT; and states with proposed limits include IL, MA, MI, and NY.  You can track bills by state here.

The Wisconsin Department of Natural Resources (WDNR) and the Environmental Protection Agency (EPA) are focusing their attention on these contaminants. The WDNR recently issued letters to more than 3,000 responsible parties listed with open cases on the DNR’s Bureau for Remediation and Redevelopment Tracking System (BRRTS) requesting they review PFAS use at open sites. Read a sample of the DNR letter.

With WDNR’s increasing focus on PFAS, a lack of sufficient due diligence, which includes evaluations for PFAS, could lead to significant additional liability for property purchasers, developers, and lenders. In addition, a lack of sufficient assessment could lead to a delay in case closure even after responsible parties have addressed all other contaminants and potential exposure pathways at a site. A sufficient assessment for PFAS will depend on site-specific factors and should carefully consider the associated risks and liabilities.

For real estate buyers, owners, developers, lenders, brokers, and contractors the potential presence of PFAS at a property presents significant liabilities that need to be incorporated into due diligence procedures and safe work plans. The investigation and remediation of sites with PFAS contamination can be expensive, and the WDNR is working to define enforceable cleanup goals for soil and groundwater.

About PFAS

PFAS are often referred to as “forever chemicals” due to their inability to be broken down in the environment. Due to the very high toxicity of PFAS, the proposed groundwater standard is extremely low – in the parts per trillion, which is more than 100 times lower than the groundwater standards for other well-known toxic contaminants such as benzene from gasoline or tetrachloroethylene commonly used at dry cleaners and industrial facilities.

PFAS are found in a wide variety of products, including nonstick coatings (e.g., Teflon), water-repellent coatings used on clothing and food packaging, fume suppressants, and firefighting foams. Potential sources of PFAS include many types of manufacturing and processing facilities, locations where firefighting foams have been used, metal plating facilities, wastewater treatment plants, and many more.

PFAS systems can treat and clean sources and remediation solutions by environmental engineers can bring properties back to life; safe to build and live on.

How do you like your cheeseburger? Lettuce, tomato, hold the PFAS

August 17, 2020

Chemical companies are phasing out certain PFAS commonly used in fast food wrappers – read the full story and report at C&EN.

Chemical manufacturers are planning to gradually ramp down sales of certain short-chain per- and polyfluoroalkyl substances (PFAS) used as grease-proofing agents on fast food wrappers, take-out containers, and other paper-based food packaging, the US Food and Drug Administration announced July 31.

AGC Chemicals Americas, Archroma Management, and Daikin America will phase out sales of substances that contain 6:2 fluorotelomer alcohol (6:2 FTOH) for use in paper and cardboard food packaging beginning in January 2021. The process is expected to take 3 years, with up to an additional 18 months to use up existing stocks. A fourth company, Chemours, told the FDA last year that it has already stopped selling the substances in the US market.

PFAS that contain 6:2 FTOH replaced long-chain PFAS in food packaging nearly a decade ago because of concerns about the safety of long-chain PFAS, which are linked to cancer and immune disorders. FDA scientists, however, are now questioning the safety of those replacements. Data from rodent studies suggest that 6:2 FTOH accumulates in the body, the FDA reported in January (Toxicol. Appl. Pharmacol. 2020, DOI: 10.1016/j.taap.2020.114878).

“The data suggest the potential of 6:2 FTOH to also persist in humans from chronic dietary exposure,” the FDA says in a statement. “Further scientific studies are needed to better understand the potential human health risks from dietary exposure to food-contact substances that contain 6:2 FTOH.”

Rather than conduct those tests, the three manufacturers of the substances in question agreed to phase out sales in the US. – read the full story and report at C&EN.
