In this Waste Today article, Sam Cooke discusses the factors, treatment options, analytical methods, and identifying PFAS sources to most effectively reduce the concentrations of ammonia and PFAS in landfill leachate.
Reducing these concentrations help meet discharge permit requirements for direct discharge of treated leachate to surface waters and to meet publicly owned treatment works (POTW) discharge permit standards.
Sam points out that accomplishing ammonia and PFAS reduction with established wastewater treatment technologies works, but the right treatment depends on each site’s specific parameters. He suggests conducting bench-scale and pilot-scale testing for any feasible nitrogen removal or treatment system. Testing the wastewater helps to identify any changes in the concentration of nitrogen compounds. Thus, necessary changes to the treatment processes, such as additional aeration or chemical additions are easier to identify and less costly to implement.

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.

As concern from the presence of polyfluoroalkyl substances, or PFAS, rises, actions are being taken to address the chemicals on military installations. While specific actions vary according to circumstances at each location, the military is acting to address affected drinking water through a number of programs. This article published in The Military Engineer, No. 725 …
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 …
The California State Water Resources Control Board (SWRCB) issued an order requiring mandatory environmental assessments at 271 chrome plating facilities. SCS explains why the facilities should comply, what to plan for, what to sample, and more to avoid civil liability (up to $5,000 per day) for non-compliance. The SWRCB deadline for facilities to respond and take action is very short – January 31, 2020.

Part one of a two-part series looks at the health and environmental implications of PFAS, as well as the lack of research and federal regulation around these chemicals.
Part two of a two-part series breaks down the efforts some states are making, as well as steps being taken to manage this chemical waste flow.
PFAS chemical removal is essential to keep drinking water clean in communities where PFAS chemicals have contaminated the water supplies. None of the current technologies are capable of both removing and destroying PFAS simultaneously. A combination of technologies may be the best approach in order to overcome the limitations of ionic exchange. A combination of adsorption followed by …
Polyfluorinated and perfluorinated alkyl substances (PFAS) are detected in waters around the world, posing a threat to drinking water quality.
EPA Announces New Method to Test for Additional PFAS in Drinking Water
December 19, 2019
Today, the U.S. Environmental Protection Agency (EPA) took another key step in implementing the agency’s PFAS Action Plan by announcing a new validated method for testing per- and polyfluoroalkyl substances (PFAS) in drinking water. This new validated test method complements other actions…
Yesterday, the U.S. Environmental Protection Agency (EPA) sent the proposed regulatory determination for perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in drinking water to the Office of Management and Budget for interagency review. This step is important …
Per- and poly-fluoroalkyl substances (PFAS) are receiving increasing attention from regulators and the media. Within this large group of compounds, much of the focus has been on two long-chain compounds that are non-biodegradable in the environment: PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid). Long detected in most people’s bodies, research now shows how “forever chemicals” …
PFAS Treatment – The Devil We Know and Need to Manage November 2019
PFAS are a class of synthetic fluorinated chemicals used in many industrial and consumer products, including defense‐related applications. They are persistent, found at low levels in the environment, and bio‐accumulate. Studies have shown these compounds being detected more often in surface water, sediments and/or bioaccumulated into fish tissue. Because of the greater affinity of …
This week, 271 chrome plating facilities in California received an order from the California State Water Resources Control Board (SWRCB) mandating the investigation of Per- and poly-fluoroalkyl substances (PFAS) at their facilities. Up until 2016, fume suppressants used by these facilities often contained perfluorooctanesulfonate (PFOS), a variety of PFAS. PFAS consists of thousands of entirely …
Are You Ready to Address PFAS? October 2019
State actions have resulted in a variety of state groundwater standards for specific PFAS compounds, including some that are significantly lower than the USEPA advisory levels. These changes mean new potential liabilities and consequences for organizations that manufacture, use, or sell PFAS or PFAS-containing products, and for the current owners of properties affected by historic PFAS use. Questions for manufacturers, property owners, and property purchasers include…
The 5Ws of Environmental Insurance An environmental insurance claim is simply the response and mitigation of an environmental issue or event paid for by an environmental insurance policy. Similar to an auto or home insurance claim, a company or individual purchases this type of policy to protect them in case a matter arises about …
Following the release of the U.S. Environmental Protection Agency’s PFAS Action Plan, many states have begun to draft plans and take action to address per- and polyfluoroalkyl substances (PFAS). PFAS have been used in the production of a wide range of industrial and household products, including fire suppressant foam (Aqueous Film-Forming Foams or AFFF) stored …
Managing landfill leachate and wastewater treatment are increasingly challenging and costly for landfill owners and operators. In some cases, publicly owned treatment works (POTWs) are required to impose limitations on liquids received at their facilities, resulting in increased charges, or the POTW could refuse to permit or process the leachate wastewater altogether. These developments are …
Join Forester University for this educational webinar as speaker Dan Sola of SCS Engineers, encourages you to take a deep breath regarding PFAS as he walks us through what we know, what we don’t know, and where we are likely heading. Sola’s goal is to provide a deeper understanding of what these chemicals are, how they exist in the environment, what we know about cleaning them up, and how to think about a fiscally responsible management strategy in an environment of fast-changing regulations.
Forester University 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 …
