We hope you can join SCS Engineers and Dr. Craig Benson, who studies the phenomenon, to our free, non-commercial webinar entitled “Identifying and Managing Elevated Temperature Landfills.”
At this session, you’ll get an update on the knowns and unknowns of ETLF conditions.
Our ETLF session is for landfill owners, operators, technicians, field personnel, engineers, and regulators interested in learning about the latest research and mitigation strategies from the foremost experts in the field.
We encourage audience engagement with our panelists. We provide the ability to ask questions anonymously. We respect and understand your time constraints; those unable to stay on the live session will automatically receive a link to a recording.
ETLF Field Tips:
SCS OM&M teams look for these signs in the field data collected:
By preparing site life calculations with knowledge of multiple approaches, we can proactively position solid waste systems to meet future needs. However, the simplest approach is often the most prudent when every variable is unknown.
The growing Florida population has greatly pressured all public infrastructure, including waste disposal services. Planning for these adjusted growth trends is paramount to a successful system that provides the community with essential services. By preparing site life calculations with knowledge of multiple approaches, we can proactively position solid waste systems to meet future needs. Don’t overlook having a thorough understanding of current disposal trends and airspace utilization as the starting point for planning the future success of a solid waste system.
In their Florida SWANA presentation, Kollan Spradlin and Fauve Herron focus on using three different landfill site life calculation methods that they have previously used to assess the remaining life of Florida landfills.
Two of the three calculation methods will use service area population projections to model future waste disposal. They will also discuss a third model that does not utilize population projections — The Remaining Capacity Method. Originally developed by SCS Engineers’ founder Bob Stearns, The Remaining Capacity Method relies on past tonnage and volume utilization data to forecast the future date at which available remaining volume will be depleted.
Their Site Life Calculations presentation will cover data requirements, the drawbacks and advantages of each method, the identification of errors, and model implications.

To a wastewater treatment engineer, at least during workdays, it seems like everyone is talking about forever chemicals, all of the time. There’s a good reason for that, because the huge group of man-made chemicals has climbed in priority to be at the top of most wastewater treatment regulatory considerations. Forever chemicals are also known as per and polyfluoroalkyl substances (PFAS) and have rapidly become the latest of the emerging contaminants in drinking water to be treated. So, while there is still a lot of toxicology research to do, PFAS destruction and even which PFAS actually needs to be addressed, there is very little doubt regarding the future need to treat PFAS in landfill leachate and other wastewaters. Everyone is in agreement, the environment needs to be protected from forever chemicals.
PFAS chemicals can withstand high heat without becoming unstable as well as repelling oil and water, making them ideal for inclusion in fire-fighting foam, lining non-stick pans, or water resistant clothing. But unfortunately, PFAS can persist in the environment – water, fish, humans, etc. – for a long time. So, having efficient and cost-effective methods of treating wastewater, drinking water, bio-solids, etc., to reduce/remove PFAS is becoming increasingly important. Luckily, some traditional and very available treatment methods are effective at treating PFAS as well as some newer, non-traditional treatment methods that appear to be promising.
One effective management technology is using deep injection wells to store the PFAS contaminated wastewater deep, far below drinking water sources and within high total dissolved solids groundwater. Deep injection wells are only allowed where the deep geology and subsurface conditions can allow for the PFAS wastewater to be contained where it is injected.
Additional management options are granular activated carbon (GAC) or ion exchange (IX), which are adsorption treatment methods that use a media, through which the PFAS contaminated wastewater can pass, and the charged PFAS molecules become bound up in the opposite charged GAC or IX media.
Reverse osmosis (RO) and foam fractionation (FF) treatment methods use separation, either through very small pores in a membrane (RO) or applying aeration to create a PFAS concentrated foam (FF), to allow the treated, cleaner water to discharge the treatment process and the concentrate (RO) or foamate (FF) is left and can be dealt with more efficiently, because after treatment the concentrate/foamate is a much smaller volume than the original wastewater flow.
These PFAS management methods simply move the PFAS chemicals out of the way and don’t actually destroy the PFAS. PFAS destruction generally requires more effort and cost because high pressure and/or high heat are required to break the carbon – fluorine (C-F) bonds. A regenerative thermal oxidizer (RTO) or supercritical water oxidation (SCWO) are PFAS destruction methods that can be employed. An RTO typically operates at high temperature (e.g., 1,800 F) and SCWO utilizes both high temperature (>705 F) and high pressure (>3,210 psi) within a process to, again, break the C-F bonds. Electrocoagulation, advanced oxidation processes and plasma are also treatment methods that could be employed to destroy PFAS.
These are just a few of the many PFAS management and destruction options. It can be hard to decide what’s right for your project. That’s where SCS can help. We’re technology agnostic – so you can trust our recommendations are appropriate for your project and goals. Contact us today to learn more about what’s possible.
