Do Leachate Better
Over 10 million Gallons Phyto'd
Phyto Vetiver Project
Gulf Pines Landfill
2011 - Present
This small but mighty 3 acre Phyto plot has successfully operated since 2011, processing more than 10 million gallons. The system won a National Engineering Excellence "Grand Award" for First Place in its category at the American Academy of Environmental Engineers National Banquet in Washington, DC. As stated in an article written in the MSW Management magazine, the award was based on "originality, innovation, complexity, project quality, client satisfaction, contribution to social and economic advancement, and an integrated approach to better protect the environment."
Phyto Poplar Project
Mallard North Landfill
2018 - Present Hanover Park, Illinois
The Mallard North Landfill is our largest Phyto-Utilization™ system to date, covering nearly 15 acres of the closed landfill. Since operation began, the system has processed over 18 million gallons of leachate with flow as high as 25,000 gallons per day. The system is reducing the facility’s carbon footprint by sequestering CO2 and creating significant long-term savings for the facility and habitat for wildlife.

Foam Fractional PFAS Removal
LMS and The Water and Carbon Group (WCG) have completed dozens of on-site demonstrations of the LEEF System® for PFAS removal with numerous landfill leachates. Its specialized foam fractionation process directly removes PFAS from raw, untreated leachate and wastewater. The leachates had vastly different contaminant characteristics, including a couple of Reverse Osmosis concentrates.

Consistently removed PFAS from raw leachate to below lab detection limits as low as < 4 ppt!

WAIV Evaporation N.A. Pilot Testing & Predictability Refinement
Predictable Lowest O&M Evap
2019 - Present WAIV is FULLY Ready for Market in 2023
WAIV® can operate in a variety of climates, including humid areas. Its performance is directly correlated with the pan evaporation rate, which is determined by numerous parameters such as humidity, temperature, wind, solar radiation, and precipitation. The technology has been proven through previous project efforts in Israel, Mexico, and Australia, showing typical evaporation more than ten times (10x) the volume of evaporation ponds based on footprint area.
To demonstrate the capability of WAIV in the US, LMS developed a mobile, pilot-scale unit in collaboration with the technology’s inventors to test at sites across the country and to validate the sophisticated modeling that is used during the design process.
The pilot system consists of a soft-sided trailer and approximately 3,300 ft2 of evaporative surface area, just under 5% of a single full-sized WAIV unit. Weather and performance data parameters are collected for each pilot test. Evaporation from a WAIV system is directly proportional to evaporative surface area, so scale-up from a pilot system to a full system can be done with confidence.
A Single WAIV can Evaporate Between 800K - 2.2M Gallons Per Year. Gen 3 Looks like at least a 50% Increase

15,000 GPD Treated & Reuse of Over 500,000 Tires
Wetland System with Tire Berm
Pine Ridge Landfill
2020 - Present
A constructed wetland treatment system was constructed at the landfill to treat up to 15,000 gallons per day of leachate. The liquid is pumped to an aerated pond, followed by an aerated nitrification wetland, then to a tertiary polishing wetland. The process flow was designed to effectively remove ammonia, organics, and suspended solids from the leachate.
To ensure long-term operation and protection against extreme weather events, key innovative design techniques were applied. The wetland was constructed using a unique berm structure to an elevation higher than the normal hurricane flood level for the area. Specifically, the berm consists of approximately 500,000 waste tires and aggregate mixed together under a secured liner system. The use of waste tires as berm material for a wetland is an unprecedented way to reuse the tires that would have otherwise been shredded and disposed in the landfill or end up in the ocean during flood events. The wetland was also designed with breakwater structures and surge inlets. These berm design considerations proved successful by remaining intact as Hurricane Dorian caused massive destruction to the islands in September 2019.
The system is operating well and effectively treating the leachate.
Leachate Scaling Project
Indiana MSW Landfill
2019 - Present Indiana
The MSW landfill had been experiencing increased precipitation of leachate scale throughout areas of the collection system and sump pumps. Formation of scaling is becoming more rapid and has reached problematic stage. Jetting is a constant battle to keep leachate flow with chemical de-scalers being a pricey option. It was a Tuesday that I saw an article on Linkedin about a “breakthrough technology for leachate scale control”. The system used a charge to treatment pads on the outside of pipes and pumps and was guaranteed to not only inhibit but also remove leachate scaling. Attaching to 2 pumps that had to be cleaned almost weekly and 3 scaled lines that were in need of cleaning more frequently; they saw results in the first week. Wells and sumps were gathering a slurry and chunks of scale (much like after jetting) and the pumps look like new after many months of operation in the sumps
Over $200K Annual in Savings
6 Million Gallons and Still Going
PHYTO Vetiver Project
Woodland Hills Landfill
2014 - present Louisiana
The Woodland Hills project has been a success since its installation in 2014, processing more than 6 million gallons of leachate and the plants always look great! The system has reduced the facility’s carbon footprint by sequestering CO2 and avoiding tanker truck emissions, as well as created significant long-term savings for the facility and habitat for wildlife
Hydrogen Sulfide Removal
2015 - Present Tennessee
In April 2015, a solid waste company approached LMS with a high priority dilemma. One of their construction and demolition (C&D) landfills in Tennessee had been disposing of its leachate through a direct discharge permit with a local WWTP; however, recent H₂S odors caused the WWTP to restrict the landfill’s volume and threaten complete cut-off if the problem wasn’t resolved.
LMS quickly coordinated a bench scale test to determine potential H₂S treatment solutions. Aeration and hydrogen peroxide were identified as successful options, and a pilot test was completed on-site to verify the findings. It was concluded that a combination of aeration and chemical oxidation using hydrogen peroxide was the best solution for the facility.
During final design of the treatment system, LMS and the landfill worked closely with the WWTP to update them on the plans and to agree on permit conditions. By June 2016, the treatment system was installed and testing was underway. The WWTP managers were invited to the landfill to see the new system and observe full-scale operation. After a successful trial period, the WWTP approved the new permit and direct discharge was reestablished.
Since operation began, the system has treated more than 6.8 million gallons of leachate for the facility.
