The 1986 Chernobyl disaster left a legacy of radioactive contamination, rendering vast areas uninhabitable. Traditional remediation methods have struggled to address the persistent radiation effectively. In response, Exlterra developed the Nucleus Separation Passive System (NSPS), a groundbreaking technology designed to expedite the decay of radioactive elements by harnessing natural underground energy. This case study examines the implementation and results of NSPS in the Chernobyl Exclusion Zone. Identifying the problem: Persistent radioactive contamination Decades after the Chernobyl incident, the exclusion zone remains heavily contaminated, with radiation levels expected to persist for thousands of years without intervention. This enduring contamination poses significant environmental and health risks, necessitating an innovative solution capable of accelerating the natural decay process of radioactive isotopes. The NSPS installation: Strategic deployment in the Exclusion Zone Between November 2019 and September 2020, Exlterra, in collaboration with the Ukrainian state agency SSE Ecocentre, installed the NSPS technology over a 1-hectare (2.5-acre) site within the Chernobyl Exclusion Zone. The installation involved placing multiple NSPS units in a precise pattern and at varying depths to create an underground network that facilitates the accelerated decay of radioactive materials. The process was completed without the use of chemicals or the need for soil excavation, ensuring minimal environmental disruption. Results: Significant seduction in radioactivity One year after the NSPS installation, measurements indicated a substantial decrease in radiation levels: Soil Radiation : An average reduction of 46.6% in radionuclides such as Cesium-137 (Cs137), Strontium-90 (Sr90), and Americium-241 (Am241). Air Radiation : An average reduction of 37% in ambient radiation levels. These findings suggest that the NSPS technology can potentially restore the site to its natural radioactivity levels within a five-year period.  The Hemera Project: Watch the video Client reflections: A new hope for Chernobyl Sergiy Kireiev, General Director of SSE Ecocentre, expressed optimism about the project's impact: "These results are remarkable.

Water management on golf courses is a perennial challenge, particularly in regions with fluctuating weather patterns. At Aa Saint-Omer Golf Club in France, areas prone to water stagnation created maintenance difficulties and disrupted play. In September 2020, Exlterra's Groundwater Energy Passive System (GEPS) was installed to address these issues. This case study explores the results of the GEPS installation over two years, highlighting its transformative impact on course maintenance and playability. On golf courses, areas prone to water stagnation create maintenance difficulties and disrupted play Identifying the problem: Stagnant water and limited playability Two areas of the Saint-Omer course—the fairway near the green on hole 5 and a practice bunker—were identified as problem zones. These areas often retained water for days after rainfall, causing soft ground, damage from equipment, and unplayable conditions. Maintenance efforts, including mechanical operations like decompacting and sanding, failed to resolve these challenges effectively. The club needed a long-term solution to improve water infiltration and stabilize the ground. The GEPS installation: Minimal disruption, immediate benefits In September 2020, Exlterra’s professional team completed the GEPS installation in just four days. The process involved inserting GEPS units into the ground in a precise pattern, without the need for network connections or extensive surface disruption. Once installed, the affected areas were reopened for play immediately. According to Aurélie Morandin, Head Greenskeeper at Saint-Omer Golf Club, the installation’s minimal impact on surface conditions was a significant advantage: “The stigmas were almost invisible to the players, and we were able to reopen the game as soon as the drill rig left. This is a very positive point of your system.” Results after year one: Improved infiltration and ground stability Fairway improvements Water infiltration improved significantly, with the system becoming effective within four weeks. Maintenance operations were reduced. The fairway remained firm and playable throughout the year without the need for additional interventions such as sanding or liming. Vehicle traffic on the fairway became manageable even during wet periods, with minimal traces left by equipment. Bunker performance The practice bunker showed slower initial results but began evacuating excess water much faster after heavy rains. Water that previously stagnated for days was now fully drained within half a day after 30mm+ rainfalls. The improved conditions made the bunker usable year-round, enhancing training opportunities for the club’s pro golfers. Results after year two: Resilience during drought The second year of observation presented a contrasting challenge: an unprecedented drought. Temperatures exceeded 40°C (104°F) during the summer, with minimal rainfall recorded in July and August. Despite these conditions, the GEPS-equipped areas performed remarkably well: Fairway performance The GEPS-equipped section of fairway 5 maintained its green, dense vegetation, in stark contrast to adjacent areas suffering from water stress. This result was achieved without supplemental irrigation. Weekly mowing was still required in the GEPS-equipped zone, while other areas of the course saw reduced growth. Bunker efficiency While the practice bunker continued to show some standing water during snowmelt or heavy rains, the volume and duration of water retention were noticeably reduced. The bunker’s year-round usability contributed to consistent player satisfaction and improved training conditions. Environmental and maintenance benefits Reduced maintenance efforts : The GEPS system eliminated the need for additional decompacting, sanding, or fertilization in treated areas. Water resource preservation : By promoting groundwater recharge and reducing the need for irrigation, GEPS supported the club’s sustainability goals.
