By integrating drainage, reinforcement, and separation functions, the design aims to sustain pavement performance under weak subgrades and continuous traffic loading in Northeast India.Project OverviewProject Name: Highway Infrastructure ProjectLocation: Doboka, AssamProducts Used:Ocean Geocomposite 5.5 MM – 500 SQMOcean Geostrap (30–85 kN) – 43,500 MtrOcean Geotextile 150 GSM – 400 ...
Executive Summary LiORA's sensor system for continuous monitoring of hydrocarbon depletion successfully supported regulatory approval for risk-based site management at a historical pipeline spill site in California. Through strategic deployment of soil sensors monitoring temperate, pressure, humidity, C02, CH4, 02, and hydrocarbon concentrations, LiORA provided real-time quantification of ...

Executive summary For a medium-scale retaining wall and adjacent landscaping project in Rewari, Ocean Non Wovens supplied and installed 1,000 square metres of geocomposite drainage/reinforcement material. The geocomposite served three simultaneous purposes: filtration, drainage, and partial reinforcement behind the wall face, allowing a slimmer drainage trench, reducing the need for large stone ...
Floods are one of the most devastating natural disasters in India, causing not just environmental degradation but also massive economic loss. According to the Central Water Commission, India loses nearly ?6,000 crore every year due to floods and river erosion (CWC Annual Report 2022). West Bengal, owing to its extensive riverine network and monsoonal rainfall, is one of the most flood-prone ...
Project Location: Royal Bank of Scotland, Edinburgh, UK Project Details: Hydrostatic and Soil Pressure Relief System Completion Date: May 2003 World Head Quarters of the Royal Bank of Scotland had a clay based soil and fluctuating ground water table complicating project design and delaying construction due concerns regarding the hydrostatic pressure on the concrete ...
Trap & Treat BOS 100 was used to successfully reduce contaminant mass in a localized Trichloroethylene hot spot as part of a pilot test at a former missile site in Nebraska. Over 99% reduction has been achieved in the pilot test well over three and a half years. ...
The health costs stemming from water pollution is up to equivalent of $8.7 billion per year—and the number of lives lost annually in India because of water scarcity, hygiene, and sanitation is around 400,000 people. 2. Depleting Groundwater For most people in India, groundwater is the only source of water, enabling citizens to meet some of their ...
There is also a risk of contaminants seeping from the soil into the water tables and causing a health emergency. Remediating contaminated soil is a must, both to mitigate risks to people in the surrounding areas and to restore the area to its natural state. ...
RSLs aim to protect human health by assessing the risk the contaminants and other stressors pose on humans and ecological receptors. RSL tables are generic, implying that calculations were done without integrating site-specific information. ...
Out of the total world population which happens to be around 7.9 billion, India accounts for 17% of it. The country with such a dense population holds only 4% of the world’s freshwater resources. With 20 basins throughout the country, their average annual water availability is about 1,999.20 billion cubic meters (BCM) as natural runoff. This average figure is dependent on the regions and ...
When high concentrations of naphthalene and methylnaphthalene are present in soil near the ground water table, often the dissolved concentration in the ground water is very low. The accumulation of these compounds at the water table causes a problem for remediation. Frequently after ground water is remediated, seasonal fluctuation of the water ...
Site Summary After the removal of a leaking tank and the surrounding impacted soils, BioLogix microbes were used to treat soils adjacent to a storm sewer pipe contaminated with residual petroleum constituents. The site soils were silty clay fill, formed from excavated and recompacted native tills during the sewer installation. The soil was moist, but the treatment was above the ground water ...
A Vehicle-Mounted Solution Using CrossOver CO730 Customer’s task The Swedish Geological Survey (SGU) has been engaged in groundwater exploration projects to investigate Sweden’s many glacial river deposits. The deposits are spread across the country and are the most significant groundwater resources for drinking water supplies in Sweden. SGU wanted a GPR solution to deploy rapidly to ...
” In the context of hydrogeology, it refers to a natural underground formation of permeable rock or sediment that stores and conducts the groundwater we access through wells and springs. A healthy aquifer not only supplies water, but also helps purify groundwater. ...
Works without harsh chemicals Gur said: “Unlike systems that use harsh chemicals to dissolve scale and corrosion and contribute toxic pollutants to groundwater, the ScaleBuster works without chemicals. Instead, it employs an electrostatic process. ...
Abstract: The proliferation of mine pits that intersect the groundwater table has engendered interest in environmental consequences of the lakes that form after cessation of dewatering. The Getchell Main Pit (GMP) in Nevada hosts arsenic sulfide (AsxSy) mineralization (e.g., orpiment and realar) and ambient groundwater As up to 1.8 mg L-1 , ...
Géomembrane liners are ideal geotechnical products used as the anti-seepage lining system for the tailing dams or ponds to protect the environment and prevent contamination of soils and groundwater tables. BPM textured geomembrane process is a two-step forming method, that is, the roughening of the geomembrane is carried out by blowing and roughening on ...
Florida's average elevation is just 100 feet above sea level, meaning the groundwater table is much closer to the surface than other regions — sometimes it's less than three feet below the surface. ...
The horizontal wells were targeted at 12 feet to 14 feet below ground surface (bgs) which is 4 feet to 6 feet below the groundwater table. Horizontal Well Installation with Directional Drilling: Directional Technologies mobilized to the site in December 2018 to install the horizontal ozone sparge wells. ...
