  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...

  • Spoil, rubble and a soil-tar mix

    National Grid and Wales and West Utilities recently completed their first joint remediation project at the Aberaman Gasworks following the sale of the Wales and south west of England gas network in 2005. Here Scott Lewis from National Grid and Ashley Griffiths from Wales and West Utilities explain the challenges and processes. The project was undertaken using a stabilisation and solidification ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Case study - EPH in soil with No. 6 fuel oil

    No. 6 fuel oils (heavy fuel oil, bunker C oil) is often used in industry for heat, steam or power generation. A consultant used Sitelab to investigate two different spill sites contaminated with subsurface plumes of NAPL resulting from leaking underground storage tanks (USTs). Soils were collected from borings using a drill rig and field screened for their EPH aromatic content. Split samples ...

  • Soil and groundwater assessment, North-West England

    Project Remediation Strategies were retained to undertake contamination delineation and assessment work at a logistics depot following an accidental release of a large volume of diesel.  An overnight failure in a joint on a pressurised fuel pipeline had resulted in a loss of 15,000 litres of red diesel. Initial response works identified a small proportion of the diesel had ...

  • Case study - EDRO in soil at petroleum tank farm site

    Environmental engineers needed quick and accurate screening analysis on a tank farm contaminated with a subsurface plume of fuel oil. Sitelab's EDRO test was performed to delineate the vertical extent of contamination. A drill rig was used to collect samples from the surface down to twenty feet at different locations throughout the property. They needed to quantify the size of the NAPL plume in ...

  • Physical Modeling of Drilled Shaft Side Resistance in Sand

    Dimensional analysis of deep foundation side resistance is used to formulate the laws of similitude for drilled shaft uplift capacity. The resulting prediction equation for dimensionless side resistance then is tested against the results of static uplift load tests on model drilled shaft foundations in sand constructed at three different scales, all satisfying the same conditions of similitude. ...

  • Sled for In Situ Penetration Testing

    In situ testing devices such as the dilatometer, the piezocone, the pressuremeter, and the field vane generally require the use of a drill rig for penetration through soils. This paper describes a multipurpose portable pushing frame built at the University of New Hampshire and designed to be used with most in situ testing probes. This rig is compact, inexpensive, easy to use, and can operate on ...

  • Time-Tested Advantages of Horizontal Wells

    Wells are wells are wells, right? Both conventional vertical wells and directionally drilled horizontal wells have a screened casing that is connected to solid riser casing which leads to the ground surface. Groundwater or soil vapor is drawn through a well screen to remove contaminants. Remediation agents such as air, bioamendmnents or potassium permanganate are injected through a well screen to ...

  • Arsenic wood field testing kit

    Now available from Industrial Test Systems, Inc. is a quick, easy, field test kit that can confirm the presence of inorganic arsenic in wood. Arsenic Quick™ 481396-W kit is a modification of the US Patented, ETV Verified arsenic test for drinking water. This 10 minute test readily confirms the absence or presence of arsenic in any wood sample, including CCA treated lumber using safe ...

  • Effects of Borehole Fluid on Standard Penetration Test Results

    The standard penetration test (SPT) represents the most widely used in-situ test method for evaluating the liquefaction resistance of saturated soils. Significant progress has been made in recent years in developing correlations between SPT results obtained using different test procedures and equipment in order to develop a higher degree of standardization for SPT testing. One of the heretofore ...

  • Getting ahead of the Caribou - pitdry process—innovative solidification solution for spent drilling fluids

    An oil company has been producing oil and gas in British Columbia’s Southern Foothills since 1992. The operator has continuously invested in the area and recently opened up new gas producing wells northwest of Fort St John, the largest city in the northeast region of British Columbia. The new wells are situated 4,600 feet above sea level in a rigid mountain terrain. The viable way to connect the ...

  • Small Diameter Piston Sampling with Cone Penetrometer Equipment

    A small diameter piston sampler that can be operated by a cone penetrometer rig has been developed specifically for recovery of sand and clay samples under conditions where sample recovery using ordinary means is difficult. The 22-mm-diameter sample that is recovered in a polythene sheath is valuable for visual examination of the soil rather than for most laboratory testing purposes. Provided the ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...
