  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • Soil Sampling under Buildings and Solving Vapor Intrusion using Horizontal Drilling

    The Issue: The New Jersey Department of Environmental Protection (NJDEP) mandated soil and groundwater sampling under an active pharmaceutical company manufacturing building in order to address vapor intrusion inside the building. Installation of vertical borings and wells through the building slab was not practicable without profound disruption of manufacturing activities inside the building. ...

  • Isolate & sample up to 7 zones in one borehole

    CMT Multilevel Systems isolate and monitor up to seven discrete zones in one borehole; monitor 7 zones in the 1.7" (43 mm) System; 3 in the narrow 1.1" (28 mm) System. Both options are low cost. The single tube design makes them fast and easy to drill and install in one day. System flexibility allows port locations and monitoring strategy to be finalized right on site. CMT wells are ideal for ...

  • 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 ...

  • 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 ...

  • Case study - Multilevel sampling and monitoring, Maryland, USA

    Challenges Volatile Organic Compounds contaminated the groundwater posing a risk to nearby private water supply wells. The traditional approach of drilling and sampling multiple boreholes did not provide adequate data to characterize groundwater flow and contaminant migration in the complex fractured bedrock. Solution Westbay System* was installed ...


  • 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 ...

  • 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 ...

  • Case study - EPH in soil evaluation study at tank farm site

    Ambient Engineering, Inc. (Concord, MA) used Sitelab to investigate and remediate a former tank farm along Boston Harbor contaminated by a large, subsurface plume of commingled diesel fuel and No. 6 fuel oil. Ambient’s Licensed Site Professional (LSP) had the opportunity – and budget – to evaluate Sitelab against three certified laboratories. Soil samples were collected from ...

  • Application of Passive Soil Gas Technology to Determine the Source and Extent of A Pce Groundwater Plume in an Urban Environment

    Abstract In situations where groundwater supplies have been impacted by volatile organic compounds, such as perchloroethylene (PCE,) and the source has not been identified, the costs to identify the source and plume migration patterns may be extremely high. The costs for an investigation increase with the number and depth of borings and the number of samples that are collected and analyzed. ...

  • GPR survey to locate USTs and piping at a retail facility

    PROJECT: GPR survey with confirmatory drilling + soil and water sampling / analysis LOCATION: Spokane, Washington PROJECT DESCRIPTION: Designed and performed a tight-line / saturation Ground Penetrating Radar (GPR) survey of an active retail property, to determine the presence, if any, of buried 1950s-vintage underground storage tanks (USTs). Performed ...

  • Field Screening Methods for the Presence of DNAPL, Superfund Site, southern California

    Characterizing the lateral and vertical extent at a Dense Non Aqueous Phase Liquid (DNAPL) impacted site can prove to be a challenging task. Field methods employed to verify the presence of DNAPL have included the use of down-hole Ultraviolet Induced Florescence technologies, the application of down-hole detection materials such as dye impregnated fabrics, and the installation of monitor wells ...
