  • A high level of project uncertainty in the data or the evaluation used to make critical decisions can be devastating to ultimate project success. For example-underestimating aerial extent of contamination can significantly skew remedial cost estimates, contaminant risks and project liability. Thus, a remedy will be selected upon erroneous assumptions and significant cost overruns and schedule slippage can occur. TRIAD Approach minimizes project uncertainty by allowing a more complete characterization on an expedited basis for a reduces costs when compared to comprehensive conventional sampling. Systematic and Dynamic Work Planning Strategies allows for flexibility in field implementation creating an opportunity for continually optimizing your sampling plan to obtain complete characterization within one field event. Real-time measurement requires daily interpretation of data and adjustment of the sampling schedule based upon this data. Complete characterization can be obtain with a significant reduction in sampling when data is evaluated daily during field investigation activities.
  • Some of the Critical Components of Success of a TRIAD Approach is the Accurate interpretation of real-time data Use of lines of evidence in evaluation of the daily data. For example, if the ECD indicates a silty peat layer and the FID records a response, this response may be due to methane generation from biological activity and not a site related constituent. These detectors response to all straight chain and polyaromatic hydrocarbons as well as chlorinated substances and not just ones on the TCL list. The most critical component to successful implementation of the TRIAD is to ensure that your confirmatory samples are properly selected to confirm plume geometry.
  • Since the end use of the data is to determine potential risk to receptors and determine a remedy if required, chemical speciation is critical to support these evaluations. Chemical Toxicity is species dependant and so is treatment methods. Therefore to accurate assess the risk and overall vol/mass of removal required, exact chemical makeup of the plume is required. In order to establish a database that is most representative of site conditions, confirmatory sampling should be collected not only at the hot spot or source zone, but also the core and distal zone of the plume to provide an accurate assessment of degradation with distance. Thus, the geometry of the plume should be characterized with the confirmatory sampling which is guided by the MIP responses.
  • As you can see the FID has minimal response as compared to baseline except a small response at around 20 feet The PID also has minimal response except at a depth of 20 feet. The ECD however has a fairly large response at a depth of 10 feet (which corresponds to a perched water table at this site-former recycling facility). You can also see a layer of higher permeability that begins at this same location These continuous logs facilitate the development of a site conceptual model Prior to each borehole a Pre log response test is run to assess the condition of the membrane. With each borehole, the membrane gets a little more saturated with contamination so you want to make sure the membrane is still responsive to a test solution A post run log is also run so that membrane saturation can be identified and the membrane can be changed
  • These are the MIP detection limits on several key compounds. Thus, if you are delineating a plume where the source zone is less than 250 ppb, the MIP will not help you further define the plume. In order for MIP application to be practical, a fairly elevated source area would need to exist.
  • Now we will move on to the Case Study of the Former Recycling Facility located in Queens NY This site was a former recycling facility that transported materials via rail. Here is the still active portion of the rail line and here is the location of the former rail spur that tranported material to and from the site. The back of the building and the back of the site was utilized for material handling The site is currently being use as an active lumber yard. The adjacent site is a petroleum spill site and chlorinated solvents were detected entering the site. The inactive rail spur separated the properties and ran between the two adjacent buildings. In order to prove that the chlorinated solvent contamination was coming from the upgradient former recycling property three transect lines of MIP sampling was proposed.

  • Here is a 3D animation of the plume extending from the dry well in the northern portion thru the potential spill area of the truck entrance and south to the rail bay loading entrance. As you can see, the upgradient, downgradient, and side gradient directions of this plume has been delineated within one mobilization. Confirmatory sampling has occurred in the appropriate zones (source, core and distal zones) to support the development of future assessment of risk and remedy selection and design In addition to this case study demonstrating the successful implementation of the TRIAD approach utilizing the MIP, my associate Jessica Beattie will now discuss MIP implementation at a former Dry cleaning facility in Westbury NY.

  • The MIP collected continuous data down to a depth of approximately 20 feet. The MIP characterized nicely the three source areas and their relative concentration. Confirmatory sampling was selected from Source Zone Core Zone Distal Zone (including upgradient, downgradient and side gradient) To confirm plume geometry This will allow for an accurate assessment of site risks as well as vol/mass of contaminant for support of the remedy selection and design

    • Brownfields have been defined as underused or abandoned properties often located in urban and economically distressed areas that may contain environmental contamination.
    • 425,000 brownfield sites in the United States
    • Remediation, redevelopment, and reuse of these properties have been discouraged by real or perceived environmental contamination
    • State and federal Brownfields funding as well as liability limitation has spurred the redevelopment of these impaired sites nationwide.

  • 12. Site Background
    • An 85-acre municipal landfill is located within a 200- acre brownfield development area (BDA).
    • The BDA consists of eight abandoned brownfield sites along 2 miles of the New Jersey shoreline along the Delaware River, overlooking the Philadelphia skyline and within a highly urbanized area of New Jersey.
    • The unlined landfill operated from 1952 until
    • An area of industrial chemical waste material saturated with chlorobenzene (CB) and dichlorobenzenes (DCB) was identified in the southeast portion of the landfill.
    • This material is approximately 20 to 30 feet below ground surface (bgs) and acts as a continuing source of groundwater contamination and localized soil vapor contamination.

    • MIP fuel was switched from diesel to biodiesel, which is a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel is biodegradable, nontoxic, and essentially free of sulfur and aromatics (NBB, 2009).
    • The MIP, Geoprobe® track unit, and support vehicles used 5-percent biodiesel as their main fuel. The project also involved the replacement of all petroleum-based hydraulic fluids with bio-hydraulic fluids. These are non-hazardous, high-performance, hydraulic fluids engineered as drop-in replacements for petroleum-based hydraulic fluid formulas.
    • Using the TRIAD approach, we were able to expedite characterization with fewer borings. Instead of having to grid the site with borings, we were able to target specific sampling locations and depths using real-time data. We completed full delineation of the source area within a 6-week field program as opposed to several phased investigations extending over several months to years.
  • 28. CONCLUSIONS
    • The use of the MIP as part of a TRIAD approach was proven an effective tool for horizontal and vertical delineation of hot spots and source areas at the landfill. The real-time data allowed placement of screening and sampling points more effectively, and resulted in a well-defined source areas to be further analyzed for remedial feasibility
    • Because of detector sensitivity limitations, the MIP may not be appropriate at all sites. The tool is geared toward sites with known contamination at concentrations above detection limits. In this investigation, it was critical that the temperature be maintained above 132ºC (boiling point of CB) in order that it would volatilize and be detected by the ECD. The MIP contributed to meeting sustainability objectives for the project, and overall project objectives were met on an expedited basis due to real-time field measurements and dynamic work strategies.
    • Reduction of the investigation’s carbon footprint included using biodiesel, decreasing the amount of IDW produced from soil and groundwater sampling (e.g., bottleware, shipping materials, and decontamination fluids), by only collecting confirmatory samples, and requiring one mobilization and demobilization. This was aided by streamlining the investigation using real-time screening data during the TRIAD approach.
