Definitions

  • the present invention relates to characterization of contaminated waste disposal sites and, more particularly, to real time analysis and monitoring prior to and during remediation treatment, of hazardous and/or radioactive waste contaminant levels and treatment progress.
  • site is intended in its broadest sense to include, but not be limited to, open and closed landfills, spill sites and even closed storage containers.

  • the invention involves placement of downhole probes which detect contaminants and monitor treatment progress and unique methods of subsurface working of contaminated soil with reduced motor torque loading as compared with the methods and apparatus known heretofore.
  • Various types of probes, not critical to the broadest aspects of the invention are disclosed.
  • the invention in its broadest aspects, provides a method of identifying hazardous waste in a subsurface soil site comprising the steps of: a) positioning contaminant sensing means proximate a sensing end of a non- rotatable drill casing having a first diameter; b) boring a hole into the hazardous site using a rotary drill comprising a rotary kelly bar and a drilling section affixed to said kelly bar which creates a hole of a second diameter larger than said first diameter; c) longitudinally inserting said sensing end of said non-rotatable casing and contaminant sensing means into said hole while boring said hole; and d) using said contaminant sensing means to sense the presence and composition of soil contaminants encountered during said boring of said hole while logging the characteristics of said contaminants and the locations at which they were encountered.

  • the kelly bar 10 ordinarily has a cross-section of non- circular configuration (Fig. 3) so that it can be driven by a conventional top drive motor 20.
  • the kelly bar 10 is preferably hollow and its internal passageway 11 seen in Figure 3 comprises a dual purpose conduit for either removing vaporized or gaseous materials from soil gas inlet ports 13 which extend through the wall of the drill bit to the hollow interior thereof, the ports 13 being located at a subsurface location proximate the drilling section bit 12 to pass soil gas upwardly through the kelly bar 10 to a fluid swivel 22 located above the top drive motor 20 or for downwardly conveying treatment reagents to be injected through reagent injection ports 14 (Fig. 2).

  • the surface equipment typically includes a vacuum pump 23 to assist gas removal, and gas analytical devices 24.
  • Ports 13 and 14 are located proximate the drilling section and, as referred to herein, the term "proximate the drilling section" is intended to mean that the ports are disposed in the general zone of mixing of materials by the cutters or bit or slightly thereabove such that gases may be conveyed upwardly via the ports 13 and preferably through hollow kelly bar passageway 11 to the surface where they may be physically analyzed and, if desired, so that treatment reagents may be delivered downwardly through the kelly bar passageway 11 and ports 14 to soil at essentially the same elevation.
  • a port blinder shield 16 is welded in the region shown to the kelly bar 10 or drill bit 12 as the case may be, directly leading the soil gas inlet ports 13 in direction of rotation to prevent or minimize clogging of the ports 13 with the churned soil as it flows over the ports 13.

  • the top drive motor 20 is rigidly affixed to the vertically moveable support 33 and is bolted or otherwise connected to a welded flange 31 on the upper end of casing 30 to support casing 30 during movement thereof vertically into and out of the ground.
  • the radial extent of the blades 12a of drilling bit 12 is at least slightly greater than the diameter of the casing 30 such that the drill bit 12 creates a bore of sufficient size to accommodate the casing 30 and an optical probe or multiple probes 40 at the lower end of the casing 30 and attached fiber optic cable 44 removably affixed to the exterior of the casing 30 by suitable means such as by welding.
  • the probe 40 could be mounted instead in the inside of the casing 30 as seen in Figure 3 provided that a sufficient annular clearance space 42 is provided for the rotating kelly bar 10.
  • Either external or internal mounted probes or both can of course be utilized in selected applications although it is presently contemplated that the external mounting is preferred since internally mounted probes are comparatively inaccessible and would require modification of the bearings 32 between the casing 30 and rotating kelly bar 10 to accommodate the probe 40 and a fiber optic cable 44 leading therefrom to the surface location.
  • probe 40 shown in Figure 4 comprises a rigid protective probe housing 50 having an open exposed sample window 52 extending through the peripheral wall thereof near the lower end of the probe.
  • Fig. 5 shows an optical tube 60 of generally cylindrical configuration used for fiber optic positioning which is slideably mounted inside the probe housing 50.
  • the tube 60 has a plurality of optical fibers 62 wound therearound which are preferably arranged in separate spaced horizontal layers 62a - 62g laid in protective grooves extending circumferentially around the tube 60.
  • Each fiber 62 has an optical gap 65, which may be of various sizes, therein between first and second ends 63, 64 which extend upwardly to a multi-fiber optic coupling 70 which binds the individual fibers into the fiber optic cable 44 which extends upwardly from the probe housing 50 to the surface elevation proximate the drive motor 20 as seen in Figure 2.
  • the optical tube 60 is removable from the probe housing 50 as a unit for replacement as the optical fibers 62 become chemically exposed or damaged and are no longer reliable for further use.
  • Means are provided for moving individual fibers and their optical gaps 65 into operative proximity with the sample window 52 in the probe housing 50.
  • Figure 4 shows separate vertical positioning and rotational positioning motors 74, 76 and electrical leads 78 for moving the individual fibers and gaps 65 therein toward and away from the window 52 either by vertically moving the tube 60 or by rotating the tube relative to the window 52.
  • the individual fibers 62 may be arranged axially of the tube as will be seen below in an optical casing embodiment described with reference to Fig. 6, rather than circumferentially thereof in which instance the tube rotating motor 76 is employed to properly position one or more fibers and gaps 65 proximate the sample window 52.
  • the mechanical connections of the motors 74 and/or 76 to the tube 60 will be readily apparent to those skilled in the art.
  • one means of flushing the probe window 52 and the optical fibers and gaps 65 comprises a fluid pump 79 (preferably water) and a fluid jetting tube 77 extending on the exterior of drill casing 30 down to the probe housing 50 where it is placed in fluid communication with an annularly extending cleaning chamber 53 in the wall of the probe housing 50.
  • FIG. 6 a modified embodiment of the invention employing an optical casing 80 mounted inside the casing 30 for movement relative thereto is disclosed.
  • the optical casing 80 is disposed in annular clearance space 42 (Fig. 3) between the rotating kelly bar 10 and the non-rotating casing 30 and comprises an elongated tube having a plurality of discrete optical fibers 62 axially wound therearound with optical gaps 65 on the exterior surface of the optical casing 80 at an elevation proximate the drill bit 12 or mixing blades so that the individual optical gaps 65 can be selectively aligned with a sampling port 52 extending through the drill casing 30.
  • the individual ends of the various optical fibers 62 are bundled together as was described with reference to Fig. 5 into a fiber optic cable 72 and an electric or pressure driven motor 84 and drive wheel 86 is shown for rotating the optical casing 80 relative to the drill casing 30 and sampling port 52 therein.
  • the fibers are recessed in the exterior anular surface of optical casing 80 to prevent damage by the drive wheel 86.
  • a solid soil core sampling apparatus is optionally provided inside the hollow kelly bar 10 inside the casing 30 as seen in Figures 7a - 7d.
  • the solid soil sampling apparatus comprises a generally conical drive point 90 slideably mounted inside a circular kelly bar bore 11 which also serves as a soil sample core barrel. If desired, a separate core barrel liner (not shown) may be used in the kelly bar 10.
  • the drive point 90 is affixed to a linear actuator 92 such as a hydraulic cylinder/piston arrangement controllable from the surface location.
  • the actuator 92 is initially in a fully extended position and the top drive motor 20, non-rotatable casing 30 and actuator 92 are then moved together downwardly at the rate of boring.
  • the drive point 90 is thus moved downwardly with the coring bit 12 to a selected elevation A (which is a fixed distance depending upon the selected length of the core sample) above the subsurface elevation B from which the soil sample is taken.
  • the linear actuator 92 retracts as it holds the core point 90 at this elevation A during further penetration of the earth by the coring bit 12 during which time the soil sample automatically enters the kelly bar/core barrel as seen in Figure 7b.
  • the kelly bar 10 casing 30 and solid soil sample retained therein is withdrawn from the subsurface as seen in Figure 7c and is positioned above a soil sample retainer 94 following which the linear actuator 92 is extended forcing the conical sample point 90 to eject the sample or portions thereof from the kelly bar/core barrel directly into receptacles 96 in the sample retainer 94 without human handling or exposure of the sample to the ambient atmosphere (Fig. 7d) thereby preventing release of soil gas from the core sample.
  • the sample may be separated into discrete sections and frozen in the various receptacles 96.
  • each optical fiber 62 is energized by a light source 110 shown schematically in Fig. 5 such that the light is conducted through a multiplexer 111 by the fiber to and across the optical gap 65 therein and is subsequently returned via the multiplexer 111 to a spectroscopic analyzer 112.
  • spectroscopic analyzer is intended to comprise a general term for analytical instruments including photodetectors such as spectrographs, spectrometers and the like which analyze light patterns and the modulation thereof by vapors or gases entering the optical gap 65 to determine the composition and/or concentration of fluids present in the optical gap 65.
  • the optical gap may be a transmissive gap or a reflective gap or, in general, any optical gap between the ends of a transmissive optical fiber 62 of dimensions suitable for analyzing contaminants.
  • the invention comprises means for delivering analytical equipment to and retrieving analytical equipment from a subsurface location and for retrieving data therefrom
  • the analysis is intended primarily to comprise the "eyes and ears" of hazardous waste detection and treatment during a soil remediation process. Therefore, as seen in Figure 8 the drill bit 12 may take the configuration of a solid elongated mixing bit 120 having a plurality of evenly radially distributed hollow blades 122 each provided with injection ports 123 for dispersing hot air, steam or treatment reagents into contaminated sites to be remediated.
  • Reagents to be injected are conveyed downwardly through the interior passageway 11 of hollow kelly bar 10 and elongate inte al passageways 124 in or upon the mixing blades 122 for ejection at the ports 123.
  • Reagents to be injected are conveyed from suitable surface located extemal sources 125 through fluid supply tubing 126 which enters the upper stationary portion of fluid swivel 22 which has its lower rotatable portion rigidly affixed to the upper end of the kelly bar 10 whereby the reagents will be conveyed downwardly through the intemal passageway 11 of the kelly bar 10 to the elevation of the mixing bit 120.
  • reagents from source 125 may be directed by a pump 128 and conduit 129 mounted exteriorly on casing 30 to a discharge nozzle located at the elevation of the drill bit 120.
  • the device comprises a rotatable kelly bar 10 with a top drive motor 20 and multi-port fluid swivel 22 which receives treatment reagents from suitable extemal supplies. Fluid reagents under high pressure are conveyed from source 125 via pump 128 and swivel 22 downwardly through the kelly bar 10 to the treatment elevation at which the drilling section includes radially directed high pressure jet nozzles 131 and a folding underreamer 120 attached to the kelly bar 10.
  • the underreamer 120 can be radially deployed at the desired treatment elevation. Deployment can be gradual as the underreamer 120 is repeatedly moved between two vertically spaced locations to create a moveable waste treatment zone. Gradual deployment of the underreamer 120 results in significantly reduced motor torque requirements as remediation takes place.
  • linear actuators such as hydraulic piston/cylinder units 132 are actuated to extend the underreamer 120 by downwardly pushing a cap 134 and non- rotatable casing in the form of an actuator tube 136 which is positioned above the rotatable underreamer 120 for increasing the radial extent of the underreamer 120 for treatment.
  • the high pressure jetting of treatment reagents assists in deployment of the underreamer 120.
  • Soil is treated vertically and horizontally by increasing or decreasing the radial extent of the underreamer 120.
  • One or more optical probes 40 as described above may be affixed to the exterior of the non-rotatable actuator tube 136 which is the mechanical equivalent of the casing 30 shown in the embodiment which does not use an underreamer.
  • the drilling section embodiment shown in Figs. 10 - 12 is a fixed blade cutter arrangement instead of a folding underreamer as described previously.
  • Two vertically spaced sets of cutter blades 140, 142 each having fluid conduits 144, 146 therein are mounted on the lower end of the kelly bar proximate the lower sensing end of casing 30.
  • the lower set of blades 140 carries contaminant treatment fluid conduits 144 which terminate in a plurality of injection nozzles 145.
  • the upper set of blades 142 carries the conduits 146 for removing volatilized contaminants from the waste treatment zone.
  • Each set of conduits 144, 146 separately continues and extends upwardly through the kelly bar as seen in Fig.
  • treatment fluid is intended in its broadest sense to include, but not be limited to, e.g. heated fluids such as steam or hot air, wet and flowable dry granulated chemical or biological reagents and microbes, biological nutrients and the like.
  • a typical hazardous waste disposal site remediation is a complex operation involving repeated analysis and remediation steps. With the present invention, these steps need not be intermittent and instead are simultaneous—i.e., in real time during a single drilling stage.
  • analytical data is continually transmitted to the analyzing apparatus 112 at the surface which is combined with 3-D mapping of the contamination profile and remediation progress of the contaminated site.
  • Optical sampling as well as gas sampling can be conducted simultaneously.
  • the injection of suitable remediation agents can be varied as necessary depending upon the sensed conditions whereby remediation of non-contaminated areas can be prevented or minimized and the most efficient use of the required treatment reagents without exceeding the necessary volumes thereof for effective treatment can be carefully controlled to result in the most economical treatment of a site.
  • the intemal passageway 11 of the kelly bar 10 When the intemal passageway 11 of the kelly bar 10 is not being used for delivery of treatment reagents it can be used to retrieve soil gases to the surface elevation where physical analysis of the gas may be used as a cross check to validate the data simultaneously obtained by the optical analysis.
  • a confined space or enclosure is created in the area immediately surrounding the borehole by a gas and vapor impermeable shroud or process module 140 having its interior maintained under subatmospheric pressure so that contaminant vapors and gases escaping from the borehole are immediately decontaminated by scmbbers mounted on the process module 140 and do not contaminate the atmosphere or endanger personnel at the site.
