    1. 1. CSME/SARCLE, ENSIC Nancy, October 22-24, 2012Session 1: Tools for Defining Impacts and Liabilities Validation of an On-Site Component- Specific Detection Method for Volatile Organic Components: EnISSA-MIP Pieter Buffel (pieter.buffel@enissa.com); Wouter Vandeputte; Samuel Van Herreweghe; Wim Vansina and Mark Van Straaten (EnISSA – MAVA, BELGIUM) B. Van Goidsenhoven (bert.van.goidsenhoven@ovam.be); Inge De Vrieze and Veerle Labeeuw (OVAM, The Public Waste Agency of Flanders, BELGIUM)

    3. 3. 1. Introduction improve the quality and minimize the pollution of soil and groundwater by developing an integrated approach to tackle the threats caused by contamination with chlorinated solvents in urban areas.9 partners from Flanders, Netherlands, France, Germany Lead partner: OVAM The Public Waste Agency of Flanders, Belgium www.enissa.com www.enissa.com
    4. 4. 1. IntroductionResearch budget 5.2 M€ (50% funded by Interreg IV NWE project)Focus on: - Social-economical aspects - Remediation techniques - Characterisation techniques Pilot project 2: Validation & demonstration of an innovative site characterisation tool www.enissa.com www.enissa.com
    5. 5. 2. MIP Membrane Interface Probe  Screening tool for VOC  Cone: heated block and hydrophobic semi permeable membrane  Direct push  Local heating of soil  Volatilization and diffusion through membrane  Inert carrier gas & transport to detector Typical setup: Combination of three detectors: * Dry electrolytic detector (DELCD) or Halogen specific detector (XSD) * Photo ionisation detector (PID) * Flame ionisation detector (FID) www.enissa.com www.enissa.com
    6. 6. 2. MIP  EnISSA MIP PID, FID, DELCD & XSD → Summation-detectors: no information on individual contaminants: polluent cocktails! → respons is component specific  quantification difficult → detection limit > groundwater clean-up values in Flanders : μg/l EnISSA MIP• MIP with dedicated GC-MS detection combined with proprietary contaminant sampling technology• GC-MS: Optimized for field measurements: * ruggedized * cycle/analysis time: 1 min  1 measurement per 30 cm at probing speed of 30 cm/min * up to 12 compounds simultaneously Highly detailed profiles for individual compounds on ppb level www.enissa.com www.enissa.com

Pilot Study Field resultsSite description:* Location: Kortrijk (Belgium)* Former spinning and weaving mill* Contaminants: CVOC & BTEX* Three sources, possible DNAPLPurpose: Validation of the EnISSA MIP by traditional samplingMIP configuration:MIP Controller Model MP6505 / Field Instrument Model FI600040 m unheated Teflon-Peek trunkline35 ml/min N2 flow www.enissa.com www.enissa.com
    9. 9. 3. Field results: EnISSA MIP 10004 EnISSA  detailed soil profiles for individual compounds * low detection limit www.enissa.com www.enissa.com * each 30 cm or less: characterization of up to 12 compounds

    12. 12. 3. Field results: Source area• EnISSA gives a soil/ground water profile for each component: •  profile confirmed by soil & groundwater samples•EnISSA gives indication of presence of DNAPL: •  visually determined during ground water sampling  soil & groundwater samples also indicate presence of DNAPL•EnISSA concentrations correlate with groundwater concentrations:  remarks: ! EnISSA measures soil, groundwater & pure product phase ! EnISSA is calibrated with aqueous solution www.enissa.com www.enissa.com
    13. 13. 3. Field results: Plume area: DCE Inaccurate filter location! www.enissa.com www.enissa.com
    14. 14. 3. Field results * contribution of the adsorbed contaminants which will be measured by EnISSA but not by the groundwater samples * EnISSA results vs. groundwater results: order of magnitude is comparable  semi-quantitative www.enissa.com www.enissa.com

    18. 18. 5. Conclusionsentire delineation of contamination: source + plume EnISSA MIP measures on ppb level → source and plume (Conventional MIP measures on sub-ppm level) - Order of magnitude = groundwater sample  high quality screening tool -“On site” information on pollution cocktails: EnISSA MIP measures individual compounds in contrast to the sum-detectors used in conventional MIP - Each 30 cm up to 12 compounds can be distinguished -strategic sampling well locations: The entire delineation of source and plume obtained by EnISSA MIP makes it possible to place sampling wells at strategic locations reducing sampling costs and time. www.enissa.com www.enissa.com
