2. Subsurface Imaging using DPT Rigs, Sensor Technology and Onsite Analysis Tools Direct Sensing Technology A fundamentally better approach for mapping the subsurface For Brownfields, Property Transfers, NPL sites

3. The Problem • Heterogeneity is the norm • Most investigations are not defensible • Too few samples • Samples are not representative • Sampling error supercedes lab error • Most clean-up efforts fail A much larger number of data points are required to reduce uncertainty.

4. Managing Uncertainty • Managing Uncertainty Approach • Systematic Planning • Real Time Measurements • Dynamic Work Plans • The 7-Step Data Quality Objective Process

5. SmartData SolutionsTM A comprehensive approach integrating recent advances in: • Sensor technology • Rapid computational analysis • Interactive 3D webcasts

6. SmartData SolutionsTM We can now quickly and reliably: • Provide comprehensive images of the subsurface. • Manage uncertainty and assess risk. • Avoid downstream failures and costs. • Monitor remediation performance. • Obtain more cost-effective closure.

7. 3D Image of Solvent Spill Produced from MIP Profiles

8. SmartData - A continuous stream of chemical and physical data, available in a geo-referenced, digital and user-friendly format. Use it for the 3D imaging of subsurface sources, pathways, soil types remediation effectiveness Integration with other site data, such as: Constituent-specific data from discrete samples Physical features from surface and subsurface SmartData SolutionsTM

9. Advantages of SmartData? • Large amounts of geo-referenced, digital data that can be rapidly reviewed, processed, posted and displayed for real time analysis and decision making. • Data that is easily correlated and cross-checked with other data.

10. Types ofSmartData • The MIP/EC Probe for Fuels and Solvents • Membrane Interface Probe/ Electrical Conductivity • MIP/CPT • LIF/UVIF – SCAPS/ROST/FFD for Fuels • Laser Induced or UV Fluorescence +/- MIP • LIF/CPT • Range of Emerging Tools

11. Membrane Interface and Conductivity Probe • For detecting LNAPL, DNAPL,dissolved phase and gas phase VOCs. • For locating sources and plumes in vadose and saturated zones, in sands and clays. • For locating hydrologic and geologic units. • For assessing risk of mass transport. • For monitoring treatment effectiveness

12. MIP Downhole Probe

13. Direct Sensing MIP/EC

14. Multiple Platforms • Direct push rigs • CPT units • Drill rigs • Waterborne • All-terrain track • Indoor – limited access

15. Smarter Sensors Broader Data

16. MIP Response vs Lab

17. Where are you going to sample?

18. SmartData SolutionsTM Investigation Strategy • Use MIP/EC to obtain detailed logs of site. • Generate comprehensive 3-D image. • Then select “more fully representative” discrete samples for analysis. • Make decisions, focus monitoring/treatment and close sites, based on the “whole picture”.

19. MIP results vs water data

20. SmartData SolutionsTMSite Assessment Benefits • Fewer but better sample and monitoring well locations. • Stop endless investigations! • Prevent/limit the big problem sites.

21. 3D Image - Plan View

22. Minimum MIP-PID Response Note the plume appears unbounded at these locations

23. Same Site - plume based on limited lab results DPT Sample Results Color indicates BTEX concentration in ug/L BTEX plume based on DPT results – less resolution

24. SmartData SolutionsTMRisk Assessment • Calculate contaminant mass per hydrogeologic unit • Determine mass available for migration • Determine risk from available mass • Assess monitoring options vs remedial options per hydrogeologic unit

25. SmartData SolutionsTMRisk Assessment Benefits • Provide adequate basis for RBCA. • Remove Regulator’s uncertainty. • Increase confidence in fate and transport modeling with more data density.

26. 3D Image of MIP Data v Well Data

27. SmartData SolutionsTM Remediation Strategy • Use detailed MIP and EC data to assess risk and, if needed, to focus treatment. • Clearly differentiate available mass. • Target units with available mass. • Monitor treatment effectiveness with second MIP survey.

28. Available Mass Assessment

29. Feasibility Assessment Benefits • Understand location of chemicals relative to geology. • Understand pathways and treatment potential. • Treat only if rational. • Focus each treatment.

30. Natural Degradation of Petroleum

31. Value of SmartData SolutionsTM to Expedited Site Characterization The data collected with these tools are: • Of higher resolution, thus fewer interpretive mistakes. • Available immediately, can be used for real-time decision making. • Geo-referenced and digital, so images are created daily for focusing activities.

32. Benefits from using SmartData SolutionsTM • More complete source characterization than traditional phased approach. • Better source and plume delineation in relationship to stratigraphy = more realistic, effective, and targeted remediation. • Net Result: • More realistic planning • Quicker assessments and cleanups • Lower overall project cost

33. A Management Tool for Lowering Costs and Risks A systematic approach for assessing sites that: • Provides accurate image of the subsurface. • Delivers immediate onsite data for direction of site investigation efforts. • Electronic data and webpage makes it is easier to manage - Standard deliverables. • Reduces catastrophic cost and PR exposures • Is more reliable and lowers cost

34. How does SmartData SolutionsTM lower costs? • Reduces time on site and need for revisits. • Reduces need/# of lab samples. • Reduces need/# of monitoring wells. • Expedites reporting. • Provides better documentation for Monitored Natural Attenuation, Technical Impracticability or RCRA based closures.

35. SmartData SolutionsTM helps you win more projects • Allows you to meet tight schedules. • Easier to develop Work Scope. • Provides flexibility to optimize field work. • Greater accuracy reduces mistakes. • 3D images enhances communication and deliverables.

36. Summary • SmartData SolutionsTM Lowers Costs and Increases Success in: • Source area and plume characterization • Migration pathway delineation • Remediation effectiveness • Performance monitoring • Verification sampling With higher resolution data, presented as a comprehensive 3D image of the subsurface, while the teams are still in the field.

37. State-of-the-art SmartData SolutionsTM is a fundamentally better approach that incorporates: • Multiple sensor technologies • Rapid 3D processing • Live interactive webcasts

38. How to turn SmartDataTMinto Smart Decisions The Strategic Use of Data • Data (broader and deeper) • Information (organized data) • Intelligence (processed/analytics) • Knowledge (add human experience) • Consulting (knowledge management) • Intervention (actionable) “Follow the Science”

39.
