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

SmartData SolutionsTM
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/composite samples• Physical features from surface and subsurface

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.

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”.
