The Challenge
80% of the error and uncertainty, therefore the time and cost of site
assessment, cleanup, and long term resolution is directly attributable to a
lack of representative samples

Comparison of 8 Effective K Measurements to 10 Conventional Pump Tests
Potentially Better and More Info For Lower Cost
Average K-Value calculated from Slug Test Results in 10 monitoring wells from the 11-14 meter screened interval 1.5 x 10-3 cm/sec compared to 2.6 x 10-3 cm/sec for HPT
• Consider the cost of well installation and pump tests. • Consider the challenge of isolating individual flow regions. • Consider the impact on site dynamics and remediation costs if you don’t.

Important Final Thoughts • LOE – Use a (Multiple) Lines of Evidence Approach (no one
tool, sampling methodology, or analytical method works in every soil and every situation)
• Measure the heterogenity - Local lithologic changes and local hydraulics control your outcome
• Match the correct detectors to the compounds of concern and know what you are measuring
• Always review performance test before going to the site
• Beware of the statisticians – trying to correlate sample + lab for specific compounds against qualitative screening tools is worse than going to Las Vegas
• Call for expert support prior to planning your field effort

One More Final Thought
It is far better to be approximately correct with a huge data set than precisely wrong with a limited data set.
