Invasive Methods

Abstract

By now the conceptual model has become site-specific with increased details provided by the results from the surface geophysical data. Both background and anomalous conditions have been defined along with their lateral extent. Our focus now shifts to obtaining site-specific geologic details along with engineering, hydrologic and contaminant data. We can now, with a reasonable degree of certainty, develop an effective invasive program and locate direct push measurements, borings, sampling points, trenches and excavations in a logical way so that they provide representative measurements of background and anomalous geologic conditions. Furthermore, by increasing the spatial representativeness of this data, we can obtain sufficient data using fewer invasive measurements.
