DRILL GUIDE Overview
DRILL GUIDE's capabilities to grid and interpolate sparse measured data in three dimensions are unparalleled. DRILL GUIDE performs all interpolation
using an accurate and geostatistically-defensible process called kriging. Kriging is a mathematical process recognized by the U.S. Environmental Protection Agency (EPA) as the best and standard means for
interpolation and extrapolation of measured data. DRILL GUIDE provides a user-friendly expert system to drive its Kriging modules, lifting the burden of determining optimal variogram parameters from the user. With
DRILL GUIDE, the user can rely on expert system calculated default values to provide quality answers in minimal time.
Kriging is the only data estimation method that also provides statistical measures of goodness. When data is analyzed in DRILL GUIDE, the user is
also provided statistical confidence and an additional parameter that we call uncertainty. These additional statistical measures are extremely useful in guiding future site investigation efforts. Our experience is
that by using maximum uncertainty to guide environmental site investigations, a 30% reduction in sampling locations can be realized for an equivalent quality of assessment.
