Introduction
DOE and EPA DQO Mission:


Make defensible decisions by managing
uncertainty via systematic planning
Institutionalize the standardized Data Quality
Objectives (DQO) Process (systematic
planning) throughout the EPA Regions and the
Department of Energy (DOE) complex

Day 2 Course Objectives

Learn
– “How to” for each activity in steps 1- 4 of the
DQO Process
– Basic statistical concepts using hands-on examples
and computer simulations
– How to manage uncertainty in the sampling and
analysis design process
