8:00
am - 8:10 am Module
0: Introduction and Opening Remarks
Presenter: Sebastian Tindall
This module briefly discusses the mission to institutionalize
the DQO Process throughout the DOE complex and provides an
overview and the objectives of the workshop. Also, this module
presents the day's agenda. |

am - 8:40 am Module
1: How many samples do I need?
Presenter: Sebastian Tindall
Sampling and analysis methods are used to estimate the
true condition of site. However, estimation introduces uncertainty
into the decision-making process. This uncertainty can be
managed through planning so that you can "do it and prove
it" efficiently and effectively. |

8:40
am - 9:30 am Module
2: Key Concepts Underlying DQOs and VSP
Presenter: Sebastian Tindall
Using innovative, interactive demonstrations, the class will
become familiar with the important and often critical environmental
sampling statistical concepts in order to develop defensible
sampling designs. |

9:30
am - 10:00 apm Module
3: Visual Sample Plan Demonstration
Presenter: Sebastian Tindall
The development of a sample plan involves evaluating trade-offs
between decision error, sampling costs, and remediation costs.
Visual Sample Plan software provides a quick and easy way
to visualize the impacts of various sample designs. |

4: The EPA 7-Step DQO Process (Steps 1 - 7)
Presenter: Sebastian Tindall
This module presents the EPA 7-Step DQO Process in an abridged
version of the "Day 1" course, removing much of
the detail due to time constraints, and presenting an overview.
Each step is discussed in terms of the information that is
needed to begin the step, the actions that need to be performed,
and the information that is needed to conclude a given step
and begin the next step. |

am - 11:50 am Module
5:The ERC DQO Web Page and DQO Workbook
Presenter: Sebastian Tindall
This module takes the class on a tour of the ERC DQO Web
Page, displaying and demonstrating the many DQO materials
and tools developed to support the DQO Process, including
the DQO Electronic Template (DQO Workbook). |
11:50
am - 12:00 pm Module
6: Closing Remarks
Presenter: Sebastian Tindall
Key points to remember are summarized in this module.
They all highlight how the DQO process helps you make order
out of the chaos of regulations, standards, and requirements
that surround collecting and analyzing environmental data.
