Small Group Exercise
Break into small groups and respond to the following
questions. If viewing live via the web, email responses to
[email protected].
1. How have you or your organization used the CEC
program’s guidance values, Information Sheets,
development documents, web pages, etc.?
2. How have these products had an impact? How can this
impact be increased?
3. In addition to public nominations what are other ways we
could identify contaminants for evaluation?
The Forum will re-commence at 2:45 pm following the break.
