Q. When are you going to update the software?
A. For any major revision, we must get funded to do so. EPA has funded Purdue University
to create these programs under cooperative agreements. If a program
needs to be updated, we must find funding from the appropriate program
office in EPA.
Updates to factual information -to correct errors, or to reflect scientific
findings or changes in policy- are generally being done on an ongoing basis.
Q. Can you link to my Web site? We produce environmental software too.
A. We may not link to commercial Web sites for the purpose of promoting their products. We do sometimes link to sites of other government agencies or nonprofit organizations.
