I'm just thinking about a process whereby a veteran comes in and makes a claim for exposure, and there is a list of all the sites where he's been. The computer can then crunch the numbers and get some sort of relationship between them.
Is the onus on the former service member to come forward and say, “I heard there were some contaminated substances at sites X, Y and Z,” or is there a list of soldiers and members who worked at one of these sites, and we reach out to them?
