Right now! You should file a claim for benefits if you haven’t already. You can’t lock in a potential effective date until you file a claim, so it’s better to do that now, even if you don’t have all the evidence you need to prove service connection. Even if you can’t prove a connection to service now, there is a good possibility in the future that the VA will include additional military bases on the list of presumptive exposures to contaminated water just as they have for Camp Lejeune. When that happens and that information is released, we will certainly provide the information as well as provide assistance for our clients in filing a Supplemental Claim or an appeal as appropriate.
