Most aircrew members / support personnel at Tahkli were exposed to herbicides if they performed duty near the perimeters i.e.,
a. Runway alert - normally done in marshalling areas at
runway ends.
b. Herbicide spraying was done on base perimeters.
Runway ends are on the base perimeters.
c. Result: Above personnel exposed to herbicide spraying or
residuals from prevailing winds.
Hopefully, this data should help with your VA Claims.
I was stationed at Tahkli as a B66C EWO - 2/67 - 9/67.
IMPORTANT: Link data updated in May 2012. Believe data was 1st published in 2011(?).
