The article links to a USSOCOM-funded study. In your opinion, are they (as a whole) seriously concerned with mitigating this issue or is it just checking the box? The worry is this can be similar to the buried diesel tank issue contaminating water, which was known for decades but seemed to be ignored (possibly out of liability concerns).
I'm not sure how much of it you can minimize. You can only control what you can control...and war/combat is chaos. Honestly it seems most things in relation to this over the years has been on treatment, not so much prevention.
