This is essentially right. I'll add the caveat that the Navy's water system apparently reaches many houses and businesses that you wouldn't call "on the navy base." Watching that unfold was painful, like when a network goes down and the operators clearly don't know their own network. This includes housing neighborhoods for other military service members (i.e. Army, Coast Guard) who work elsewhere, run by a different property manager, and neighborhoods that were transferred back to the civilian community 10-20 years ago. As mentioned in my other comment, what's most scary is that there's still no solid theory of what happened and when. We aren't sure of the chemicals, the amounts, the timeline, or the mechanism by which the chemicals got into the water. The story keeps changing, and never really adds up. So it does seem quite possible that the whole aquifer is at risk. The city plans to avoid drawing from this portion of the aquifer for several years now.
