A couple more little “fun” facts: Subic backed up against Olongapo City – 250,000 inhabitants and inadequate sewage treatment. Is it possible they have something to do with the water quality? How about all the Philipino shipyards that ring the bay? Mount Pinatubo dumping a foot of ash in the Bay had a lot more impact on the fisheries than the USN ever did. For most of its existence, Subic was pretty minor repair facility for the USN. It’s big build up happened during the Viet Nam days. As you guys obviously haven’t seen the base, here is a picture during its heyday in the late 70’s and a shot of it today.
Pearl’s problem is it was mostly a man-made harbor carved out of the mangrove delta of the Pearl River. The East Loch was dredged in part, to create a flushing action in order to maintain water quality and harbor depth. Alas, now that the Navy has reduced their footprint, they are allowing the Loch to silt back in and return to mangroves affecting water quality. I read somewhere that the biggest source of pollution at Pearl is the Arizona herself. But as a gravesite, there are no plans to disturb her by pumping her oil tanks.
