Has to be the same neighborhood, near the Richmond Chevron refinery. I think the ponds I saw were operated by tiny firms, not Chevron. Guys who had a single truck to go get used oil. And who possibly misrepresented what they sold. Shoestring operations, before there were environmental laws.That sounds bad. Like really bad.
... wikipedia says about the Castro Cove area ...
Does that sound like it might be the mudflats that you saw?
That's news! Moving worldwide administration to Texas? Ok, whatever.Chevron has put its world headquarters campus on the market with lots of staff moving to Texas I hear.
There's an abandoned rail yard and roundhouse site in Roseburg. They used to treat railroad ties by dumping a tanker load of creosote into a hole in the ground and soaking ties in it. The black goo is still seeping out of a vertical ditch cut on the west side, and the ditch runs right into the river. The remnant of boiler repair from the age of steam is a layer of asbestos insulation, lead, and other random materials. Nobody was concerned about cleaning up their mess in the olden days. We're still living with it.It's interesting to see photos of those salt flats in the South (SF) Bay, in aerial photos.
Your comment brought to mind something I hadn't thought about in 70 years: When US40 (Now I-80) ran near sea level in the Richmond/Pinole/Hercules part of the East Bay by the big refineries, you could see ponds in the mud flats by the shore where used motor oil was 'reclaimed' by letting the contaminants settle out. I recall asking my father if this was ecologically rational (using whatever words were common then). He said don't worry, they know what they're doing.
I hate to think what's in the residual mud there now.
100% all natural ...Yep… the logic I read somewhere it’s from the earth and we return it to earth…
This the roundhouse foundation in Roseburg?There's an abandoned rail yard and roundhouse site in Roseburg.

We just know better now. I grew up playing with mercury and following the DDT Fogger Truck down the alley.
Yep… I’m worried myself on the DDT truck as we though it was great pacing with our bikes…
That's the site. The ditch is on the left side of the property along the street. The old creosote soak pit is part of the rough ground on the lower left.
Yep, that is what the planes were spraying!Malathion is my guess?
What?There was a recent article from the Netherlands was about a grocery store that stopped selling a certain brand of bottled water. The bottled water was processed from sea water made drinkable by reverse osmosis powered by solar panels. Activist(s) were complaining that the water was made from sea water, people were drinking bottled water in the first place, and there was a problem with recycling the bottles. The article was vague on why the grocery store stopped selling the water.
Later,
