The coffee-brown waters make the San Jacinto River appear unappealing from the Interstate 10 bridge. And it's worse than it looks. Below the rusty barges, sooty tugboats and floating trash is a poisonous bisque of long-lived chemicals that poses a health risk to people who regularly eat fish from these waters.
