"In the summer of 1984, investigators peered into a cave dug beneath the Lincoln Heights neighborhood of Los Angeles and found dozens of rusted 55-gallon barrels filled with toxic chemicals.
Some of the barrels lay nearly empty after their contents had leaked through corroded metal and escaped into the soil.
“I saw the hole and I said, ‘I can’t believe it — who would do something like this?’,’' recalled Barry Groveman, the head of the now-defunct Los Angeles Hazardous Waste Task Force. At the time, he described the dump as “a violent crime against the community.”
Groveman and his investigators went on to uncover 252 barrels buried in similar caverns surrounding a manufacturing warehouse at 141 West Avenue 34, where the American Caster Corp. operated. Some of the chemicals were also dumped into sewer lines. Before the discovery, the dumping practice had carried on for four years."
