Congress is set to update a 40-year-old law regulating toxic chemicals in everyday products. But a watchdog group says the new regs were basically written by and for industry.
The bad news: Authorities estimate there are tens of thousands of lead water pipes in Philadelphia and Pittsburgh. Even worse, no one knows exactly where they are.
While others settled fracking lawsuits, two Pennsylvania families remain resolute in pursuing their case against one of the biggest drillers in the region.
Scientists have known for a long time that even low levels of lead can cause neurological problems in children. But a new study shows those impacts may be felt for generations.
Back in the early 20th century, lead was considered the "Cadillac" of materials when it came to water pipes. And many cities are still dealing with the harmful impacts of lead's legacy.
