We're looking more into reports of radiation in local drinking water.
Because of the nuclear trouble in Japan, water treatment facilities throughout the country were tested for a second time in a month, and Philadelphia got some bad news.
All three of our local facilities show radiation levels higher than average.
In fact, the levels of iodine 131 were high enough that the plants ranked in the top five out of 69 tested nationally.
The picocurie levels for the water at the plants ranged from 0.46 to 2.2. The EPA says you don't have to worry until you hit 4.0.
The agency says that, in a typical day, Americans receive doses of radiation from natural sources that are about 100 times higher than what's been detected here.
An expert Fox 29 News spoke with says if any level of radiation is detected, we should be taking steps to decontaminate the water.
The Philadelphia Water Department says it's working with the EPA and state to track down the exact sources of the iodine 131.
How much do we need to be concerned about this fallout from Japan's Fukushima plant, and is Philly's tap water safe to drink? Dr. Mike Cirigliano joined "Good Day" on Tuesday morning to give his take.
