PHILADELPHIA (AP) _ A total of 56 pharmaceuticals or byproducts have been detected in this city's drinking water, largely in tests conducted last year, according to the Philadelphia Water Department.

The list of drugs is the longest among 62 major water providers surveyed by the Associated Press. However, this city's water officials say they probably found more drugs simply because they did more testing. They say their water is safe to drink.
