In my full time job, I am a metals analyst for an environmental company in Bentonville. I've analyzed all the sewer sludge headed for land applications in my area and most of the surrounding areas, as well as the municipal compost for the city and none of it has shown to be high or even contain significant levels of any of the metals - trace or heavy. The reason I do not use it myself is because I am concerned with the things I am not checking for, like drug/pesticide residues and other compound chemical contamination. But at least about the metals, I would not be worried.
