sewer sludge .. good?
We just bought a load of the city sewer sludge that has been sterilized to use on the lawns. The City recycles this sterilized material for use on City parks, golf courses,etc & now bags & sells it to local stores I understand. Any ideas as to safety, beneficial uses in this? I understand the bacteria, viruses may be treated & material safe in that respect but what about other products in a city sewage sludge: drugs, chemicals, etc.... anything flushed down the sewers would wind up in the sludge & not removed??
