If it is fairly low in toxins it should be put on the land. If its high in toxins they should not be released into the atmosphere. Regards, Steve

The sludge is good garden fertilizer, but I don't believe that food production should be based on sludge for long. We won't accept responsibility for the remote possibility of heavy metal build-up in the soil over time, and neither will our insurers or NJDEP. It's a shame, but the per-batch analyses, permit fees, and insurance costs price sludge as fertilizer -- small bootleg batches excepted -- out of the market.

Believe its not allowed to be used for food production. Its composted first.
