It all started with the smell. About five years
ago, just after Elvis Licul and his wife moved into
their farmhouse northwest of Longmont, they detected the odor. It was coming from a field
across the road to the west, where a farmer was using biosolids, or treated human sewage, to fertilize
his land for growing hay.Turns out, the stuff is free, provided to farmers by municipal wastewater facilities that are happy to 'recycle' the highly diluted liquid (no more than 5 percent is sewer solids).
