[QUOTE="mtnhunter, post: 1739245, member: 20494"] So I have been reading these threads and see valid points on both sides. I have worked at the County wastewater plant for the last 35 years. I am the responsible official in charge of the Land Application of residuals ( Spreading human waste on fields). The treatment process we use meets all EPA requirements for beneficial reuse of organics. I guess the question here is do the EPA regulations go far enough to protect public health. None of the analysis we are required to do addresses prescription drug residues. Using sludge as a soil amendment has helped me and other farmers that use it increase hay and pasture yields substantially. Our county does not have any industries such as nickel plating operations or other heavy metals so the analysis of our sludge shows very low levels of heavy metals such as cadmium. We heat the sludge at 450 degrees and dry it to > 90% solids. The worst part of using it is the dust created because it is so dry. I think it is a more natural product than chemical fertilizers but there is insufficient data to tell us if this is a problem or just part of a long list of things that is going to kill us all at some point [/QUOTE]
