[QUOTE="rdbigfarmboy, post: 506848, member: 6318"] Sludge is devided into classes. The cleaner sludge is not restricted as to where you can put it. The sludge with heavy metals in very tiny amounts like 2 parts per million for some constituents has to go to landfills or be further processed. Its important to understand someone has already made the decision as to how clean of toxics the sludge must be. The regs dont require testing for everything. Most of the stuff mentioned in previous post is organic and has a very short half life. Stuff like silvex (245T) or pcbs or many other pesticides has a very long life in the tissue or the soil. Most drugs, pills, sharps, and diseases are simply destroyed by the chemicals and physical processing. Sunlight time and heat also break down organics. The process depends on the honesty of generator of the sludge, the treatment plant personnel obeying the regulations, the analytical laboratory being honest, and correct proper ethical decisions being made. Tons of regulations can be circumvented by a bad player wanting to save a buck. Personally I would use class A clean sludge if it were available. [/QUOTE]
