Regulation on procedure and manner for use of sludge from the treatment of waste waters through their application in agriculture.

This Regulation determines the rules for the correct, controlled and safe use of sludge for agriculture purposes and/or related agricultural land activities and the requirements that sludge must meet in order to ensure a safe and non-harmful impact on human health, soil and environment (including the rules for frequency of sludge testing).
Sludge, object of this text, is a semi-solid slurry and can be produced as sewage sludge from wastewater treatment processes or as a settled suspension obtained from conventional drinking water treatment and numerous other industrial processes.
The Annex is part of this text (it also provides the list of official values for quantities of heavy metals that can be added annually in agricultural land, here based on ten years average).
