Excerpt
Introduction: Municipal sewage sludge, the product of secondary and tertiary wastewater treatment. presents an increasingly burdensome disposal problem to sanitary districts of all sizes. Surface land disposal is an attractive alternative, but there are some potential hazards. Accumulation of toxic trace elements is the current primary concern and cadmium is the trace element receiving the most attention. Trace element composition of digested sewage sludges is highly dependent on the city of origin and on the metal processing activities within the recipient sanitary district (I). Heavy sewage sludge application to agricultural soils for several years results in significantly increased concentrations of nutrient elements, increased organic matter and moisture holding capacity, and does not adversely affect microbial action (2).
