The production of treated municipal sludge requiring disposal or recycling has increased substantially in the last 10 years as a result of more stringent waste-water treatment requirements. In 1974, for example, there were 3.2 million dry tons of sludge requiring disposal. By 1982 that number had more than doubled to 6.5 million dry tons/year. Land application of municipal sludge is widely practiced in the United States as a method of handling these increasing tonnages. For wastewater treatment plants with less than 10 mgd capacity, 39 percent of the sludge produced is managed by land application. Currently, for all size treatment plants, about 25 percent of the nation's sludge is land applied. The experience with land application has shown it to be a safe and effective sludge management practice. In particular, research and studies of the practice over the past 10 years have produced new knowledge which allows the benefits of land application to be realized with minimal adverse impact. 11 references.
