Sewage Sludge

Why is Toxic Sewage Sludge Dumped on Farm and Gardens?

"The policy of disposing of sludge by spreading it on agricultural land - a policy given the benign term 'land application' - has its inception in the Ocean Dumping ban of 1987. Before 1992, when the law went into effect, the practice had been, after extracting the sludge from the wastewater, to load it on barges and dump it 12, and later 106 miles off shore into the ocean. But many people who cared about life in the ocean knew that, wherever it was dumped, the sludge was causing vast dead moon-scapes on the ocean floor. New EPA regulations for 'land application' were promulgated in 1993. With the aid of heating and pelletizing and some slippery name morphs along the way, EPA claimed sludge could be transmogrified into 'compost' ... . But the land “application” of sewage sludge ... will pollute the whole chain of life for which soil is the base." [1] In 2002, the National Research Council found that the "U.S. Environmental Protection Agency's standards that govern using treated sewage sludge on soil are based on outdated science."[2] This was again confirmed in 2011 when scientists found that noroviruses survive treatment that kills pathogens such as Salmonella.[3]

In March 2013, a study involving neighbors of land where sewage sludge had been dumped -- "living in rural and semi­rural areas within approximately one mile of sewage sludge land application sites in North Carolina, South Carolina and Virginia" -- found that "over half of respondents attributed physical symptoms to application events." More specifically, "Over half (18/34) of the interview respondents associated acute physical symptoms that lasted a short period of time with sludge application events near their home (Table 1). The most commonly reported symptoms were eye, nose, and throat irritations and gastrointestinal symptoms (nausea, vomiting, diarrhea). Other symptoms reported by more than one respondent include cough, difficulty breathing, sinus congestion or drainage, and skin infections or sores."[4]
