Sewage Sludge Problem in the world
The Clean Water Act and the Ocean Dumping Ban Act of 1988 eliminated all but land-based options for the “benefical use” or disposal sewage sludge. This fundamentally myopic approach to environmental protection teamed up with amendments to the Clean Water Act that pushed thousands of communities on to secondary treatment — a level of biological treatment that doubles the amount of sludge produced at wastewater treatment plants — to bring us the environmental and public health disaster we are now experiencing.
The treated effluent from wastewater treatment plants is now known to bring a vast array of wastewater contaminants, including personal care products and pharmaceuticals, into our nation’s water. Sewage sludge, the unavoidable byproduct of sewage treatment, is poisoning our food.
