What hazardous materials are found in F019 wastewater sludge from motor vehicle manufacturers?
A. A review of the Material Safety Data Sheets (MSDS) for the chemicals used in, and prior to, the conversion coating process indicates that a wide range of elements can be expected to be present in the wastewaters and sludges resulting from wastewater treatment. For example, some of the specific chemical constituents found in motor vehicle manufacturers’ F019 sludge, include nickel, fluoride, zinc, barium, copper, chromium, tin, formaldehyde, lead, mercury, and xylenes. Top of Page Q. How did EPA determine that this change is fully protective of human health and the environment? A. EPA assessed the possible risks that could arise from the disposal of the waste in landfill scenarios. We used several models to evaluate risks arising from the potential releases of a broad range of constituents from the waste into the environment. Of particular concern was the potential for the waste to enter groundwater, which could result in the exposure of nearby groundwater users. After evaluating ris
