The sludge comes from wastewater facilities after it has been treated to reduce pollutants and pathogens. Biosolids can be disposed of through incineration or buried in a landfill, but they can also be used as fertilizer on farms.
Since 2007, the Virginia Department of Environmental Quality has been in charge of issuing companies permits, and ensures that the companies applying the biosolids follow strict regulations, such as not allowing livestock to graze on biosolid-affected land for 30 days.
