Charlottesville, VA – With the price of oil rising, and the price of petroleum-based fertilizer going up, more farmers are considering sludge from sewage treatment plants.
They can get it free, but the state isn't 100% sure about the safety of so-called biosolids, and the Department of Environmental Quality is working on new guidelines for how and where they're used.
In the meantime, some farm neighbors are uneasy.
