A truck that spilled treated human waste fertilizer Monday in New Bern had some of our viewers voicing concerns about product safety.
We did some research about the material called biosolids. It can be used in soil to grow several crops- including those we eat. The process is heavily regulated by the EPA and takes place at waste treatment facilities. Greenville Utilites showed us the dewatering process at its plant Wednesday which creates biosolids. Officials with the Pitt County Cooperative Extension say the EPA requires monitoring of several factors.
"They've also regulated what can be exactly in the sludge as far as mineral content, pathogen load, and other potential pollutants that can be in the crops," said Andy Burlingham with the Cooperative Extension.
The use of biosolids also helps keep more waste out of landfills.
