Residuals

Residuals may not be the prettiest material. But to crops hungry for nutrients, they can be a beautiful sight. Residuals are the organic, nutrient-rich solid, semi-solid, or liquid residues removed from wastewater during the treatment process. They can be incinerated or sent to a landfill. However, if they are of sufficient quality, they may be applied to farmland as a fertilizer. Such residuals are often called biosolids.

Since its creation in 1993, NEIWPCC's Residuals Workgroup has been working to enhance interstate communication on issues associated with residuals from wastewater treatment, on-site sewage disposal, and drinking water treatment. The workgroup meets 3-4 times a year, and is comprised of NEIWPCC and EPA staff along with the residuals coordinators of our member states' environmental agencies. Through the workgroup, NEIWPCC works to promote compatibility among state and federal sludge and septage management programs. We provide a forum for interstate discussion as well as technical assistance and coordination.
