Field Green® Biosolids

A product of WLSSD’s wastewater treatment process, Field Green® biosolids are delivered and spread on farm fields and taconite tailings basins in the Northland. WLSSD staff oversee and handle Field Green® from production through spreading. Each field is carefully inspected to ensure it’s suitable for the program, and buffer zones are established to protect waterways and wetlands. For more information, see our Field Green® page.
