The Michigan Department of Environment Great Lakes & Energy (EGLE) define Biosolids as "nutrient-rich organic materials, which remain following the treatment of domestic sewage at a wastewater treatment plant (WWTP). ... Biosolids are typically beneficially used on agriculture land, although under certain conditions biosolids can be used on forest lands, reclamation sites and public use sites."

Decades of studies have demonstrated that biosolids can be safely used on food crops. The National Academy of Sciences has reviewed current practices, public health concerns and regulator standards, and has concluded that "the use of these materials in the production of crops for human consumption when practiced in accordance with existing federal guidelines and regulations, presents negligible risk to the consumer, to crop production and to the environment." In addition, an epidemiological study of the health of farm families using biosolids showed that the use of biosolids was safe.

We work with EGLE on all monitoring and reporting of our product. Below you will find the frequency.

The plant consists of two geographically separate treatment facilities, the East Boulevard Wastewater Treatment Plant and the Auburn Wastewater Treatment Plant. The East Boulevard Plant has a present average daily flow of 5 million gallons per day and the Auburn Plant has a present average daily flow of 14 million gallons per day. The two plants are interconnected, operated, and regulated like a single combined wastewater treatment plant.
