“Nordell and Davis believe the contamination happened during the 1990s, long before they purchased the 20-acre farm in the heart of the central Maine farming community. Back then, both the Kennebec Sanitary Treatment District and the Portland Water District applied for and received licenses from the Maine Department of Environmental Protection to apply wastewater treatment plant sludge on the land. Treated sludge, also called biosolid compost, was widely used as a fertilizer.”

“We are farmers, not doctors or toxicologists, but it is our understanding that there is no immediate health risk from the vegetables and grain products you have already eaten. These PFAS chemicals represent a long term exposure concern rather than a single exposure risk. Knowing where they are present and reducing all of our exposure to them is what we are trying to do.”
Adam Nordell and Johanna Davis / PFAS Statement
“Are there PFAS in Milorganite? Yes, some PFAS were found in the popular fertilizer. PFOA and PFOS, two of the most well-researched forms of the chemicals, were both detected. PFOA was detected at 0.67 parts per billion, under 2.5 parts per billion limit for the chemical in Maine, which was used as the standard for the study because it has the strictest requirements for PFAS in biosolids. PFOS, however, was detected at 8.66 parts per billion in Milorganite, over the 5.2 parts per billion standard set by Maine. The study found that some precursors to PFAS were contained in the Milwaukee fertilizer as well, which degrade over time to form actual PFAS.”

“The PFAS issue in biosolids fertilizer is a relatively new issue, and there is no clear indication that Milorganite fertilizer has a PFAS build-up that need’s remediation. Experience has shown PFAS concentrations in biosolids vary significantly depending upon local conditions, such as the type of water supply, the presence of fire suppression training sites, and industries that manufacture or use PFAS. For Milorganite fertilizer, local conditions that contribute to the production of our product favor low concentrations. In fact, PFAS sampling for Maine, concentrations for two of the three analyzed compounds were below the level of detection and the third was slightly above the level of detection, confirming minimal PFAS risk.”
