“Over 20 million acres of US cropland may be contaminated with PFAS from biosolid fertilizers.”

At Farmonaut, we’re deeply concerned about the growing PFAS crisis in US agriculture and its potential impact on water safety. As pioneers in satellite-based farm management solutions, we believe it’s crucial to shed light on this pressing issue that affects farmers, consumers, and the environment alike. In this comprehensive investigation, we’ll explore how biosolid fertilizers containing PFAS (per- and polyfluoroalkyl substances) are posing significant threats to our agricultural lands and water supplies.

Understanding the PFAS Crisis in Agriculture

PFAS contamination in agriculture has emerged as a critical environmental and health concern in recent years. These “forever chemicals” are persistent synthetic compounds that don’t break down easily in the environment, leading to long-term contamination of soil and water resources. The use of biosolids as fertilizers has inadvertently introduced these harmful substances into our food production systems, creating a complex web of challenges for farmers, regulators, and consumers.

The Rise of Biosolids in US Farming

Biosolids, derived from treated wastewater residuals, have been marketed as a safer and more sustainable alternative to traditional fertilizers. Rich in nutrients, these products have gained popularity among farmers seeking to enrich their soil and boost crop yields. Currently, nine US states are authorized to produce and utilize biosolids in agriculture and mining operations:

Arizona
Idaho
Michigan
Ohio
Oklahoma
South Dakota
Texas
Utah
Wisconsin

However, the widespread use of biosolids has led to unintended consequences, particularly concerning PFAS contamination.

The Hidden Dangers of PFAS in Biosolids

PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are a group of man-made chemicals known for their water and oil-resistant properties. These “forever chemicals” have been used in various industries for decades, from non-stick cookware to firefighting foam. Unfortunately, their persistence in the environment has led to widespread contamination, including in wastewater treatment plants where biosolids are produced.

When biosolids containing PFAS are applied to agricultural land, these chemicals can:

Leach into groundwater and contaminate drinking water supplies
Accumulate in soil, affecting crop growth and yield
Be taken up by plants and enter the food chain
Bioaccumulate in livestock, potentially affecting animal health and food safety

State Responses to the PFAS Crisis

As awareness of the PFAS crisis grows, several states have taken decisive action to protect their agricultural lands and water resources. Maine and Connecticut have led the charge by implementing bans on the use of biosolids in agriculture.

“Maine and Connecticut have banned biosolids in agriculture, potentially affecting thousands of farms.”

Maine’s Pioneering Legislation

In 2022, Maine became the first state to legislate a ban on the use of wastewater and compost biosolids due to alarming levels of PFAS contamination. This decision came after investigations revealed elevated PFAS levels in the state’s drinking water, soil, and agricultural produce. The ban aims to prevent further contamination and protect public health.

Connecticut Follows Suit

Following Maine’s lead, Connecticut enacted a similar ban on biosolid products in 2023. The state’s action reflects growing concerns over PFAS contamination of water sources and the potential long-term impacts on human health and the environment.
