EPA moves to make polluters foot the bill for PFAS cleanup
By Shannon Kelleher
US regulators on Friday finalized a rule designating two widespread PFAS chemicals as hazardous substances, a step they say will ensure polluters pay to clean up contamination and reduce Americans’ exposure to the toxic chemicals.
Under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or Superfund law, the rule will require leaks and spills of these per- and polyfluoroalkyl substances (PFAS) to be immediately reported and will enable investigation and cleanup of the chemicals.
The finalized rule “enables the agency to use one of its strongest enforcement tools to compel polluters to pay for or conduct investigations and cleanup, rather than taxpayers,” said the US Environmental Protection Agency (EPA) in a press release. “Designation is especially important as delay in addressing contamination allows PFOA and PFOS more time to migrate in water and soil, worsening existing contamination.”
“This is great news for the many communities grappling with PFAS contamination – many of which are also low income and communities of color,” said Tracey Woodruff, an environmental health researcher at the University of California, San Francisco and a former EPA senior scientist.
The move comes days after the EPA announced the nation’s first legally enforceable drinking water limits for the same chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), along with four other PFAS.
So-called “forever chemicals,” which do not break down naturally, have been used for decades in consumer products ranging from nonstick pans to waterproof clothes and stain resistant carpet. Exposure to PFAS has been linked to cancers, liver and heart problems, and immune and developmental damage in children, according to the EPA. The chemicals are found in the blood of almost all Americans.
“Sustainable” company behind POM juice among California’s top paraquat sprayers
By Shannon Kelleher
The Wonderful Company, which has been recognized for its sustainability initiatives and owns POM pomegranate juice, Fiji Water, and other popular brands, was among California’s top sprayers of the toxic weedkiller paraquat in 2021, according to a new analysis.
The major agricultural company, which grows pistachios, almonds, and pomegranates, was California’s second largest sprayer of paraquat, which has been linked to Parkinson’s disease. Wonderful accounted for over 13% of the state’s paraquat use, applying almost 57,000 lbs to its fields, according to the analysis published Thursday by the Environmental Working Group (EWG), which drew from data obtained from the California Department of Pesticide Regulation and county agriculture commissioners.
The company’s website states that “environmental sustainability is at the center of our work” and that the company, “in all its operations, must be a deeply responsible steward of the environment, and lead by example to create a sustainable future.” Wonderful has invested $400 million in sustainable agriculture, according to its website.
The Wonderful Company did not immediately respond to request for comment.
Just ten farms and companies in the top agricultural state sprayed 40% of all paraquat used in California in 2021, the analysis found. The biggest paraquat user in the state was the J.G. Boswell Company, a major producer of cotton, tomatoes for paste, and seed crops, which also accounted for over 13% of California’s paraquat use that year.
“Folks have known about paraquat for a while…but I think it’s clear the public doesn’t fully appreciate where these pesticides are being applied and how close it is to their communities,” said Geoff Horsfield, a policy director at the Environmental Working Group who works on pesticides and other agricultural issues.
Healthy or high risk? New analysis warns of pesticide residues on some fruits and veggies
By Carey Gillam
Several types of fruits and vegetables generally considered to be healthy can contain levels of pesticide residues potentially unsafe for consumption, according to an analysis conducted by Consumer Reports (CR) released on Thursday.
The report, which is based on seven years of data gathered by the US Department of Agriculture (USDA) as part of its annual pesticide residue reporting program, concluded that 20% of 59 different fruit and vegetable categories included in the analysis carried residue levels that posed “significant risks” to consumers of those foods.
Those high-risk foods included bell peppers, blueberries, green beans, potatoes and strawberries, according to CR. The group found that some green beans even had residues of an insecticide called acephate, which has been banned for use on green beans by US regulators since 2011. In one sample from 2022, levels of methamidophos (a breakdown product of acephate), were more
than 100 times the level CR scientists consider safe. In another sample, acephate levels were 7 times higher than CR considers safe.
Overall, out of the nearly 30,000 total fruit and vegetable samples for which CR examined data, about 8% percent were deemed to have residues at “high risk or very high risk”. Imported produce was more likely to carry high levels of pesticide residues than domestically supplied foods, the report said, noting that residue levels can vary widely from sample to sample.
The results “raise red flags,” according to CR. The report advises that children and pregnant women should consume less than a serving a day of high-risk fruits and vegetables, and less than half a serving per day of “very high-risk ones.”
“People need to be concerned because we see that the more data we gather on pesticides, the more we realize the levels that we previously thought to be safe turn out not to be,” said Michael Hansen, a senior scientist at CR who was recently appointed to a USDA food safety advisory committee.
The organization said the “good news” is that the data showed residues in most of the foods sampled, including 16 of 25 fruit categories and 21 of 34 vegetable types, presented “little to worry about.” Nearly all organic samples showed no concerning levels of pesticide residues.
The report suggests consumers “try snap peas instead of green beans, cantaloupe in place of watermelon, cabbage or dark green lettuces for kale, and the occasional sweet potato instead of a white one.”
EPA called to address “long-ignored health crisis” in Iowa drinking water
By Carey Gillam
US regulators must take immediate action to address a “long-ignored health crisis” stemming from dangerously contaminated drinking water in Iowa, according to a legal petition filed by environmental and health advocacy groups this week.
The Iowa Environmental Council (IEC) and 12 other organizations are calling for the Environmental Protection Agency (EPA) to take a series of steps to reduce harmful nitrate pollution found in water supplies in Northeast Iowa.
The petition highlights the fact that for many years, nitrate concentrations found in thousands of private wells and some public water sources have exceeded the federal limit of 10 milligrams per liter for drinking water.
State agencies have documented the contamination, but have “failed to do what is needed to correct the pervasive threat to human health,” the petition states.
“For decades, Northeast Iowa residents have been exposed to dangerous levels of nitrate contaminated water,” Food & Water Watch attorney Dani Replogle said in a press release. “As the state reckons with high cancer levels and ongoing pollution regulation rollbacks, federal action is needed to safeguard the right to clean water. EPA must exercise emergency authority to hold polluters accountable and deliver safe drinking water in Iowa.”
Food & Water Watch is among the groups joining IEC in its petition. Others include the Environmental Working Group, the Center for Food Safety, the Environmental Law & Policy Center, and several state organizations.
All signs indicate that “dangerous contamination levels will continue or worsen, absent EPA action,” the petition states.
Farm operations are largely to blame for the contamination, both from the runoff of fertilizer applied to fields of corn and other crops, and the runoff of liquified manure generated by large livestock operations that is also often spread on farm fields. The runoff carries nitrates and phosphorus into surface and groundwaters, and ultimately drinking water.
Iowa is one of the nation’s largest farm states for crops and livestock, and Northeast Iowa is particularly vulnerable to farm pollutants because of its “karst” terrain, which features porous limestone that allows surface pollutants to more quickly move into groundwater. All of the drinking water in the karst region of northeast Iowa depends on groundwater aquifers.
Despite these facts, only a small fraction of private wells are tested regularly for nitrates, which are known to cause health problems at high levels, especially for infants. Cancer is a specific concern with nitrate exposure. Still, more than 1,200 wells in the 12-county karst region tested above the federal threshold for safety from 2016 to 2023, the petition states.
