Juana Valle never imagined she’d be scared to drink water from her tap or eat fresh eggs and walnuts when she bought her 5-acre farm in San Juan Bautista, California, three years ago. Escaping city life and growing her own food was a dream come true for the 52-year-old.
Then Valle began to suspect water from her well was making her sick.
“Even if everything is organic, it doesn’t matter, if the water underground is not clean,” Valle said.
This year, researchers found worrisome levels of chemicals called PFAS in her well water. Exposure to PFAS, a group of thousands of compounds, has been linked to health problems including cancer, decreased response to vaccines, and low birth weight, according to a federally funded report by the National Academies of Sciences, Engineering, and Medicine. Valle worries that eating food from her farm and drinking the water, found also to contain arsenic, are to blame for health issues she’s experienced recently.
The researchers suspect the toxic chemicals could have made their way into Valle’s water through nearby agricultural operations, which may have used PFAS-laced fertilizers made from dried sludge from wastewater treatment plants, or pesticides found to contain the compounds.
The chemicals have unexpectedly turned up in well water in rural farmland far from known contamination sites, like industrial areas, airports, and military bases. …
