Bee Killing Pesticides Contaminate Drinking Water
Neonicotinoids, pesticides linked to bee die-offs around the world, are another water contaminant Americans have to contend with. Water testing by the U.S. Geological Survey (USGS) in 2015 showed neonicotinoids are present in more than half of all streams tested.
Similar findings were recently made in Switzerland by the Swiss Federal Institute of Aquatic Science and Technology.7 There, watercourses were found to be contaminated with 128 different agricultural chemicals: 61 herbicides, 45 fungicides and 22 insecticides.
All streams and brooks tested failed to meet Swiss water quality standards. Thresholds for acute toxicity to aquatic life were also exceeded.
Now, a team of investigators at the USGS and the University of Iowa report8 finding three different neonicotinoids — clothianidin, imidacloprid and thiamethoxam — in all samples of treated drinking water.9,10 Water treatment facilities simply are not equipped to filter out most pesticides.
The water samples were collected from taps in Iowa City and on the University's campus. Measured in parts per trillion, neonicotinoids were found at concentrations ranging from 0.24 to 57.3 nanograms per liter.
While the concentrations were quite low, there's really no telling what the health effects might be, especially when you consider all the other chemical contaminants found in most tap water. Research has shown that even non-toxic ingredients can have toxic effects when combined.
By acting on various pathways, organ systems, cells and tissues, the cumulative effects of non-carcinogenic chemicals can act in concert to synergistically produce carcinogenic activity. As noted by lead author Dr. William Goodson:11
"[W]hat we're realizing ... [is] that there's reason to think that it doesn't take one chemical to take it all the way from normal to cancer. One chemical can take it part way, another chemical will take it another portion of the way, and maybe a second, third or fourth chemical will take it all the way."
