(VinePair) - Promise, this isn’t a fear-mongering post. But you could be drinking unsafe amounts of arsenic RIGHT NOW. Just kidding. Sort of.

Not too long ago, the University of Washington conducted a study of 65 wines from four of the major wine-producing states in the Union—New York, California, Washington, and Oregon. Turns out that all but one—wine, not state—contained levels of arsenic that actually exceed the amount of arsenic considered safe in drinking water.

That safe level, for those of us who aren’t up on our arsenic facts, is 10 parts per billion—a miniscule amount, so don’t freak out if you’re drinking a delicious glass of tap water. But the wines tested went almost 150% over the limit, with an average of 24 parts per billion. (The highest wine tested had a whopping 76 parts per billion of arsenic.) Washington State was apparently the worst offender in the study, producing wines with the highest levels of arsenic (possibly due to pesticide residue). Oregon, on the other hand, had the lowest levels of arsenic on average.

The study wasn’t the only evidence of arsenic in wine. BeverageGrades is a wine-analysis library run by Kevin Hicks, and their study of 1,300 bottles of California wine found arsenic levels that were also three, four, and five times as high as the EPA-designated arsenic limit for water. Unfortunately for those of us on a budget, Hicks also noticed a pattern in his study: “the lower the price of wine in a per-liter basis, the higher the amount of arsenic.” Meaning the savings on that Two Buck Chuck might not be worth it (well, at least their White Zinfandel).
