Title says tap water... article says rain water.
The synopsis is also wrong. The synopsis says that "3 Liters of rainwater collected contained 134 Becquerels of Iodine for an average of 20.1 Becquerel per liter", but this isn't the case (and in any case the average given those numbers would be 44.67 (134 / 3 = 44.67)). That data shows that 20.1 Bq/L of Iodine 131 were found (in three liters, meaning a total of 60.3 becquerel) and the parenthetical number (134) is "the number of liters of water that one would need to consume to equal the radiation exposure of a single round trip flight from San Francisco to Washington D.C. (0.05 mSv)."
