Last month, the Environmental Protection Agency revealed that Volkswagen had installed a secret software cheat in nearly 500,000 of their diesel engine vehicles.
Today the Environmental Protection Agency (EPA) announced additional vehicle emissions testing in response to Volkswagen cheating at the tests since 2008, though many questions remain about which cars, and how many, will ultimately be subjected to them.
In the 1970s, several studies turned up pharmaceuticals in treated U.S. sewage water, and drugs have been a known unknown in water supplies ever since. Recently, researchers at the Environmental Protection Agency tested 50 U.S. wastewater-treatment plants serving more than 46 million people for 58 common drugs. They found many of the meds, but thankfully at concentrations so low it would take years to drink a full dose. -Jessie Geoffray
