  • Scientists are using bacteria to remove harmful contaminants from our water. Here's how.

    It turns out that bacteria can do a lot more than contaminate water--some species break down toxic chemicals and remove heavy metals. Active sites already clean water in states like Kansas, Utah, Texas, and California; for example, one Californian groundwater treatment plant can clean 2,000 gallons of perchlorate-contaminated water per minute. Though some logistical and technical hurdles remain, these bacterial allies in the fight against water pollution are very promising.

  • Saving the Great Lakes, one laundry load at a time

    A pilot experiment in Canada shows that adding a filter on a washing machine can prevent microfibers from entering the wastewater system and ending up in marine ecosystems. After installing these filters on machines in a community, there was a 41 percent decrease of microfibers in the washing machine liquid waste. This will not keep all microfibers from ending up in the environment, but legislators are working on passing bills requiring manufacturers to get these filters installed on new machines.
