2. Microscopic Crustaceans Were Found in NYC Tap Water

In 2010, a Reddit user uploaded images of microscopic shrimp-like organisms found in a glass of tap water. What the user captured were copepods, very tiny crustaceans that are known to eat mosquito larvae and help keep water supplies clean. The presence of this organism, though invisible and harmless, posed a problem for Orthodox Jewish people who follow a Kosher diet in New York City. A NYC Department of Environmental Protection (DEP) spokesman told Wastewater Digest back in 2004 that the copepods can easily be filtered out with a commercial filter or the water could be run through a double cloth to remove the creatures.
