The presence of blood worms in the city of Colcord, Okla.'s water supply has residents very worried. The outbreak has shut down schools, prevented convenience stores from selling sodas and residents have been advised to stop using tap water.
Blood worms are common in the southeastern part of the U.S., typically living in polluted or low-oxygen bodies of water. They're the midge fly larvae, and, much to the chagrin of Colcord, are able to survive bleach and chlorine. Though they don't present any health risks, it's pretty clear why worms in your water are cause for concern.
Officials in Colcord are attempting to rectify the situation by providing residents with bottled water while they investigate the origin of the worms.
