Taking a Dive

The investigation into how zebra mussels (Dreissena polymorpha) were introduced to the Milbrook Quarry in Virginia continues. According to this article from Hampton Roads Daily Press, the fact that the quarry is frequently used for scuba training had led officials to point their fingers at divers, reasoning that the invasive species were introduced intentionally to clear up the water. The dive community is denying responsibility, and some are suggesting that the zebra mussels could have been introduced accidentally through contaminated diving equipment or by waterfowl, especially since juveniles are very tiny and difficult to detect. Sounds like it's time for Virginia to kick their public education campaign, which asks divers, boaters, etc. to clean their equipment prior to entering new body of water, into high gear.
