Water Survey
The OPAL water survey launched in May 2010 and is coordinated by University College London (UCL). The survey asks people to go pond-dipping and identify the invertebrates living in their local pond or lake. Using this information they can then find out how polluted the water is, as some creatures are more tolerant of pollution than others. Results are collected online and will help scientists learn more about lakes and ponds across England.

Famous quotes containing the words water and/or survey:
“We’ve only just begun to learn about the water and its secrets, just as we’ve only touched on outer space. We don’t entirely rule out the possibility that there might be some form of life on another planet. Then why not some entirely different form of life in a world we already know is inhabited by millions of living creatures?”
—Harry Essex (b. 1910)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
