I asked a question before , what will happen to fresh (pure) water below freezing point ?

umm.. remains frozen? did you assume that ALL snow/ice is an EXACT 0 degrees C in temperature? any water below 0 C is frozen water

There is a point where water can be below the freezing point in the atmosphere in meteorology and aerospace where it is called "supercooled", where certain circumstances are involved. Hope this helps a little. http://en.wikipedia.org/wiki/Supercooling Water has a freezing point of 273.15 K (0 °C or 32 °F) but can be supercooled at standard pressure down to its crystal homogeneous nucleation at almost 231 K (−42 °C).[1] If cooled at a rate on the order of 106 K/s, the crystal nucleation can be avoided and water becomes a glass. Its glass transition temperature is much colder and harder to determine, but studies estimate it at about 165 K (−108 °C).[2] Glassy water can be heated up to approximately 150 K (−123 °C).[1] In the range of temperatures between 231 K (−42 °C) and 150 K (−123 °C) experiments find only crystal ice. Droplets of supercooled water often exist in stratiform and cumulus clouds. They form into ice when they are struck by the wings of passing airplanes and abruptly crystallize. (This causes problems with lift, so aircraft that are expected to fly in such conditions are equipped with a deicing system.) Freezing rain is also caused by supercooled droplets. An equivalent to supercooling for the process of melting solids is much more difficult, and a solid will almost always melt at the same temperature for a given pressure. It is, however, possible to superheat a liquid above its boiling point without it becoming gaseous.

It will keep on freezing and become ice. Only way of preventing ice is to decrease the freezing point by adding an impurity (like salt). Pure (and still) water will become ice at zero Celsius, unless agitated which is a way to add heat to the water as you are moving the water molecules.

it turns to ice

Yes, water can remain as liquid below 0C if the pressure is greater than 1 atm. Sometimes if you freeze water too fast, water can remain as liquid even under 1 atm. This is called supercooling.

If you freeze it below zero (if quick enough I think.. not sure if speed is needed) then it will stay as a liquid. It only turns into ice and crystallizes when some heat is disbursed.

are you referring to "distilled water"?? it actually freezes faster than regular tap water, which has all the contaminents. Took some chemistry and physics classes. This is how i understand it. Water freezes at 0C or 32F. From there it is still frozen all the way to absolute zero -273.15C. So once it freezes it remains frozen to the lowest possible temperature. We have yet to achieve that -273.15C. There are other liquids which freeze under 0C for example Krypton. Or Helium is almost impossible to freeze. Just remember everything from chocolate, water, helium has a freezing and melting point. They change state from Solid to liquid to gas.

water will remain ice however low the temperature it may get however some types of water freeze at a much lower temperature down to -25C

http://serc.carleton.edu/images/research_education/equilibria/h2o_phase_diagram_-_color.v2.jpg check that site out. you can say that the freezing point depends on the pressure as well as temperature. according to that phase diagram, water will freeze even at 0 atm.
