Here's a nice web site.
Also some people are working on developing photocatalysts to do this. That may still be in the future though.

Boiling is not a reliable method. The link given by an earlier answerer is a good one. I have used the iodine method a fair bit and for camping it is pretty convenient. It doesn't seem to produce a bad taste the way I find bleach does. You can buy the bottles with iodide in most camping stores.

If it's blue/green algae, I believe that bales of straw thrown into the water can fix the problem. After the bales absorb the algae, they are then removed from the water source and disposed of somewhere. I'm not sure if the bales are of any use to anything after this process. I suppose it would make good compost.

Add sodium hypochlorite (bleach) to the water to produce a concentration of 2 - 5 ppm (parts per million)

I'd say boil it for about 20 - 30 minutes just to be safe
